Two-element ionic compounds and polyatomic ionic compounds are equally common. Polyatomic ions are ions comprised of more than one atom. A good example is the ammonium ion made up of one nitrogen atom and four hydrogen atoms. Ions that are negatively charged are called anions, pronounced “an-ions.”
When naming ionic compounds?
When naming ionic compounds, we follow the general rules: Identify and name the cation; this is a metal element or polyatomic cation. Identify and name the anion; this is a nonmetal element. Change the suffix to '-ide,' or use the polyatomic anion name.
What is an ion name in chemistry?
Naming Ions. The name of a monatomic cation is simply the name of the element followed by the word ion. Thus, Na+ is the sodium ion, Al3+ is the aluminum ion, Ca2+ is the calcium ion, and so forth. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3).

There are two types of ions: cations and anions. A cation has a net positive electrical charge, which means it has more protons than electrons. An anion has a net negative electrical charge, which means it has more electrons than protons.
Is h2o an ion?
H2O is not an ionic compound because the bond formed between hydrogen and oxygen is due to sharing of electrons. In ionic compounds, the bond is formed between two atoms by the exchange of electrons from one atom to another. There is no sharing of electrons involved in ionic compounds.

Body fluid contains electrolytes, chemicals which, when they dissolve in water, produce charged ions. These ions enable the flow of electrical signals through the body. Electrolytes play an important role in the body; they regulate the osmotic pressure in cells and help maintain the function of muscle and nerve cells.

Is Salt an ion?
In chemical terms, salts are ionic compounds. To most people, salt refers to table salt, which is sodium chloride. Sodium chloride forms from the ionic bonding of sodium ions and chloride ions. There is one sodium cation (Na+) for every chloride anion (Cl–), so the chemical formula is NaCl (Fig.
Which best describe an ion?
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
Who is Ion of Chios?

What is an ion?
An ion ( / ˈaɪɒn, - ən /) is a particle, atom or molecule with a net electrical charge .
Why are ions called ions?
So called because ions move toward the electrode of opposite charge. This term was introduced (after a suggestion by the English polymath William Whewell) by English physicist and chemist Michael Faraday in 1834 for the then-unknown species that goes from one electrode to the other through an aqueous medium. Faraday did not know the nature of these species, but he knew that since metals dissolved into and entered a solution at one electrode and new metal came forth from a solution at the other electrode; that some kind of substance has moved through the solution in a current. This conveys matter from one place to the other. In correspondence with Faraday, Whewell also coined the words anode and cathode, as well as anion and cation as ions that are attracted to the respective electrodes.
Why is the net charge of an ion non zero?
The net charge of an ion is non-zero due to its total number of electrons being unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons.
Why do electrons drift faster than positive ions?
Schematic of an ion chamber, showing drift of ions. Electrons drift faster than positive ions due to their much smaller mass.
What are ion sources?
Ions can be non-chemically prepared using various ion sources, usually involving high voltage or temperature. These are used in a multitude of devices such as mass spectrometers, optical emission spectrometers, particle accelerators, ion implanters, and ion engines .
Which type of ion has fewer electrons than protons?
A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds .
What is a zwitterion ion?
A zwitterion is a neutral molecule with positive and negative charges at different locations within that molecule.
What is the ionic compound?
Ionic compounds consist of cations (positive ions) and anions (negative ions). Ionic compound nomenclature or naming is based on the names of the component ions. In all cases, ionic compound naming gives the positively charged cation first, followed by the negatively charged anion. Here are the principal naming conventions for ionic compounds, ...
What is the name of the anions that contain oxygen?
Some polyatomic anions contain oxygen. These anions are called oxyanions. When an element forms two oxyanions , the one with less oxygen is given a name ending in -ite and the one with more oxygen are given a name that ends in -ate.
How are polyatomic anions named?
These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. It is still common to see and use the older naming convention in which the prefix bi- is used to indicate the addition of a single hydrogen ion.
What are the endings of ionic compounds?
Naming Ionic Compounds Using -ous and -ic. Although Roman numerals are used to denote the ionic charge of cations, it is still common to see and use the endings -ous or -ic. These endings are added to the Latin name of the element (e.g., stannous / stannic for tin) to represent the ions with lesser or greater charge, respectively.

Which molecules have single bonds?from en.wikipedia.org

What is the symbol of a diatomic molecule?from en.wikipedia.org
The molecular term symbol is a shorthand expression of the angular momenta that characterize the electronic quantum states of a diatomic molecule, which are also eigenstates of the electronic molecular Hamiltonian. It is also convenient, and common, to represent a diatomic molecule as two-point masses connected by a massless spring. The energies involved in the various motions of the molecule can then be broken down into three categories: the translational, rotational, and vibrational energies.
What is the lowest state of a diatomic molecule?from en.wikipedia.org
Diatomic molecules are normally in their lowest or ground state, which conventionally is also known as the#N#X {displaystyle X}#N#state. When a gas of diatomic molecules is bombarded by energetic electrons, some of the molecules may be excited to higher electronic states, as occurs, for example, in the natural aurora; high-altitude nuclear explosions; and rocket-borne electron gun experiments. Such excitation can also occur when the gas absorbs light or other electromagnetic radiation. The excited states are unstable and naturally relax back to the ground state. Over various short time scales after the excitation (typically a fraction of a second, or sometimes longer than a second if the excited state is metastable ), transitions occur from higher to lower electronic states and ultimately to the ground state, and in each transition results a photon is emitted. This emission is known as fluorescence. Successively higher electronic states are conventionally named#N#A {displaystyle A}#N#,#N#B {displaystyle B}#N#,#N#C {displaystyle C}#N#, etc. (but this convention is not always followed, and sometimes lower case letters and alphabetically out-of-sequence letters are used, as in the example given below). The excitation energy must be greater than or equal to the energy of the electronic state in order for the excitation to occur.

Another type of motion of a diatomic molecule is for each atom to oscillate—or vibrate —along the line connecting the two atoms. The vibrational energy is approximately that of a quantum harmonic oscillator :

Ions in their gas-like state are highly reactive and will rapidly interact with ions of opposite charge to give neutral molecules or ionic salts. Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce solvated ions, which are more stable, for reasons involving a combination of energy and entropy changes as the ions move away from each o…
