Question

two elements having
atomic number
13 and 8 what will be
the
formula
of the compound formed by them​

Answer 1

Answer:

ANSWER

Two elements A and B contain 13 and 8 protons respectively. They will have 3 and 6 valence electrons respectively and will form A

3+

and B

2−

ion respectively.

The molcular formula of the compound between A and B will be A

2

B

3

.

The atomic mass of A =13+14=27

The atomic mass of B 8+8=16

The formula unit mass for the compound between A and B unit would be 2(27)+3(16)=102

Hence, the option (C) is the correct answer.
