An ion is:

• the same thing as an electron

• an atom without any neutrons

• electrons in motion.

• an atom with an electrical charge

• molecules
• atoms
• minerals
• bananas

Organize these options into the right categories

Groups:

,

(b) False

• When an atom has more electrons than protons, it has a negative charge

• Atoms usually have equal amounts of protons and electrons

• All atoms have eight electrons in their outer shell.

• Sounds travel better through gases than they do through solids

• Friction causes protons to move from one atom to another.

• Pushing a pen off a desk converts potential energy to kinetic energy

What is electricity?

What does it mean to say that opposites attract when you are talking about atoms?

What happens when a magnet is placed near a copper wire?
