The electron configuration of Thallium III ion (Tl3+) is [Xe] 4f14 5d10, where [Xe] represents the electron configuration of xenon (54 electrons) which precedes thallium on the periodic table. Thallium loses 3 electrons to achieve a noble gas configuration.
[Ar] 3d3Cr3+ has 18 core electrons, corresponding to the element Argon, and... 24 - 18 - 3 = 3 valence electrons.The noble gas electron configuration for chromium(III) ion is [Ar] 3d3.
+3
Neithr!!! An atom of Cobalt contains 27 electrons.
The electron configuration of nickel (III) ion is [Ar] 3d7. Nickel has an atomic number of 28, and by losing 3 electrons to become Ni3+, it adopts the electron configuration of argon (Ar) with 3d7 electrons remaining in the 3d orbital.

The ionic chemical formula for cobalt (III) chloride is CoCl3. In this compound, cobalt has a +3 charge, indicating it has lost 3 electrons, while chloride has a -1 charge, indicating it has gained 1 electron.
The formula for cobalt III nitride is CoN.
Yes, when cobalt(III) bromide reacts with potassium sulfide, it will form cobalt(III) sulfide as a solid precipitate, as cobalt(III) sulfide is insoluble in water.
The electron configuration of the ion Cr(III)+ is 1s22s22p63s23p63d3
The formula for cobalt (III) carbonate is Co2(CO3)3.
CoCl3
The formula for cobalt(III) chromate is Co2(CrO4)3.
