Magnesium
Among the elements Barium has the lowest Ionization Energy.
<h3>What is Ionization Process ?</h3>
The process by which any neutral atom gets converted into electrically charged by gaining or losing electron is called Ionization Process.
K is an alkali metal it has to lose one electron to attain stable electronic configuration of an inert gas
For removing second electron , a stable configuration has to be broken and so will require high amount of energy.
Ca and Ba are alkaline earth metals.
They both have to lose 2 electrons to attain stable electronic configuration of noble gas.
They have low Iow Ionization Energy as compared to K.
Ca has higher Ionization Energy as compared to Ba because when we move down the periodic table , The ionization energy decreases.
Hence , Among the elements Barium has the lowest Ionization Energy.

In a chemical equation, the symbol that means “dissolved in water” is (aq).
2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!
Maybe because meiosis have more chromosomes than mitosis but don't put that on there but that maybe it it because in class we have not went over that yet
