Electrons are found in shells around the central part of an atom. These shells represent different energy levels in which electrons can be located. The arrangement and movement of electrons in these shells determine the chemical properties of the atom.
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
The particles found in the area surrounding the nucleus are called electrons. Electrons are attracted to the protons in the nucleus, but are repelled from other electrons. This is why they can be found orbiting the nucleus.
Sodium has 3 electron shells. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. Sodium has 11 electrons in total.
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.
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
Electrons are confined to specific energy levels or shells around the nucleus of an atom due to quantum mechanics. Each electron shell corresponds to a specific energy level, and electrons can move between these shells by absorbing or releasing energy. So, we can say they are "localized" in their respective shells rather than "trapped."
Electronic configuration is the arrangement of electrons in the respective shells of an atom when it is in its ground state,(where all of its electrons are in their respective lowest energy orbitals). This is shown as the number of electrons in the subshells s, p d, f, g. The subshells are in energy sequence, low to high. An example :- Osmium full electronic configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 4f14 5d6 6s2 The filling of energy levels generally follows the aufbau principle.

iron has 4 shells because there are 30 electrons.

Electrons are found in the shells and clouds.
Yes electrons go on shells , that's the way the are organize . The more shells they fill the greater their atomic number .
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
yes they do :D
