8th Grade Bonding Review

Atoms bond for all of the following reasons EXCEPT

• To use more energy

• To use less energy

• To have 8 valence electrons

• To become stable

The attraction an atom has for electrons in a bond is its

• polarity

• ionic

• covalent

• electronegativity

When atoms share electrons UNEQUALLY, the bond is

• polar covalent

• ionic

• completely covalent

• electronegativity

A bond between two non-metals is

• binary ionic

• binary covalent

• polyatomic ionic

A bond between a metal and a non-metal is

• binary ionic

• binary covalent

• polyatomic ionic

A bond between an element and a polyatomic ion (or between two polyatomic ions) is

• binary ionic

• binary covalent

• polyatomic ionic

Which element has the HIGHEST electronegativity?

• sodium

• francium

• oxygen

• fluorine

Which element has the LOWEST electronegativity?

• sodium

• francium

• oxygen

• fluorine

If a bond is made between elements that both have HIGH electronegativity, the bond will be

• ionic

• covalent

• metallic

• All of these

If a bond is made between elements with VERY DIFFERENT electronegativities, the bond will be

• ionic

• covalent

• metallic

• All of these
