Two (2) electrons can be held in the first orbit.
The maximum number of electrons that can be held in the third orbit of an atom is 18. This is based on the formula 2n^2, where n is the principal quantum number of the orbit. For the third orbit (n=3), the maximum number of electrons is 2 x 3^2 = 18.
About 14 or less sometimes it changes just kidding about 14 bye thi was Nyahrules
2 electrons maximum. 1s2
Between electrons and the atomic nucleus a repulsion exist.
The second energy level (orbit) can hold 8 electrons.
What happens to the high-energy electrons held by NADH if there is no oxygen present?
8
Because they are the outer electrons in an atom and they orbit around the nucleus. But you should ask a scientist this question. NOT put it on ask.com. OR look it up on google.com. it is very likely that you will find something there.
the max is 2 for the first orbitthe max is 8 for the second orbitthe max is 8 for the thrid orbit too.User:HeleneM5500:06, 4 Sep 2009 (UTC)Electrons follow paths called orbits, shells, or levels. Each shell can hold a specific maximum number of electrons. Each electron possesses a definite amount of energy. The radius of the orbit depends on the amount of energy that electron has & on the attractive force the nucleus has for that electron. Bohr model of the atom (with main energy levels identified by number: 1 --> 7Shell #1 closest to nucleus can hold a maximum of 2 each.Shell #2 next shell outward can hold a maximum of 8 each.Shell #3 next shell outward for elements Z = 1 --> 20, this shell can hold a maximum of 8 e-, for all others a maximum of 18 each.
The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)
If you are mentioning about sticking two hydrogen atoms with one oxygen atom, then it's water. Other than that, oxygen and hydrogen are not together, unless they are water, hydrogen peroxide, or some other compound with an -OH group. In such compounds the hydrogen and oxygen are held together by covalent bonds, the sharing of electrons.
