Question

chemicl properties of group 1

Answer 1

Answer:

Alkali metals are very reactive. Alkali metals, when exposed, can react with oxygen and water vapour in the air. Hence, alkali metals such as lithium, sodium and potassium must be kept in paraffin oil, whereas rubidium and caesium are stored in sealed glass tubes.

Explanation:

The alkali metals are a group of chemical elements in the periodic table with the following physical and chemical properties:

shiny.

soft.

silvery.

highly reactive at standard temperature and pressure.

readily lose their outermost electron to form cations with a charge of +1.

Physical properties of the group 1 elements

are soft (they can be cut with a knife)

have relatively low melting points.
