Question

vocabulary: which chemical bonds hold atoms together? a chemical bond is a strong attraction between two or more atoms. can you identify the properties of different types of chemical bonds? drag the terms on the left to the appropriate blanks on the right to complete the sentences. single double ions ionic covalent nonpolar hydrogen polar 1. a(n) bond forms when one atom gives up one or more electrons to another atom. 2. atoms or molecules with a net electric charge due to the loss or gain of one or more electrons are 3. a(n) bond involves the sharing of electron pairs between atoms, also known as a molecular bond. 4. when one pair of electrons is shared between two atoms, a bond is formed. 5. when two pairs of electrons are shared between two atoms, a bond is formed. 6. a bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms. as a result, one end of the molecule has a slightly negative charge and the other a slightly positive charge. 7. atoms involved in a bond equally share electrons; there is no charge separation to the molecule. 8. a weak bond called a bond results from an attraction between a slightly positive region in a molecule and a slightly negative region in the same or a different molecule.

Explanation:

1. Ionic bonds form by electron - transfer.
2. Ions are charged atoms/molecules from electron gain/loss.
3. Covalent bonds are from electron - pair sharing.
4. A single covalent bond is one electron - pair sharing.
5. A double covalent bond is two electron - pair sharing.
6. Polar bonds have unequal electron sharing.
7. Nonpolar bonds have equal electron sharing.
8. Hydrogen bonds are weak intermolecular attractions.

Answer:

1. ionic
2. ions
3. covalent
4. single
5. double
6. polar
7. nonpolar
8. hydrogen
