A free electron is able to move as it is in the outer shell of the atom. So free electrons can carry a charge. If an atom has free electrons it is able to conduct electricity.
Inner shell electrons cannot carry a charge as they are closer to the nucleus.
there are 2 electrons in the inner shell of a hydrogen atom.
Mendelevium has seven electron shells.
Sodium has two inner shells. The first inner shell can hold up to 2 electrons, while the second inner shell can hold up to 8 electrons. Sodium's electron configuration is 2-8-1, with one electron in the outermost shell.
speed of electrons varies from shell to shell . it increases from inner orbit to outer orbit
An electron in an atom's outer shell is shielded from the nucleus by inner-shell electrons. These inner-shell electrons repel the outer electron, reducing the net attractive force from the nucleus. This shielding effect helps explain why outer-shell electrons are more loosely bound and easier to remove during chemical reactions.
No, on the most inner shell, only 2 electrons can be held, but then on every other shell it is usally 8
on the innermost shell of any element there is 2 electrons (except for Hydrogen, but that's a different story) so the answer would be 2
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
These are the electrons that are not the valence electrons and are also known as core electrons.See the Related Questions and Web Links to the left for more information about valence and core electrons.
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
Oxygen has 8 electrons (2 in the inner shell, 6 in the outer).
Each electron shell corresponds to a different principle energy level. Each shell can contain only a fixed number of electrons.
