Which of the following best describes a cation?
A
A molecule composed of two or more atoms bonded together.
B
A neutral atom with equal numbers of protons and electrons.
C
An ion with a negative charge formed by the gain of one or more electrons.
D
An ion with a positive charge formed by the loss of one or more electrons.
Verified step by step guidance1
Understand that a cation is a type of ion, which means it is an atom or molecule that has gained or lost electrons and thus carries a charge.
Recall that electrons carry a negative charge, so when an atom loses one or more electrons, it has more protons than electrons, resulting in a positive charge.
Recognize that a cation is specifically an ion with a positive charge formed by the loss of electrons.
Compare this to an anion, which is an ion with a negative charge formed by the gain of electrons.
Therefore, the best description of a cation is: 'An ion with a positive charge formed by the loss of one or more electrons.'
