Are protons and neutrons have the same number?
The number of protons in the nucleus of every atom of an element is always the same, but this is not the case with the number of neutrons.Atoms of the same element can have a different number of neutrons.Atoms want to have the same number of neutrons and protons but the number of neutrons can change.
What does the number of protons represent?
The number of protons in one atom of an element determines the atom's identity, and the number of electrons determines its electrical charge. The atomic number tells you the number of protons in one atom of an element. The atomic mass of an element is the total number of protons and neutrons in the nucleus of the atom.

How many electrons are in a neutral rhodium atom?
Therefore, the number of electrons in neutral atom of Rhodium is 45. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
What is the atomic mass of rhodium?
Atomic mass of Rhodium is 102.9055 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume ...
What is the electron affinity of an atom?
In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion. X + e– → X– + energy Affinity = – ∆H.
What is the electronegativity of rhodium?
Electronegativity of Rhodium is 2.28. Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used. The electronegativity of Rhodium is: χ = 2.28.
What is the total number of protons in the nucleus of an atom?
Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given ...
What is the first ionization energy of rhodium?
First Ionization Energy of Rhodium. First Ionization Energy of Rhodium is 7.4589 eV. Ionization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom.
What is the atomic number of an element?
Since the number of electrons and their arrangement are responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z.
What element has 2 protons?
The element of an atom with 2 protons is always helium. If you are given the atomic weight of an atom, you need to subtract the number of neutrons to get the number of protons. Sometimes you can tell the elemental identity of a sample if all you have is the atomic weight.
How many protons does a hydrogen atom have?
It's easy to get a hydrogen atom with one proton and one neutron (deuterium), yet you won't find a helium atom with an atomic weight of 2 because this would mean the helium atom had two protons and zero neutrons! If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons.
How to find the number of neutrons in an atom?
You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (the atomic number) from the mass number to find the remaining neutrons.
Why is the periodic table decimal?
Each atom has an integer number of neutrons, but the periodic table gives a decimal value because it is a weighted average of the number of neutrons in the isotopes of each element. So, what you need to do is round the atomic weight to the nearest whole number to get a mass number for your calculations.
What are the protons, neutrons, and electrons in an atom?
Key Takeaways: Number of Protons, Neutrons, and Electrons. Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out).
What does it mean when an ion has a 2+ charge?
If an ion has a 2+ charge, like Zn 2+, this means there are two more protons than electrons. If the ion has a 1- charge (simply written with a minus superscript), then there are more electrons than the number of protons. For F -, the number of protons (from the periodic table) is 9 and the number of electrons is:
How does the periodic table organize elements?
The periodic table organizes elements by the number of protons in their atoms. Andrew Brookes/Corbis/Getty Images
What is the periodic table?
The periodic table is a chart that organizes elements by their atomic structure. It is color-coded and assigns each element a unique 1 or 2-letter abbreviation. Other elemental information includes atomic weight and atomic number. You can find a periodic table online or in a chemistry book.
How to find the atomic number of an element?
Locate the element’s atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.
What is the atomic number of an atom?
The atomic number is the proton. The number of electrons in an atom is always the same as the number of protons in the nucleus, unless it is an isotope. The neutron is the atomic mass minus the atomic number.
Why is an ion positive?
Although the number of protons in the atom remains the same, the number of electrons is altered in an ion. Because an electron has a negative charge, when you remove electrons, the ion becomes positive.
Why does an ion become positive when you remove electrons?
Because an electron has a negative charge, when you remove electrons, the ion becomes positive. When you add more electrons, the ion becomes negative.
What are the three groups of elements?
Find your element on the periodic table. The table orders elements by atomic number and separates them into three main groups: metals, non-metals, and metalloids (semi-metals). Further elemental groupings include alkali metals, halogens, and noble gases.
Which type of charge is positively charged?
Protons are positively charged, electrons are negatively charged, and neutrons have no (neutral) charge.
