What happens to electrons when chemicals bond?

Answer 1

The electrons are shared between the two chemicals. Each chemical (element) wants a stable octet, so you must make sure both chemicals in the compound have eight valence electrons. Each chemical is connected by a line (bond) which represents two electrons, and you must draw the remaining electrons needed as either lone pairs or more bonds. You determine how many electrons you need in the entire diagram by finding the number of valence electrons for the first chemical and adding it to the number of valence electrons for the second chemical, and so on. If there is a sub number next to the chemical, you need to multiply the number of electrons for that one element times the sub number before adding it to the number of valence electrons for the other chemicals. You must make sure that your diagram has that number of dots/lines in it exactly, no more or no less.

Answer 2

When chemicals bond, electrons are shared, transferred, or attracted in order to achieve a stable electron configuration. This can result in the formation of covalent bonds through electron sharing, ionic bonds through electron transfer, or metallic bonds through electron delocalization. The movement of electrons allows atoms to achieve a more stable and lower energy state.

Answer 3

An electron is either shared or transferred between atoms when chemicals bond. The goal of covalent bonds is to achieve stability by sharing electrons among the atoms. In ionic bonds, electrons are transferred from one atom to another, forming positively and negatively charged ions.
