Answer:

Answer:

Atomic number = Number of protons = 8

Atomic mass = Number of protons + Number of neutrons = 8 + 10 = 18 u

Valence electrons = 6

Valency of ‘X’ = 8 - 6 = 2

‘X’ should be non-metal because there are six valence electrons hence it will take two more electrons to complete its outermost shell
