Answer 2

Element with Valency of 1 and Distribution in the 4th Period

The element that forms an oxide and hydroxide of a basic nature with a valency of 1 and is distributed in the 4th period is Sodium (Na).

Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. It is a basic element and forms oxides and hydroxides of a basic nature.

Characteristics of Sodium

Sodium is highly reactive, and it is an essential element for human health. It plays a crucial role in the regulation of blood pressure and fluid levels in the body. Sodium compounds have various industrial and commercial applications, including the production of glass, paper, and textiles.

Sodium's atomic number is 11, and it is located in period 3 and group 1 of the periodic table. It has a single valence electron, giving it a valency of 1. Sodium is highly abundant in nature and is found in many minerals, including halite (rock salt), soda ash, and brine.

Sodium is also a key component of common salt (sodium chloride), which is essential for the human diet. It is involved in various biological processes and is necessary for the proper functioning of nerves and muscles.
