Question

Atomic number of beryllium is 4 and that of oxygen is 8. Write down their
electronic configuration and state which is electropositive element and why?​

Answer 1

Explanation:

Be is electropositive because It is a metal

Answer 2

Answer:

Explanation:

Atomic number of Beryllium = 4

Electronic configuration = (2, 2)

Atomic number of Oxygen = 8

Electronic configuration = (2, 6)

Valency of Beryllium is 2,

Valency of Oxygen is = 8 ‒ 6 = 2
