1. a( 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( 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.

1. Anionic 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 ions.

3. A_covalent__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 single bond is formed. 5. When two pairs of electrons are shared between two atoms, a double bond is formed. 6. A polar covalent 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 nonpolar covalent bond equally share electrons; there is no charge separation to the molecule. 8. A weak bond called a van der waals 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
