There are 80 electrons shells for mercury.
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
atoms try to get 10 electrons on shells around the atom. how many shells the atom has is based on the atomic number and atomic mass the atomic number determines how many shells their are.
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.
Hydrogen has only one valence electrons.
the answer is 4
iron has 4 shells because there are 30 electrons.
Tungsten has 74 electrons!!

There are 26 d-electrons in shells 4-6.
