Explanation:
An atom is made up of:
- Protons which are the positively charged particles
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
To find the nuclear charge:
We use the effective nuclear charge formula:
Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)
The shielding electrons are the non-valence electrons in the inner orbitals.
For example:
Ne:
atomic number = 10
Effective nuclear charge = 10 - (2) = 8+
Number of non-valence electrons is 2
The effective nuclear charge is 8+
Overall charge:
Charge = number of protons - number of electrons
For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

I believe the correct answer from the choices listed above is the third option. It would be chromium (Cr) that is a transition metal. The 38 elements in groups 3 through 12 of the periodic table are called "transition metals<span>". Hope this answers the question. Have a nice day.</span>
Biochemical sediment like black shale (carbonaceous shale) and lignite and coal will form from the weathering ie reduction and decomposition of plant organic matter and thus store it in the geosphere, Also, carbon is naturally sequestered in the formation of carbonate rocks like limestone by combination of the carbon dioxide in the oceans (which may be in the form of carbonic acid) with metals to form calcium and magnesium carbonate compounds.
