Why do cations have a positive charge?
A
Because they have lost one or more electrons
B
Because they have gained one or more electrons
C
Because they have more electrons than protons
D
Because they have more neutrons than protons
Verified step by step guidance1
Understand that atoms are made up of protons, neutrons, and electrons. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral.
Recognize that the overall charge of an atom depends on the balance between the number of protons and electrons.
Know that a cation is an ion with a positive charge, which means it has more protons than electrons.
Realize that a cation forms when an atom loses one or more electrons, reducing the number of negatively charged particles.
Therefore, the positive charge of a cation arises because it has lost electrons, making the number of protons greater than the number of electrons.
