What is element Ar 3d104s24p5?
Br
What is the noble-gas notation of Br?
The electron configuration of bromine is: [Ar]4s23d104p5.
What is the chemical formula Cr plus 2 and Br-1?
Cr3br
What is the gas noble notation for Br?
[Ar] 4s2 3d10 4p5
What is the noble gas configuration of Cr?
[Ar] 3d5 4s1
What is the noble-gas notation for Br?
[Ar] 4s2 3d10 4p5
What is the oxidation number of chromium for CrBr2?
Br is -1 (MINUS 1) so Cr is +2
Is the isotope 79-Br or 81-Br more common and why?
79-Br is more common because its abudance is 50.69%. 81-Br's abudance is 49.31% making it less common. Abudance is the rate at which the isotope is found in nature. In this case out of every 100 Bromine atoms you found 51 would be 79-Br and 41 would be 81-Br.
What is Ar 5s2 4d10 5p5?
what is 5s2 4d10 5p5
What is the electron configuration of Br using the noble gas shortcut?
35Br = [Ar core],4s2,3d10,4p5
What is the electron configuration using noble gas notation for chromium III ion?
[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.
If atom is chemically stable if it and outer energy level is filled with what?
A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following: Sc = [Ar]4s23d1 Ti = [Ar]4s23d2 V = [Ar]4s23d3 Cr should in theory be Cr = [Ar]4s23d4 but it is not. Half filled shells are more stable so the configuration is Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is Mn = [Ar]4s23d5 one full and one half filled level.
