CArbon has an atomic number of 6. There are therefore only 2 electrons in C4+

Cr and Fe have four unpaired electrons in their 2 plus ions.
b. Fe3 plus ions
there are 10 electrons.
29 protons and 27 electrons.

In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
There are 4 unpaired electrons in the ground state electron configuration of an Fe atom. These 4 unpaired electrons are in the 3d subshell.
Cr and Fe have four unpaired electrons in their 2 plus ions.
There is merely one unpaired electron in Potassium. The electron configuration of potassium is [Ar]4s^1. This means that potassium has all the electrons of argon, plus one more in the 4s orbital. All the electrons of argon are paired, so the one electron in the 4s orbital is the only unpaired electron.
N2+ and N2- I just did it on mastering chem and it worked I'm pretty sure its because when you count the valence electrons in N2+ and N2- you get 9 and 11 respectively because these are odd there has to be an unpaired electron in each
b. Fe3 plus ions
phosphorus (P) as it has three unpaired electrons.
78 electrons
there are 10 electrons.
567
29 protons and 27 electrons.
