The electrons "orbit" the nucleus of an atom. They do so because they are attracted to the positive charge of the protons inside the nucleus. They do not usually leave the atom because of this attraction, and do not usually fall into the nucleus because they are moving.
There are 3 electron shells in Aluminum. The first shell holds 2, the second shell holds 8, and the third shell holds 3. This equals 13, its Atomic Number. http://www.chem4kids.com/files/elements/013_shells.html

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.
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.
the first shell holds 2 and the second one holds 8 so you would need 2 shells!
iron has 4 shells because there are 30 electrons.
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.

Electrons are found in the shells and clouds.
Magnesium has 3 outer electron shells. It has 12 electrons with 2 in the first shell, 8 in the second shell, and 2 in the third shell.
s holds 2 electrons (e-)p holds 6 electrons (e-)d holds 10 electrons (e-)f holds 14 electrons (e-)This is true if you mean orbitals and not orbits.
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
