Hey mate here is your answer

Sodiun is a monovalent element. Physically it is a metal. Belongs to 1st group of periodic table. Symbol- Na. (Derived from Natrium - a Latin word)

This group elements are known as Alkali metals. Because they form strong bases when react with hydroxide (OH) groups.

(Alkali- a substance that forms a salt when mixed with an acid.)

Example: NaOH., KOH,

When you see the electronic configuration of sodium 1S^2 ,2S^2, 2P^6,3S^1.

The no of Valence electrons are 1.

Inorder to attain stability(octet /noble gas configuration) it needs to gain 7 electrons or loose 1 electron. The latter is possible. Hence it will loose 1 electron.

The term”monovalent” indicates the no.of electrons present in Valence shell i.e. outermost shell of an element.

Note:1- not only sodium but all the 1st group elements are known as monovalent elements. 2-The Valence of electrons increases from left to right in periodic table which indicates the no.of electrons present in outermost shell.

Hope this answer will help you!!

sodium is monovalent because it ha only one electron in its outermost shell.
