Question

Help pls!!

The table compares the number of electrons in two unknown neutral atoms.
Comparison of Electrons
Atom Number of Electrons
A 10
D 11
Use this information to determine the number of valence electrons in the atoms. Which of the following correctly compares the stability of the two atoms?

A Both are unreactive.
B Both are highly reactive.
C A is unreactive and D is reactive.
D A is reactive and D is unreactive.

Answer 1

Answer: A is unreactive and D is reactive.

Step-by-step explanation:

A is neon, which is a noble gas, and thus unreactive.

D is sodium, which is an alkali metal, and thus highly reactive.
