QB SOLUTIONS CLASS 11 CHEMISTRY
Periodic table
any two characteristics of s block elements
They are soft metals, possess low melting and boiling points, have the largest atomic radii in their corresponding periods and are good conductors of heat and electricity.
They have low values of ionization energies and are hence highly electropositive.
define ionization energy and electronegativity
Ionization Energy and Electronegativity are the inverse of each other. Electronegativity is an atom's tendency to attract an electron. In contrast, the ionization energy is the energy needed to remove an electron from an atom.
1s2 2s2 2p1 is the electronic configuration of Boron
1s2 2s1 is the electronic configuration of lithium
