Which type of ion is formed when electrons are lost, and which type is formed when electrons are gained?
A
A cation is formed when electrons are lost, and an anion is formed when electrons are gained.
B
No ions are formed when electrons are gained or lost.
C
An anion is formed when electrons are lost, and a cation is formed when electrons are gained.
D
Both cations and anions are formed when electrons are lost.
검증된 단계별 안내1
Understand that ions are atoms or molecules that have gained or lost electrons, resulting in a net electric charge.
Recall that when an atom loses electrons, it has more protons than electrons, leading to a positive charge. This positively charged ion is called a cation.
Recognize that when an atom gains electrons, it has more electrons than protons, resulting in a negative charge. This negatively charged ion is called an anion.
Therefore, losing electrons forms a cation, and gaining electrons forms an anion.
Use this knowledge to evaluate the answer choices and select the one that correctly states: 'A cation is formed when electrons are lost, and an anion is formed when electrons are gained.'
