Ionic bonds and Naming

Most atoms have no net charge because they have....

• an equal number of charged and non-charged particles
• neutrons in their nuclei
• an equal number of electrons and protons
• an equal number of neutrons and protons

What is an ion?

• An atom that has lost or gained protons
• An atom that has lost or gained neutrons
• An atom that has lost or gained electrons
• An atom with a charge of zero

If an atom loses electrons when forming an ion, the charge will be:

• positive
• negative
• neutral

If I gain electrons I become

• Positive because I've added to my atom
• negative because I've added electrons
• same because i'm balanced
• equal because now I have electrons
