Question

Why are potassium and sodium in the same Group of the periodic table?

Answer 1

Explanation:

• Because potassium and sodium have same chemical properties .

• Potassium and sodium have one valence electron because they can lose electrons easily to form ${a}^{+}$ ion.

• Potassium and sodium react with water to form hydrogen gas and hydrogen ion .

Answer 2

POTASSIUM AND SODIUM -

Potassium and Sodium are placed in the same group of the periodic table because of the following physical and chemical properties -

• The electronic configuration of the elements shows that the presence of one electron in the valence shell.
• Both elements lose an electron to form a cation.
• The elements have low ionization and low electron affinity.
• The elements are present on the left side of the periodic and are metals.
• They react with acid to release hydrogen gas.
• Both the elements form an ionic bond by the release of an electron.
