Chemical Bonding

What elements generally make an ionic bond?

• metal and nonmetal
• 2 or more 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.

When forming an ionic bond, a metal atom

• Gains electrons to form a cation
• Loses electrons to form a cation
• Gains electrons to form an anion
• Loses electrons to form an anion

O + O

• Ionic 
• Polar Covalent
• Metallic
• Nonpolar Covalent

Predict the bond that will form between Be and F.

• Ionic
• Polar Covalent
• Metallic
• Nonpolar Covalent

Ionic Bonding involves...

• The transfer of protons
• The transfer of nuetrons 
• The transfer of electrons
• None Of the above

What is the basis of a metallic bond?

• the attraction of neutral metal atoms.
• the attraction between protons and neutrons.
• the attraction between positive metal ions and interlocking electrons.
• the attraction between positive metal ions and free floating electrons.

What does malleable mean?
