@@**Where are the alkali metals?**@@

The elements in group 1, on the left of the periodic table, are called the alkali metals.

%%**Why are they called the ‘alkali metals’?**%%

These metals when react with water form alkaline compounds

$**Name 4 properties of Group 1 elements:**$

1) They are soft metals

2) They are metals with low densities.

3) They have low melting points.

4) They are good conductors of electricity and heat.
