Explanation:

The symbol δ+ (delta plus) is used to denote a partial positive charge. This occurs when an atom in a molecule has a slightly lower electron density compared to other atoms in the molecule, often due to differences in electronegativity. For example, in a polar covalent bond like in H - Cl, the Cl is more electronegative, so the H has a δ+ charge.

The symbol δ− (delta minus) is used to denote a partial negative charge. This happens when an atom has a slightly higher electron density. In the H - Cl example, the Cl atom has a δ− charge because it attracts the shared electrons more strongly than H.

Answer:

partial positive, partial negative
