How does shielding effect or Screen effect affects the ionization energy?

How does shielding effect or Screen effect affects the ionization energy? In the case of many electrons, the electrons in the atom can protect the electrons of the valence shell from the pull of the nucleus. This effect is known as shielding effect (also known as screening effect). Shielding effect is just like a protective …

Electronegativity definition- Factors Influence Electronegativity – Chemistry

Key points: Electronegativity is the ability of an atom to attract the shared electron pair towards itself in a covalent bond. The electronegativity increases from left to right in a period. The electronegativity decreases down the group. Factors affecting Electronegativity: The key factors that influence electronegativity are as follow: 1. Atomic size 2. Nuclear charge …
