polar
In a polar covalent bond, electrons are unequally shared between atoms, resulting in a partial negative charge on one atom and a partial positive charge on the other. This unequal sharing causes a dipole moment, creating a polarity in the molecule.
The movement of electrons is electrical energy.

An appositive phrase is a noun or noun phrase that renames or explains another noun in the sentence. It provides additional information about the noun it follows. Appositive phrases are usually set off by commas.
Valence electrons are the outermost electrons in an atom that are involved in chemical bonding. They determine the reactivity and chemical properties of an element.

Electron orbits are quantized, meaning they can only exist at specific energy levels called "shells". These shells are increasing in energy from the innermost to the outermost, and electrons can jump between them by absorbing or emitting energy.
