your answer is A if i am wrong let me know
A - its condensation and gas particles have a higher kinetic energy
Alkaline Earth Metals are the elements located in the second period from the left of the periodic table. These elements lose two electrons to form the stable octet when forming an ionic bond, resulting in a net charge of +2. Because they’re trying to get rid of those electrons to get to the stable octet, it’s easy to remove them - this means that the ionization energy of these elements is relatively low. Finally, since they’re looking to get rid of electrons, they certainly aren’t trying to gain any, meaning that their electronegativity is relatively low.
The correct answers are A and D.
The answer is c because thats the number when combined with a metal. +1 is when its combined with a nonmetal.
I guess it is the second one but you missed the state symbols.
