Bond Formation

Ionic Bonding involves:

• The transfer of protons

• The transfer of neutrons

• The transfer of electrons

• None Of the above

Covalent compounds:

• Share electrons

• Transfer electrons

• Neither

What is a valence electron?

• an electron that is found in the outermost shell of an atom.

• an electron found in the innermost shell of an atom.

• an electron found in the middle shell.

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.
