The electron configuration is [Ar]3d2.4s2.
[Ar]4s2
Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.
It has the same electron configuration as in a neon atom.
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
Electron Arrangement for Nickel: 1s22s22p63s23p63d84s2 the electron orbital arrangement in terms of increasing energy however is 1s22s22p63s23p64s23d8. Using the "noble gas core" method the arrangement can also be written [Ar]3d84s2. The arrangement for Ni2+: 1s22s22p63s23p63d8
The "charge" or oxidation number of oxygen (O) in an oxide such as TiO2 is always 2-. This means that the total charge on O in TiO2 is 2 x -2 = -4. Thus, the "charge" or oxidation number of Ti is 4+.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.
2
It has the same electron configuration as in a neon atom.
2
Helium has 2 electrons. hydrogen has one electron. Hydride ion is formed when hydrogen gains one electron, and thus hydride ion will also have 2 electrons.
The charge is 2+.
Chlorine
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
oxygens electron arrangement is 2 electrons then 6 electrons and that's all hope whatever your doing goes well!>0
2-
It has 2 electrons in the first shell, and 8 in the second as it gains an electron to form an ion so the configuration is 2,8.
