when an oxygen atom forms an ion, it gains two electrons. what is the electrical charge of the oxygen ion?\n-2\n-1\n+1\n+2
Answer
Answer:
A. -2
Explanation:
Step1: Understand electron - charge relationship
An electron has a charge of - 1.
Step2: Calculate ion charge
Oxygen gains 2 electrons. So charge is $2\times(-1)= - 2$.
