Answer:
physical properties: soft & can easily be cut by a knife, has low melting & boiling points, low density and conducts electricity, as they have mobile (delocalised) ions
chemical properties: loses 1 valence electron to from 1+ cations, forms ionic compounds with similar formulas (e.g. sodium chloride is a salt), very reactive metals & strong reducing agents (lithium is the least reactive and francium is the most reactive), reacts with water to form alkali and hydrogen (products of reaction)
