What's an ion in chemistry?
An ion is an atom or group of atoms in which the number of electron s is different from the number of proton s. If the number of electrons is less than the number of protons, the particle is a positive ion, also called a cation.
What is ion and anion?
Cations are positively-charged ions (atoms or groups of atoms that have more protons than electrons due to having lost one or more electrons). Anions are negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons).

How do ionizations occur?
Ionization happens by giving atoms high energy. This is done using electrical voltage or by high-energy ionizing radiation or high temperature. A simple ion is formed from a single atom. Polyatomic ions are formed from a number of atoms. Polyatomic ions usually consist of all non-metal atoms.
What are the two parts of an ionized atom?
An atom that is ionized makes two parts, one positive, and one negatively charged. For example, a neutral hydrogen atom has one proton and one electron. Ionizing the atom breaks it into two parts: (1) a positively charged hydrogen ion, H+ (2) a negatively charged electron. A liquid with ions is called an electrolyte.
Why is an ion charged?
It is " charged " so it will move near electricity. This is because atoms are made of three smaller parts: equal number of negatively-charged electrons.
What is the charge of an ion?
An ion has unequal numbers of protons and electrons. Making an ion from an atom or molecule is called ionization . The charge on a proton is chosen as +1 (positively charged). The charge on an electron is opposite to the charge on the proton. The charge on the electron is -1 (negatively charged).
What are transition metals attracted to?
They are attracted to anodes (positively charged electrodes). All simple non-metal ions (except H +, which is a proton) are anions. Transition metals can form more than one simple cation with different charges. Most ions have a charge of less than 4, but some can have higher charges.
What does an ion mean in Greek?
In Greek ion is like the word "go". "Anion" and "cation" mean "up-goer" and "down-goer". "Anode" and "cathode" are "way up" and "way down".
Do metal ions move?
For example, in a wire, the metal ions do not move, but the electrons move as electricity. A positive ion and a negative ion will move together. Two ions of the same charge will move apart. When ions move they also make magnetic fields . Many ions are colourless.
What is the driving force behind ionic bond formation?
It is important to make a note that the electrostatic forces of attraction which arise between the positively charged cations and negatively charged anions are described as the driving force behind the ionic bond formation. When the 2 oppositely charged ions produce an ionic bond with each other, the resulting compound type is commonly known as an ionic compound.
What is the name of an ion that holds a greater electron count than protons?
On the other side, ions that hold a greater electron count than protons are known to contain a net negative charge. Commonly, these ions are referred to as anions .
How do ions form?
The other important process via which ions can be formed is done by using chemical interactions. As an example, when an ionic compound like salt is dissolved in a suitable solvent (like water), the atoms that constitute that salt undergoes dissociation and produce free ions. However, when common salt, which is also called sodium chloride, is dissolved in water, it undergoes dissociation to generate chloride anions and sodium cations. It should also be noted that the symbol Cl denotes the chloride anions– and sodium cations are denoted using the symbol Na+.
What is the symbol for lithium cation?
Lithium Cation. The chemical symbol of the lithium atom is given as Li. Because the lithium cation carries a net charge of +1, the monoatomic ion is represented as Li⁺. Q2.
What does the symbol Cl mean in chemistry?
It should also be noted that the symbol Cl denotes the chloride anions– and sodium cations are denoted using the symbol Na+. Another important notable process via which ions can be formed is the passage of direct currents via some conducting solutions, which results in the production of ions in the solution.
What is an ion?
An ion can be described as a chemical species that hold either a positive or negative charge of some amount of magnitude. The word 'ion' can be used to refer to molecules or atoms that hold non-zero net charges associated with them. Thus, all the ions contain either a greater number of protons compared to electrons in their overall molecular ...
What are some examples of anions derived from organic compounds?

What is an ion in chemistry?
noun Physics, Chemistry. an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion ), which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion ), which is created by an electron gain and is attracted to the anode.
What is the valence of an ion?
The valence of an ion is equal to the number of electrons lost or gained and is indicated by a plus sign for cations and a minus sign for anions, thus: Na +, Cl−, Ca ++, S =. one of the electrically charged particles formed in a gas by electric discharge or the like.
What is the charge of salt?

What are positive and negative ions called?
Positive and negative ions have special names. Positive ions are called cations and negative ions are called anions . A way to remember which is which is to think of the prefix "anti", which generally has a negative connotation, just like an anion has a negative charge.
How many oxygen atoms are in carbonate?

How many atoms are in a monoatomic ion?
Monoatomic ions are made up of one atom with a charge ( {eq}H^+ , Cl^- {/eq}).
Why do nonmetals gain electrons?
Nonmetals most often gain electrons to stabilize, becoming anions. It would require less energy to gain electrons to be like the noble gas in their period as opposed to losing electrons to have an electron structure of the previous noble gas like the metals do. For example, fluorine is one electron away from having an electron structure like neon, but 7 away from being like the previous gas, helium.
Why is an ion positively charged?
An anion has more electrons and is negatively charged; a cation is positively charge because it has lost electrons.
What is a molecule?
Molecules are any two or more atoms that are bonded together. The atoms in a molecule can be the same, like in hydrogen gas (H 2 ), or different, like in water (H 2 O). Compounds must be made up of at least two different atoms that are bonded together. Both compounds and molecules can carry a positive or negative charge. When they do, they are also considered ions. The charge of an atom or molecule affects how it will behave in the presence of other particles and how it will bond.
What are the parts of an atom?
There are three parts to the atom. The nucleus of the atom has protons and neutrons, while the electron orbits a space around the nucleus. The positively charged particle as a proton. The negatively charged particle is an electron. The neutron is neutral, as its name suggests.
