Each atom on the Periodic Table has a different number of electrons which corresponds to its element number. The electrons are located in different atomic orbitals, or electron clouds, labeled s, p, d, and f. The numbers of electrons within each orbital is determined by quantum mechanical rules, but can easily be looked up in a table of electron configurations.
The number of electrons in a neutral atom is equal to the atomic number. In Mercury's case that number is 80.
2n2 where n is the principal quantum number.
n=1, total 2 (1s2)
n=2 total 8 2s2, 2p6
n=3; total 18 3s2, 3p6, 3d10
It depends on which element the atom is. In a neutral atom, the number of electrons is the same as the number of protons, which is the same as the atomic number.
It depends on which element it is .
there are 8 electrons in the 3rd layer.

Your question is a bit vague, but if you are enquiring about the first electron shell in an atom, it holds a maximum of two electrons.
how many particles are in a electron cloud? Theres the neutron, proton, and electron...just like any regular atom and to answer ther second question, it depends on what atom your talking about. For example, a Hydrogen Atom has two electron, but there rotating is so fast that its hard to pin-point where exactly it is. Try to imagine it as a fan, the wings are the electrons but when it rotates it looks like one single mass... hopefully that helps
How am i supposed 2 no? im the 1 who asked the question!

There can only be 2 electrons in each single orbital, and they will be on opposite sides of the electron cloud (orbital).
In a neutral atom, the charge on the electron cloud is balanced by the carge on the atom's nucleus. The nucleus has a positive charge proportional to the number of protons in it. This attracts and holds the negatively charged electrons in the electron cloud. And in a neutral atom (not an ion), there will be as many electrons in the electron cloud as protons in the nucleus. The charges will balance.

None, electrons are in the electron cloud, not the nucleus
The first ring of the electron cloud holds two electrons. All rings following it hold eight.
It is impossible to know exactly where an electron is. Thus, the size of an electron cloud can be given only in terms of probability. Even then, the size of the electron cloud depends on how many electrons an atom possesses.
Fluorine's atomic number is 9. Thus, fluorine has 9 protons and 9 electrons. As with every atom, all 9 of fluorine's electrons are found in the electron cloud.
