⭐How many atoms of an element with atomic number 35 can combine with an atom of an element with atomic number 20? ExplainBEST ANSWER WILL BE MARKED AS BRAINLIEST!

Answer»

Atomic number of element 1=35
:. electronic configuration=2,8,18,7
:. Valence electrons=7
:. valency of element 1= -1

atomic number of element 2=20
:. electronic configuration=2,8,8,2
:. Valence electrons=2
:. valency of element 2= +2

:. according to Criss cross method,
2 ATOMS of element 1 combine with 1 ATOM of element 2 to FORM a stable element.

l hope it helps you....
