IPC Unit 4 Lesson 2

1. a type of chemical bond formed when two atoms share their valence electrons to form a compound 2. chemicals formed when two of the same atoms share electrons 3. bonds formed when two pairs of valence electrons are shared between two atoms 4. bonds formed when atoms equally share electrons with one another 5. bonds formed when atoms do not equally share electrons with one another 6. molecules that have both a slightly negative and positive end while overall charge remains neutral 7. covalent bonds formed when one pair of valence electrons is used to bond two atoms 8. covalent bonds formed when three pairs of valence electrons are used to bond two atoms

1. covalent bond 2. diatomic molecules 3. double bonds 4. nonpolar covalent bonds 5. polar covalent bonds 6. polar molecules 7. single bonds 8. triple bonds

Covalent bonds only form between atoms of metals.

False; Covalent bonds only form between atoms of nonmetals.

What makes a compound polar?

Polar covalent bonds are formed when atoms share electrons, but this sharing is unequal due to differences in charge of the atoms.

Rather than holding tightly to their valence electrons, some atoms take the easier route (less energy) of sharing electrons to achieve chemical stability.

True

A double bond that has medium strength and medium length has _________ stability.

medium

Is the compound labeled "A" polar or nonpolar?

nonpolar

Is the compound labeled "B" polar or nonpolar?

polar

A triple bond that has low stability and strong strength has ______ length.

short

A single bond that has high stability and long length has _________ strength.

weak
