Random
Orbital
Unknown
Electrons are thought to be found randomly within cloud-like orbitals around each atoms' nucleus, but it is physically impossible to ever know the precise location of an electron, for even if you were to look at them through a high-powered microscope, that small portion of light would be enough energy to change their location and path of movement.
Two of the terms are speed and direction.
With coordinates. A reference frame is chosen (a point of origin, and directions), and the position is described with two or three numbers (one for each dimension required), in relation to the point of origin.
there are a maximum of 18 electrons on the level 3 or the third shell
When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.
6Li has 3 protons, neutrons and electrons. 7Li has 3 protons, 4 neutrons and 3 electrons.
I think you are referring to the 3 quantum numbers, n, l m; principal azimuthal and magnetic. Together with the spin quantum number they "define" an electron- but I would hesitate to call this the electrons location- Heisenbergs uncertainty principle gets in the way of a simultaneous knowledge of energy and location.

Degenerate, decadent, and backwards.
Nitrogen typically forms chemical bonds in which it either gains or shares 3 electrons. So 3 is the number, or more precisely -3, since gaining electrons gives a negative charge.
