Question 25
F

A neutral atom contains 12 protons and 12 electrons. One electron moves to an orbit farther from the nucleus but stays in the atom. Later, a different electron leaves the atom.

What is the relative charge after each change?

[1]
A

After the first change +1+1+1; after the second +2+2+2

B

After the first change −1-1−1; after the second −2-2−2

C

After the first change 000; after the second +1+1+1

D

After the first change 000; after the second −1-1−1
