Electrons hold different positions around the nucleus, and they can be in different places at different times. Their positions might be said to be random in that light. It is the energy level of an electron that is fixed. Each electron has a specified Fermi energy level in which it hangs out. This is not a physical location, but is a quantum mechanical characteristic. That's why we say that the electrons occupy an electron cloud. They are not in any specific location, but occupy an area of probability in the electron cloud. The electrons are in motion, and go here and there, but always have the same net energy.

∙ 11y agoIn the Bohr model of the atom, yes, they orbit around the nucleus made up of protons and neutrons.
In more recent quantum mechanical models they do not circle the nucleus, but are in certain energy levels called orbitals.

∙ 15y agoYes. The orbit is controlled primarily by the atomic charge and the velocity is :
v= e^2zc/nh =(7.2E-3c/n)= (alpha/n)c = 2.16E^6/n m/s.
The orbit radius is roughly 7.5 nm n^2 where n is the orbit level for hydrogen.

Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
Can hydrogen fill it's outside shells with two electrons?
No. Hydrogen is extremely unreactive because it only has one valence electron.
How many electrons does astatine need to fill it's outer energy level?
Electron shells of astatine: 2, 8, 18, 32, 18, 7 (electrons/shell)
In order to fill their outer most shells and become more stable atoms form what?
In order to fill their outer most shells and become more stable atoms form BONDS.
How many electron shells does calcium fill?
You can calculate the total capacity of an electron shell using the formula 2n2,... electron shell, it would need 10 electrons: 2 to fill the 1st shell and 8 to fill the2nd. ... In other words, in an atom with 20 electrons (which is the element calcium
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
Does the electrons go on the shells?
Yes electrons go on shells , that's the way the are organize . The more shells they fill the greater their atomic number .
How many electrons are in the outer shell of an atom with the atomic number 30?
one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1 one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1
In what orders do electrons fill orbitals?
Electrons fill orbitals in order of increasing orbital energy. The exact order of these energy levels is shown at the related link below.
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
How many electron fill an orbital?
Eight. The electrons with the highest energy levels are counted as the valence, or outer, orbitals. There are shells that contain more electrons such as D or F shells that can accommodate for 10 and 14 electrons respectively, however they are a lower energy level than their respective S and P shells that fill up before them which hold 2 and 6 electrons equaling a max of 8 outer orbitals.
How do molecular substances fill their outer shell?
Molecular substances can only fill outer shells if there are enough electrons present for this phemena to occur. Electrons can also be taken from other molecular substances in a process known as a Reduction Reaction.
Can hydrogen fill it's outside shells with two electrons?
No. Hydrogen is extremely unreactive because it only has one valence electron.

Why nonmetals do not have free electrons which conduct electrical energy?
Because the outer shells are very close to the nucleus and the number of electrons in the outer shells are between 4-8. Therefore, they are not freed from the nucleus easily rather they look for some more electrons to fill its outer shell which is technically called as covalent bond.
