Further explanation
There are two components that accompany an element, the mass number and atomic number
Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons
The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.
Atomic number = number of protons = number of electrons ⇒ neutral number
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Number of Neutrons
In the picture above :
Protons = 5
Neutrons = 5
Both are located in the atomic nucleus (red and blue)
Electrons = 2
Located in the atomic shell
So :
the atomic number = number of protons = 5
the mass number = protons+neutrons = 5+5=10
charge of atom = protons-electrons=5-2=+3
The element with atomic number 5 is Boron
