Which of the following conditions produces an anion?
A
An atom loses one or more neutrons
B
An atom loses one or more electrons
C
An atom gains one or more electrons
D
An atom gains one or more protons
Verified step by step guidance1
Understand what an anion is: an anion is a negatively charged ion, which means it has more electrons than protons.
Recall that electrons carry a negative charge, protons carry a positive charge, and neutrons are neutral (no charge).
Analyze each condition: losing neutrons does not change charge, losing electrons makes the atom positively charged (cation), gaining protons changes the element but also increases positive charge.
Focus on the condition where the atom gains one or more electrons, which increases the negative charge and thus forms an anion.
Conclude that the condition producing an anion is when an atom gains one or more electrons.
