Question

Which one of the folowing sets of quantum numbers represents an electron with the highest energy? Select one: n = 5, l = 0, ml = 0, ms = +1/2 n = 3, l = 2, ml = -2, ms = +1/2 n = 4, l = 2, ml = 1, ms = -1/2 n = 4, l = 0, ml = 0, ms = +1/2 n = 4, l = 1, ml = 0, ms = -1/2 Which of the following is the general electron configuration for the outermost electrons of the elements in Group 5A? Select one: ns^2 np^4 ns^2 np^3 ns^2 np^1 ns^2 np^6 ns^2 np^5 An element with the general electron configuration tor Its outermost electrons of ns2npl would be In when element group?

Answer 1

16.

Higher energy level always depends on the principal quantum number

It is denoted as

That means in the option A we have n=5 that means electrons with higher energy.

17. The number of electrons present at the valence shell of 5A group is 5

The general electronic configuration is

Hence option B is the correct answer.

18 . An element with the electronic configuration for its outer most electrons of will come in group 3A .
