The answer is (E). protons.
The atomic number of an atom is equal to the number of protons in the nucleus.
I hope this helped.

<h3>Monoatomic vs Polyatomic Ions</h3>
In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include
,
, and ![Fe^{3+](https://tex.z-dn.net/?f=Fe%5E%7B3%2B)
Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.
Examples of polyatomic ions are

,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)
Thus, from the diagram:

<span>When sugar or nacl is dissolved in water, the resulting solution is classified as homogeneous mixture.In the name homogeneous itself it refers to the meaning same,so it is referred as same proportions.For example, soda pops and lemonade, they can really be as solids, fluids, and gasses. Homogeneous mixture can likewise be a mix of these structures, as in a fluid gas mixture.</span>
Answer:
50.5 g/dL
Explanation:
From the question given above, the following data were obtained:
Mass of Al₂(SO₄)₃ = 101 g
Volume (V) = 200 mL
Concentration of solution (g/dL) =?
Next, we shall convert 200 mL to decilitre (dL).
This is illustrated below:
1 mL = 0.01 dL
Therefore,
200 mL = 200 mL / 1 mL × 0.01 dL
200 mL = 2 dL
Therefore, 200 mL is equivalent to 2 dL.
Finally, we shall determine the concentration of the solution in g/dL as follow:
Mass of Al₂(SO₄)₃ = 101 g
Volume (V) = 2 dL
Concentration of solution (g/dL) =?
Concentration of solution (g/dL) = mass /volume
Concentration of solution (g/dL) = 101/2
= 50.5 g/dL
Therefore, the concentration of the Al₂(SO₄)₃ solution is 50.5 g/dL
It would be an electronic charge of +2 because there are 4 protons and 2 electrons
