What is electronegativity How does it vary in group and period?
What is electronegativity How does it vary in group and period? The tendency of an atom to attract the shared pair of electrons towards itself is known as electronegativity. Electronegativity increases across a period while it decreases down a group. Atomic radius increases down the group due to addition of new shell. How does electronegativity […]
