The s- Block Elements of the periodic table of elements consists of the 1st 2 groups, the alkali metals & alkaline earth metals + hydrogen & helium.
The d block elements fall between the p block & the s block. They share the common characteristics in which the d sublevel of the atom is being filled
The s- Block Elements or metals such as Na and Ca have s electrons which are easily lost, but the ionization energies of the inner electrons are very high that they are never lost in chemical reactions. Hence the oxidation number of sodium is always +1 & calcium is always +2
In our next blog we shall learn about scale drawing worksheets I hope the above explanation was useful.Keep reading and leave your comments.
