Answer 2

Answer:

a) A is most electropositive because it's outer configuration is 4s¹ (it can lose one electron)

b) D is noble gas because it's outer configuration is 3s² 3p6 (complete octet)

C) B is metalloid

d) C (Because it's outer configuration is 2s²2p⁴, it can accept two electrons to attain noble gas configuration)

e) A2C (Valancy of A is 1 and valancy of C is two)

F) B and D (B having configuration 3s²3p⁴ and D having configuration 3s²3p6) both are in third period
