The electron configuration of the ion Cr(III)+ is 1s22s22p63s23p63d3
No, it is not a gas, it is an element.
No. it is a transition metal
Chromium (Cr) is a monoatomic metal.
[Ar]3d54s1
[Ar]3d54s1
Chromium is one of the "odd" elements when is comes to Noble gas configuration. Instead of being [Ar] 4s23d4, like many of us looking at a periodic table would think, which is WRONG, the actual configuration is: (ANSWER:) [Ar] 4s13d5
No, it is a noble gas
Radon is a noble gas and is radioactive.
[Ar]3d54s1
[Ar]3d54s1
[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.
Ar is the symbol for the noble gas - argon.
