Question

Составьте электронную формулу химического элемента% 11 и определите ее основные положения элемента в Периодической системе и его возможную валентность.

Answer 1

Элемент11- это натрий (Na) Натрий-элемент I основного группы, 3-периода Валентность-всегда 1

Answer 2

Chemical Element and its Electronic Configuration

The chemical element with atomic number 11 is sodium (Na). Its electronic configuration is 1s^2 2s^2 2p^6 3s^1.

Position in the Periodic Table and Possible Valency

Sodium is located in period 3 and group 1 (IA) of the periodic table. It belongs to the alkali metal group. Its possible valency is +1.

Sodium's electronic configuration is [Ne] 3s^1, and it has one electron in its outermost shell. This makes it highly reactive, and it readily loses this electron to form a sodium ion with a charge of +1. Therefore, its possible valency is +1
