Answer:
Total Energy of the electrons
Explanation:
An atom in an excited state is when the total energy of electrons can be lowered by transferring molecule(s) over to different orbitals. in an excited state atom, not all electrons are at the lowest energy levels
I would say B.
Explanation: Peer review improves the quality of research papers.
If the density is higher than water than the object will sink
I think that is called a Metamorphic rock.
The total mass would be 142.05 g/mol. Since sodium is 22.99 g/mol and there are 2 sodium atoms, it would be 45.98 g/mol. Divide 45.98 by 142.05 and you get 32.37%
