Write the atomic number, atomic mass, number of protons, electrons and neutrons for the first five elements

The first five elements of the periodic table are: - hydrogen, helium, lithium, beryllium, boron

Explanation:

atomic number - it is represented by the letter Z. It is basically the total number of protons present in each atom's nucleus of that element.

atomic mass - is the mass of a single atom present in the element.

electrons and protons - they are negatively and positively charged particles found in the nucleus of the atom respectively.

neutrons - they have no or zero charge and weigh more than protons.

element | atomic number | atomic mass | electrons | protons | neutrons

hydrogen (H) - 1 | 1.008 | 1 | 1 | 0

helium (He) - 2 | 4.0026 | 2 | 2 | 2

Lithium (Li) - 3 | 6.94 | 3 | 3 | 4

beryllium (Be) - 4 | 9.0122 | 4 | 4 | 5

Boron (B) - 5 | 10.81 | 5 | 5 | 6
