Question

Alkali metals belong to S-block elements. Why?

Answer 1

Answer:

S-block elements are the elements with valence electrons in the s orbital.Elements in column 1 (the alkali metals) always lose their one valence electron to form a +1 ion. Elements in column 2 (the alkaline earth metals) always lose their valence electrons to form +2 ions.

Answer 2

Answer:

Hii...!

The s-block elements having only one electron in their s-orbital are called group one or alkali metals whereas the s block elements having two electrons filling their s-orbital are called group two or alkaline earth metals.

Exactly, Alkali also s-block element because, it's eligible to be as s-block element.

------------------------------------

The elements in column 1, known collectively as the alkali metals (except hydrogen), always lose their one valence electron to make a +1 ion.

s-block elements are the elements found in Group 1 and Group 2 on the periodic table. Group 1 are the alkali metals which have one valence electron. They have low ionization energies which makes them very reactive. Group 2 is the alkali earth metals which have two valence electrons, filling their s sub-level.

Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). Are examples in the first group of s block elements.
