Answer:
Carbon 12 and carbon 13
Carbon isotope 12 exist as 98.9%
Explanation:
My part of the atom, I'm guessing you are referring to the protons, neutrons, and electrons.
The smallest of these three is the electron.
Oxygen and glucose that’s all I know
Molecular orbital energy is the energy associated with each electron in an atom or molecule.
It is expressed in electron volts (eV) and is determined by the electron's position in the atom or molecule. The molecular orbital energy diagram and fill-in the electrons are given here in each case, the number of valence electrons in the species is determined first; this is followed by the valence molecular orbital diagram for each species.
