WebIn general, electronegativity increases from left to right across a period in the periodic table and decreases down a group. Thus, the nonmetals, which lie in the upper right, tend to … WebWhat is Electronegativity. Electronegativity is the tendency of an atom to attract a pair of electrons in a chemical bond. It is caused by the attractive electrostatic force between the positively charged nucleus and the negatively charged electrons. The more electronegative an atom is, the higher will be the attractive force [1-4].
