Answer:
A. One unpaired electron
B. 5 unpaired electrons
Explanation:
In A ,Fe is in +3 oxidation state and Electronic configuration- [Ar]3d5
And NO2 is a strong field ligand hence it causes pairing in t2g orbitals and results one unpaired electron in dZX orbital.
In B, also Fe is in +3 oxidation state but F is weak field ligand hence causes no pairing of Electrons hence it results 5 unpaired electrons with electronic configuration t2g^3 eg^2
The last option: include all of the known electrons for the adam it represents
that statement is not true because Lewis dot structures only show valence electrons
Answer:
a chemical reaction
Explanation:
The fact that you are combining two different elements together makes this a chemical reaction. (hope that helps)
The electronegativity of an atom describes how much an atom attracts an electron, whether it be in a covalent bond or just on its own.
