Question

an atom A has 2K,8L and 3M electron Another atom B has 2K and 6L electrons the formula of compound formed between A and B

Answer 1

Answer:

Al2O3

Explanation:

atom A has 13 electron means its Aluminium. and aluminium has valancy electrons=3

while atom B has 8 means its Oxygen and having valency = 2

final compound is Al2O3

Answer 2

An atom A has 2K, 8L and 3M electron Another atom B has 2K and 6L electrons the formula of compound formed between A and B is $Al_{2}O_{3}$.

Explanation:

Since, it is given that atom A has 2K,8L and 3M electron which means that there are in total 13 electrons present. This shows that element A is aluminium.

On the other hand, it is given that atom B has 2K and 6L electrons which means that there are in total 8 electrons. Hence, element B is oxygen.

So, when both aluminium and oxygen atom chemically combine with each other then the compound formed will be $Al_{2}O_{3}$.
