Intro to Chemical Bonds

Why do all bonds form?

• To fill up the outer shell and become more stable.

• To look cool.

• To become less stable.

• So they don't have to be alone.

How many bonds can Hydrogen make?

• 1

• 2

• 3

• 4

Where are the non-metals located on the periodic table?

• all over

• On the left side of the "staircase"

• On the right side of the "staircase"

Predict the bond that form between Be and F

• Covalent

• Ionic

Answer explanation

These two elements are on opposite sides of the periodic table so they are a metal and non-metal...... a recipe for an ionic bond.
