Samarium has six electron shells.
Six.
The atoms of the element samarium (atomic number 62) have the electron configuration [Xe] 4f6 6s2
They have the same number of shells (or energy levels).
The correct number of electron clouds or shells sodium has is 3.
The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
Livermorium has 7 electron shells.
Neptunium has seven electron shells.
Neptunium has 7 electron shells.
It is to do with the number of electron shells it has. it has the least number of shells in group 7, it is is easier to gain an electron as the attraction is strongest from the nucleus of the element.
Electron shells
Beryllium has two electron shells.
4 electron shells; 2 electrons in first, 8 in second, 8 in third and 2 in valence shell.
They have the same number of electron shells.
