It would be Violet because it has the shortest wave length, while red has the longest wave length so it comes out the least of the colors.
2 valence electrons
Explanation:
Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons.
No it is not
hope this helped
The answer is four hundred
