In chemistry, the s-block element forms an important group of elements. They have an electronic configuration in such a manner that the number of electrons is either 1 or 2 in their outermost shell. The s-block element includes elements found in Group 1 and Group 2 in the periodic table. The element in group 1 has 1 valence electron which makes them very reactive, as they only need 1 electron for stabilization, while elements in group 2 have 2 electrons in the outermost shell, which makes them less reactive than group 1. Due to special configuration of He (which belong to group 8th element), this element is also included in the s-block element.
We at Byju’s provides students to study the s-Block Elements Class 11 Notes where they can get every detail about the elements in s-block, their properties and many more. As this topics forms one of the important topic in chemistry, thus the provided notes can be very helpful for the students to excel in their chemistry paper.
