In general, none.
Outer electrons are the electrons that are borrowed or stolen in a reaction. Because a non-metal has a negative oxidation number, it will borrow electrons from a metal to complete its outer shell. Metals have positive oxidation numbers and tend to lose electrons in reactions.

A covalent bond is a type of bond where electrons are shared between atoms rather than transferred. In this bond, atoms achieve stability by sharing one or more pairs of electrons.
In general, electrons further from the nucleus will have more energy than electrons closer to the nucleus.
Ionic bond. In an ionic bond, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions which are then attracted to each other, creating a bond.
A semiconductor typically has fewer free electrons than a conductor but more than an insulator. The number of free electrons in a semiconductor can vary based on factors like doping and temperature, but in general, it is on the order of 10^15 to 10^19 free electrons per cubic centimeter.
The protons in an atom have a positive charge and the electrons in an atom have a negative charge and these balance each other. Neutrons have no charge so they do not factor into it. It would be like adding positive 4(Protons) and negative 4(Electrons). -4+4=0 The zero represents your "no overall charge".
In general, yes, we normally think of the movement of electrons (electron flow) as electric current.

English uses many borrowed words too many to list here. But the following are some borrowed words: Hawaiian - ukulele, hula Malay - bamboo, gong Mandarin - kowtow, typhoon Norwegian - walrus, ski welsh - corgi, maggot
In a covalent bond, electrons are shared between two atoms and are located in the overlapping region of the orbitals of the bonded atoms. This shared electron density creates a bond that holds the atoms together.
A borrowed word is one that originated in another language, but now is used in English. For instance, how many US citizens don't know what a taco is? The word taco is borrowed from Spanish. We have algebra classes. The word algebra is from Arabic. There are many such examples. See the website below for more.
