Answer:
Explanation:
In a chemical formula, the oxidation state of transition metals can be determined by establishing the relationships between the electrons gained and that which is lost by an atom.
We know that for compounds to be formed, atoms would either lose, gain or share electrons between one another.
The oxidation state is usually expressed using the oxidation number and it is a formal charge assigned to an atom which is present in a molecule or ion.
To ascertain the oxidation state, we have to comply with some rules:
- The algebraic sum of all oxidation numbers of an atom in a neutral compound is zero.
- The algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to the charge on the ion.
For example, let us find the oxidation state of Cr in Cr₂O₇²⁻
This would be: 2x + 7(-2) = -2
x = +6
We see that the oxidation number of Cr, a transition metal in the given ion is +6.
Answer:
The modification that yields the first amino acid depicted is lysine
Explanation:
Lysine being an amino acid used in preparation of various medicine. It is used to prevent cold as well as sore throat, which is found to be caused by the herpes simplex labialis. It can be used orally or can be directly applied over the skin. various foods have lysine in it and they are meat, cheese, certain fishes, eggs, soybeans, spirulina and also fenugreek seed. They are the building block for the protein particles.
It would be one electron in the outermost shell. Hope this helps!
Answer:
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.
