Which of the following best describes the formation of a cation?
A
Loss of electrons
B
Gain of neutrons
C
Loss of protons
D
Gain of electrons
Verified step by step guidance1
Understand that a cation is a positively charged ion.
Recall that ions form when atoms gain or lose electrons, not protons or neutrons.
Recognize that gaining electrons adds negative charge, resulting in an anion (negative ion), not a cation.
Recognize that losing electrons removes negative charge, leaving a net positive charge, which forms a cation.
Therefore, the formation of a cation is best described as the loss of electrons.
