Question

The atomic number of oxygen and sulphur are 8 and 16 respectively. What will be the number of electrons in these ?




hlp me please​

Answer 1

Explanation:

Atomic number = number of protons= 16

Mass number = number of protons + number of neutrons

So mass number of sulphur = 32

Answer 2

Answer:

Number of Protons = 8

Number of Electrons = 8

Number of neutrons = 7

Atomic Number = Number of electrons = Number of protons

(i) The atomic number is equal to the number of protons. Therefore, the atomic number of the atom is 8.

(ii) Since the number of both electrons and protons is equal, therefore, the charge on the atom is 0.
