Can the exact location of an electron within an atom be determined? What can you know about an electron location?

The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don't have a definite position, and direction of motion, at the same time! ... We know the direction of motion.

Explanation:

Can we determine the exact location of an electron? No, since the electron is always in motion, it is impossible to tell the exact location. The best that scientists can do is determine the chance of finding an electron in a certain place within an atom.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
