Question

If the number of electrons in an atom is 8 and number of protons is also 8, then
i)what is the atomic number of the atom
ii)what is the charge on the atom​

Answer 1

Answer:

We know that,

No. of electrons (e) = No. of protons (p) = Atomic number (Z)

(i) No. of electrons = 8

Therefore, Atomic number = 8

(ii) The number of protons is equal to the number of electrons. So the atom will be neutral.

Answer 2

Answer:

(i) Atomic number

= Number of Protons = 8

(ii) The charge of the atom is zero, as total number of positive charge is equal to total number of negative charge.

Number of Protons = Number of Electrons

8 = 8
