write the electronic configuration of two elements A and B whose atomic numbers are 20 and 17. Write the molecular formula of the compound formed when element A reacts with element B. State whether this compound is acidic,basic or neutral. Give reason to justify your answer.
Answers
Answer:
The element A whose valency is 20 is Calcium and it's electronic configuration is 2,8,8,2 and element B whose valency is 17 is Chlorine and it's electronic configuration is 2,8,7.
The compound formed when element A reacts with element B is Calcium Chloride. It's formula is CaCl2.
Cacl2 is neither acidic nor basic. It's a salt and hence is neutral.
I hope the answer is satisfactory and helpful.
Answer:
of A -k shell-2. of B -- k-2
-l -8. l-8
-m-8. -m-7
-n- 2
A is calcium
B is chlorine
when both react together, they formed clacium chloride.
Ca. +. cl2. ✓. CaCl2
it is neutral because it is a salt formed from the combination of metal and non- metal.
