Question

What are the group one elements called?

Answer 1

Alkali Metals:

• The basic or alkaline quality of their metal hydroxides is referred to as 'alkali' in general.
• The compounds are known as alkali metals because when they react with water, they frequently produce alkalies, which are strong bases capable of neutralising acids.
• Water reacts with alkali metals to generate basic hydroxides, which release hydrogen.
• From Lithium $\left(\mathrm{Li}\right)$ to Caesium $\left(\mathrm{Cs}\right)$, the metal's reaction is exothermic, and the enthalpy rises.
• During the process, the alkali metal floats on the water.
• Sodium and potassium have a lower density than water.

Element presents in the first group:

• Lithium $\left(\mathrm{Li}\right)$
• Sodium $\left(\mathrm{Na}\right)$
• Potassium $\left(\mathrm{K}\right)$
• Rubidium $\left(\mathrm{Rb}\right)$
• Caesium $\left(\mathrm{Cs}\right)$
• Francium $\left(\mathrm{Fr}\right)$
