Determine the oxidation state of cr in cr(so4)2.
2 answers:
<u>Answer:</u> The oxidation state of chromium in the given compound is +4
<u>Explanation:</u>
Oxidation state is the number that is assigned to the element when it gains or looses electrons.
If an element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.
We take the oxidation state of chromium atom be 'x'.
Oxidation state of sulfate ion = -2
Evaluating the oxidation state of chromium atom:
Hence, the oxidation state of chromium in the given compound is +4

Explanation:
As we know that sum of only total number of protons are also known as atomic number of an atom. And, the sum of total number of protons and neutrons is known as atomic mass of an atom.
Number of protons help in determining the identity of an atom whereas the number of neutrons can be same for two or more number of atoms. But the number of protons will remain the same for a particular atom and for its isotopes.
For example, tex]^{1}_{1}H[/tex] and are isotopes and each of them contains 1 proton.
thus, we can conclude that the number of protons in their nuclei would allow you to determine whether two atoms are of the same or different elements.
