Q

What is a group in the periodic table

A

A group is a column of elements in the periodic table of the chemical elements. The columns, called groups, contain elements with similar chemical behaviours.

Q

Alkali metals

A

Alkali metals are group 1 that melting point decrease from top to bottom. They are very reactive as they only have one electron in their outer shell. They get more reactive as you go down.

Q

Noble gasses

A

Group 0 have very low melting points that decrease going down. They glow brightly when high-voltage electricity passes them. They are unreactive. They come from the atmosphere mixed with other gasses and we use distillation to separate them.

Q

The transition metals

A

The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table. They have high melting points and densities, and are strong and hard. They form coloured compounds and act as catalysts.
