What happens to the high-energy electrons held by NADH if there is no oxygen present?
the NADH will not oxidize to give NAD+ and H+, so electrons will still held there.

Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
An oxygen atom has two valence electrons.
Oxygen has 6 core electrons.
If you think of it in terms of time, the electrons always spend more on the oxygen. This creates polar bonds, and as the molecule is not symmetrical, it means that the whole molecule is polar.

They form covalent bonds.
They form covalent bonds.
Oxygen, atomic number 8 has 8 electrons. These are all outside the nucleus. So the answer is eight.
there are 8 electrons in an oxygen atom, equal to the number of protons. there are 6 valence electrons though, give or take because they constantly switch
electrons in O16 is 16 while neutrons is 32
Oxide is the ion form of oxygen. It forms when an oxygen atom gains an extra two electrons. So an oxide ion would become an oxygen atom by losing two electrons.
A loss of electrons occur, an oxidation reaction.

Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-
