Question

A potassium atom (atomic number 19) loses an electron while forming a bond with another atom. which best describes the potassium ion that forms?

a. it is a negative ion that has one less valence electron than a neutral potassium atom.
b. it is a negative ion that has one more valence electron than a neutral potassium atom.
c. it is a positive ion that has one less valence electron than a neutral potassium atom.
d. it is a positive ion that has one more valence electron than a neutral potassium atom.

Answer 1

c

Answer 2

C) it is a positive ion that has one less valence electron than a neutral potassium atom.

That is because when K loses an electron the charge of it goes from 0 to +1.
