Multiple Choice

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 non-metal atoms.

• two non-metal atoms are attracted to each other by opposite charges.

Multiple Choice

• gain
• lose

Multiple Choice

In an ionic compound, the total positive charge of all the positive ions ___________ the total negative charge of all the negative ions.

• equals
• is more than

Multiple Choice

Why do bonds form?

• To fill the valence shell of electrons for the elements involved
• to release energy stored in the bonds
• because whenever you mix two chemicals, there will be a reaction
• because of attraction

Multiple Choice

What type of bond is present when electrons are freely shared between metal atoms?

• Metallic
• Ionic
• Covalent
• Hippie

Multiple Choice

Why are metals good conductors of electricity?

• The electric current can easily travel along the surface of the metal because it is smooth.

• A negative charge can easily push the sea of electrons in one direction, making a current.

• Metals attract electricity.
