A.
If an atom loses one or more electrons, the atom becomes a(n)
- positive ion.
- negative ion.
- different element.
- isotope.
B.
Which of the following refers to a charged atom that forms when the numbers of electrons and protons are not equal?
- an ion
- electron
- isotope
- proton
C.
D.

- add an electron
- subtract an electron
- subtract a proton
E.
Which of the following correctly describes part of the underlying nature of negatively-charged anions?
- The atom has more electrons than protons.
- The atom has more protons than electrons.
