Electronegativity - Definition, Periodic Trends, Effect on ...
byjus.com › chemistry › electronegativityAs we move across a period from left to right the nuclear charge increases and the atomic size decreases, therefore the value of electronegativity increases across a period in the modern periodic table. For example, the electronegativity trend across period 3 in the periodic table is depicted below. There is an increase in the atomic number as we move down the group in the modern periodic table. The nuclear charge also increases but the effect of the increase in nuclear charge is overcome by ...
