Chemical bonding

Why do atoms bond?

• They typically don't bond

• To add or take away energy levels

• To have a full valance shell.

• To have a full inner shell

Which bond does this picture best represent?

• Metallic bond

• ionic bond

• covalent bond

• James Bond

Predict the bond between Mg and Cl

• covalent

• ionic

• metallic

• none of the above

CaCl₂ is an example of what type of bond?

• Covalent

• Metallic

• Ionic

What elements generally make a covalent bond?

• metal and nonmetal
• 2 nonmetals
• metal
• none of the above

In chemical compounds, covalent bonds form when

• the electronegativity difference between two atoms is very large.
• electrons are completely transferred between two metals.
• pairs of electrons are shared between two nonmetal atoms.
• two nonmetal atoms are attracted to each other by opposite charges.
