Give the oxidation state of the metal, number of d electrons, and the number of unpaired electrons predicted for [co(nh3)6]cl3.

Oxidation state: +3

No of d electrons: 6

Unpaired electrons : 4

Explanation:

Oxidation state: X+6(0)=+3

X=+3

And Co has Atomic number 27

And here it is Co+3 hence [Ar]3d6

Since H2O is weak field ligand no pairing of Electrons involved. Hence there are 4 unpaired electrons. 2 in t2g and 2 in eg orbitals.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

explanation:

0.07 g/cm³

1.37 g/cm³
