An ion is:

• the same thing as an electron

• an atom without any neutrons

• electrons in motion.

• an atom with an electrical charge

What is electromagnetism?

• the spectrum of waves

• radiation

• a form of energy

• All of these answers!

The Periodic Table shows how​ ​ (a)   relate to each other.

• elements
• molecules
• atoms
• minerals
• bananas

Organize these options into the right categories

Groups:

(a) True

,

(b) False

• Atoms usually have equal amounts of protons and electrons

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

• All atoms have eight electrons in their outer shell.

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

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

• Sounds travel better through gases than they do through solids

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?

Explain the difference between potential and kinetic energy.

In the Periodic Table, what do the rows tell us about the elements?
