Answer: 1+
Justification:
The ionization energies tell the amount of energy needed to release an electron and form a ion. The first ionization energy if to loose one electron and form the ion with oxidation state 1+, the second ionization energy is the energy to loose a second electron and form the ion with oxidation state 2+, the third ionization energy is the energy to loose a third electron and form the ion with oxidation state 3+.
The low first ionization energy of element 2 shows it will lose an electron relatively easily to form the ion with oxidations state 1+.
The relatively high second ionization energy (and third too) shows that it is very difficult for this atom to loose a second electron, so it will not form an ions with oxidation state 2+. Furthermore, given the relatively high second and third ionization energies, you should think that the oxidation states 2+ and 3+ for element 2 never occurs.
Therefore, the expected oxidation state for the most common ion of element 2 is 1+.
When an object enters the Earth's atmosphere, it experiences a few forces, including gravity and drag. Gravity will naturally pull an object back to earth.

A. the density stays the same unless given an external catalyst
The conductance of the electric current through the electrolytic solution increases with increase in concentration.
<h3>
What is electrolytic solution?</h3>
Electrolytic solutions are solutions that are capable of conducting an electric current due to presence of ions.
The current flowing in an Electrolytic solutions is calculated as;
Q = It
I = Q/t
where;
Increase in the concentration of the charges, increases the amount of charges in the solution and hence the conductance of the solutions will increase as well.
