7. It is in period 7, at the bottom of the Periodic Table.
46
A neutral xenon atom has 54 electrons. Two of its electron shells would be completely filled, with 2 and 8 electrons, leaving 44 electrons in the remaining electron shells.
Calcium has 20 electrons in its electronic configuration, therefore it has 20 shells.
Beryllium has one outer electron shell with two electrons.
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.
Livermorium has 7 electron shells.
Livermorium has 7 electron shells.
Livermorium has 116 protons.
iron has 4 shells because there are 30 electrons.
46
Tungsten has 74 electrons!!
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.
Mercury has 80 electrons which means there are 6 shells in a neutral atom of mercury.
Berkelium has 97 electrons, which means it has 7 electron shells.
1
A neutral xenon atom has 54 electrons. Two of its electron shells would be completely filled, with 2 and 8 electrons, leaving 44 electrons in the remaining electron shells.
Uranium has 92 electrons, which means it has 7 electron shells.
