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

Ionic bonding is between a

• nonmetal and nonmetal

• metal and nonmetal

• metal and metal

• Depends on the situation

Covalent bonding is between a

• nonmetal and nonmetal

• metal and nonmetal

• metal and metal

• It depends on the situation

What happens when magnesium loses 2 electrons?

• It stabilizes to a net charge of 0

• It turns into an atom

• It becomes negatively charged

• It becomes positively charged

Predict the bond between Mg and Cl

• none of the above

CaCl₂ is an example of what type of bond?

• Covalent

• Metallic

• Ionic

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.
