Question 24

Describe the group 1 elements

Answer 24

Known as alkali metals that are normally very soft and very reactive. react very vigorously with water to produce hydrogen gas and metal hydroxides. React vigorously with chlorine gas to produce metal chloride salts and react with oxygen to form metal oxide
