A maybe I said maybe hope help
Explanation:
..
Answer: 1+
Justification:
The ionization energy is the amount of energy needed to loose electrons and becomes ions.
The first ionization energy is the energy needed to liberate one one electron and form the ion with oxidation state 1+.
The second ionization energy is the energy to release a second electron and form the ion with oxidation state 2+.
The third ionization energy is the energy to leave a third electron free and form the ion with oxidation state 3+.
The relatively low first ionization energy of element 2, shows it it will lose an electron easily to form the ion with oxidations state 1+.
The second and third ionization energies are very high meaning that the ions with oxidation staes 2+ and 3+ will not be formed.
Therefore, the answer is that the expected oxidation state for the most common ion of element 2 is 1+.
Many of the atomic masses listed on the periodic table are decimal values because it's the weighted average mass of all of the isotopes of that element.
In this theory, gas molecules are deemed to be at constant random motion and have perfectly elastic collisions with each other. They bounce of each other. These particles are assumed to have a spherical shape. Also, there are no attractions between the molecules.<span />
