Electron affinity from top to bottom
WebApr 1, 2024 · Electronegativity increases as a result of increase in protons and when there is more electron pull. As, the size of an element decreases, the valence electrons are attracted near to the nucleus. Therefore, there is increase in attraction between shared electron and nucleus. WebIt is considered a measure of the tendency of an atom or ion to surrender an electron or the strength of the electron binding. The greater the ionization energy, the more difficult it is to remove an electron. The ionization energy may be an indicator of the reactivity of an element. Elements with a low ionization energy tend to be reducing ...
Electron affinity from top to bottom
Did you know?
WebWhen looking at the periodic table the atomic radius increases from top to bottom, moving down a column; therefore, the electron affinity increases from the bottom to the top of the column. Nuclear charge also affects electron affinity. The nuclear charge is also known as the atomic number, which is the same as the number of protons. Webelectron affinity, in chemistry, the amount of energy liberated when an electron is added to a neutral atom to form a negatively charged ion. The electron affinities of atoms are …
