Question

Which of these pairings would

create an octet for each atom?
A. one aluminum atom and one phosphorus atom
B. one sodium atom and sulfur atom
C. one strontium atom and one nitrogen atom
D. one lithium atom and one oxygen atom

Answer 1

A. one aluminum atom and one phosphorus atom.

Step-by-step explanation:

One aluminum atom and one phosphorus atom will create an octet for each atom because one aluminum atom have 3 valence electrons in its outermost shell and one phosphorus atom have 5 valence electrons in ar aits outermost shell. And, 3 + 5 = 8, which is the number of electrons needed in the outermost shell of the atom of an element for it to be stable.
