What does "malleable" mean when describing a metal?

Malleable means a metal can be hammered or pressed into different shapes without breaking or shattering.

Metals are described as ______ because they can be drawn into thin wires.

Metals are described as ductile because they can be drawn into thin wires.

Metals can conduct electricity because they contain delocalised / mobile electrons that are free to move through the structure and carry charge.

When magnesium is heated and reacts with steam, it produces magnesium oxide and hydrogen.

False. Only the most reactive metals (potassium, sodium and calcium) react with cold water to produce a metal hydroxide and hydrogen gas.

When zinc reacts with dilute hydrochloric acid, it produces zinc chloride and hydrogen gas.

Potassium, sodium and calcium react with cold water to form a metal hydroxide and hydrogen gas.
