when a calcium atom forms an ion, it loses two electrons. what is the electrical charge of the calcium ion?\n-2\n-1\n+1\n+2
Answer
Explanation:
Step1: Understand electron - charge relationship
Electrons have a negative charge of - 1 each.
Step2: Calculate the charge of the ion
When calcium loses 2 electrons, the charge change is $-(- 2)=+2$.
Answer:
D. + 2
