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
