element with atomic no. 12 and atomic no. 38 will have chemical properties same as calcium. this is due to the fact that they have valency same as calcium and also lie in the same group.

We know
Electronic configuration (e.c) of Ca is 2 8 8 2
i.e valency of Ca is 2
Atomic no. of elements surrounding Ca are 12 19 21 and38
e.c of Z=12 is 2 8 2 i.e valency is 2
e.c of Z=19 is 2 8 8 1 valency is 1
Z=21 valency is 1
Z=38 valency is 2
since the valency of elements having Z=12 and 38 match with Ca .
therefore their chemical properties will also match.
pls mark the brainliest i m in a hurry plss
