Answer 2

Answer: Sodium ( alkali metal)

Explanation: Being in the first column, sodium is a member of the alkali metal family with potassium (K) and lithium (Li). Sodium's big claim to fame is that it's one of two elements in your table salt. When bonded to chlorine (Cl), the two elements make sodium chloride (NaCl). Sodium is also used as a salt in many fertilizers.

Even though humans have been using sodium for thousands of years, it was not isolated until 1807 by a chemist named Davy. When you purify sodium, you actually wind up with a silvery bright metal that is quite soft and malleable. Sodium is one of the few metals that will float when it is placed in water (H2O). Sodium's atomic mass is less that water's atomic mass of 18 amu.
