Question

Ionization energy generally decreases down a group because as one moves down a group, the outermost electron moves _____ the nucleus and it takes _____ energy to remove it.

Answer 1

Ionization energy generally decreases down a group because as one moves down a group, the outermost electron moves further away from the nucleus and it takes less energy to remove it.

Ionization energy, also known as ionization energy, would be the minimal amount of energy needed to free an isolated gaseous atom's or molecule's least loosely bonded electron.

First ionization energy often drops as you advance down a group on the periodic table. This occurs even though the outermost electron would be typically held less securely and can be removed with less energy since it travels farther away from the nucleus.

Therefore, Ionization energy generally decreases down a group because as one moves down a group, the outermost electron moves further away from the nucleus and it takes less energy to remove it.
