The electron configuration for this atom is 1s22s22p63s23p64s23d64s2. There are 6 d electrons.
A neutral iron atom has 26 electrons. All iron atoms have 26 protons in their nuclei, which is why their atomic atomic number is 26. Protons have a positive charge, while electrons have a negative charge, so a neutral iron atom has 26 protons and 26 electrons.
Mercury (the neutral atom) has 8o electrons.
3d^6 Six electrons in the outer shell.
The electrons (especially the valence electrons)
The maximum number of electrons that can enter each type of sublevel in an atom are as follows: s sublevel: 2 electrons p sublevel: 6 electrons d sublevel: 10 electrons f sublevel: 14 electrons

That would be 0. The ground state of every element except for Hydrogen is 1s2 which has no unpaired electrons. (only valence electrons have the ability to be unpaired). Full configuation of Fe would be: 1s2 2s2 2p6 3s2 3p6 4s2 3d6 WWWWWWWWWRRRRRRROOOOOOONNNNNNGGGGGGG!!!!!!!
An atom of yttrium (Y) has an electron configuration of 1s2,2s2,2p6,3s2,3p6,4s2,3d1, so it has one unpaired electron in the 'd' orbital.
Chromium is in the d block. It contains 24 protons.
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
around or outside the nucleus :D
Mercury (the neutral atom) has 8o electrons.
3d^6 Six electrons in the outer shell.
5 unpaired electrons There are 5 unpaired electrons in the Fe3+ ion. The reason for this is that Iron has the electron configuration Ar3d5.
