Answer to Question #134605 in General Chemistry for Kabibe Alexander

Question

Metals and non-metals exhibit different physical and chemical properties. State TWO differences of metals and non-metals for each of the following properties.
(i) Physical Properties
(ii) Chemical Properties

Differences in Physical Properties:
1.
2.

Differences in Chemical Properties:
1.
2.

Answer 1

Differences in Physical Properties:

1. Most of the metals conduct heat and electricity well. Nonmetals are usually poor conductors.
2. Metals are mostly malleable and ductile. Nonmetals tend to be brittle in their solid state.

Differences in Chemical Properties:

1. Metals usually donate their electrons during chemical reactions and form cations. Nonmetals are more electronegative and in ionic compounds they are present as anions (accept electrons).
2. Metals form mostly basic or amphoteric oxides, while oxides of nonmetals are either acidic or neutral.
