Mendelevium has seven electron shells.
2, there is always 2 in the inner shell.
Carbon has two electrons in its inner shell and four in its outer shell.
there are 2 electrons in the inner shell of a hydrogen atom.
Sulfur has six electrons in its third electron shell.
Valence electrons are located in the outermost shell in an atom. Chromium has only one valence electron.
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
1, because it has an atomic number of one, meaning it has 1 proton & 1 electron. It takes 2 electrons to fill the first electron shell, but hydrogen only has 1. So it remains at the 1st shell.
The valence shell of sodium has one electron.
An electrically neutral oxygen atom has eight electrons, one for each proton in its nucleus. Two electrons are in the inner shell and six are in the outer shell.
Mendelevium has 101 electrons.
Mendelevium has 101 electrons.
