Question

among the following statements identify the correct set of statements
1) size of the Be is smaller than Mg. 2) ionization energy of Be is greater than Ai
3) both Be and Ai form covalent compounds readily.
4) both Be and Ai does not react with nitrogen​

Answer 1

Answer:

1 and 2 are correct answer

Answer 2

we have to check among the following statements which is correct set of statements.

solution : we know in Morden periodic table, size increases when we go down the ground.

so, size of Be is smaller than that of Mg is correct.

configuration of Be = 1s², 2s²

configuration of Al = 1s², 2s², 2p⁶, 3s², 3p¹

definitely it is clear that electron remove from outermost orbit of Al is more easier than that of Be.

so, Ionisation energy of Be is greater than that of Al.

both Be and Al form covalent compounds.

reaction with nitrogen of Be or Al gives nitride

Therefore a, b and c are correct set of statements.

so the correct choice is option (1) a , b, c
