Explanation:
The periodic table arranges elements based on their atomic numbers in a systematic fashion.
There are about 110 elements on the periodic table with each of them having their unique atomic numbers.
On periodic table, most atoms are designated as:
ₓⁿT
T is the symbol of the atom
X is the atomic number of the atom
n is the mass number
Atomic number is the number of protons in atoms in an element. Protons are the positively charged particles.
Mass number is the number of protons and neutrons in an atom. Both protons and neutrons are in the nucleus of an atom.
Atomic number = number of protons = number of electrons
Mass number = number of protons + number of neutrons
Number of neutrons = mass number - number of protons
Number of neutrons = mass number - atomic number
