Unit 6 - Bonding Atoms

Why do atoms bond?

• Because they want to

• To transfer or share electrons

• They don't

• To make more atoms

What keeps atoms bonded together?

• electrons attracting to each other

• Gravity

• Ionic and Covalent bonds

• Chemical Reactions

What elements make up Ionic bonds?

• Earth metals and metalloids

• Gasses and noble gasses

• Non-metals and metals

• Metals and Metalloids

How do atoms turn into ions?

• When they come in contact with protons

• It is very rare to happen

• When they combine with other atoms

• When they gain or lose an electron

What elements make up a covalent bond?

• Metals and metals

• Metals and noble gasses

• Non-metals and Non-metals

What is a covalent bond?

• When bonded atoms have lower total energy

• When two atoms bond together

• I don't know

• Higher energy makes them bond easier
