The answer is B, density is d=m/v
Explanation:
A compound or molecule which will have least dissociation and that is not able to given hydrogen ion easily upon dissociation will also have a low value of 
.
Dissociation of the given compounds or species will be as follows.
As, chemical formula of bicarbonate is 
and due to the presence of a negative charge it is difficult to lose a positively charged hydrogen ion. This is because oppositely charged ions will be bonded by strong force of attraction.
Hence, it will not easily lose a hydrogen ion due to which bicarbonate has the lowest .
Thus, we can conclude that out of the given species bicarbonate has the lowest .
It allowed him to realize that the mass of an atom is concentrated at its center because the atoms mostly went through the foil but some were deflected. He also realized that an atom probably wasn't just empty space and scattered electron and it had a positive center.
The name given to an ion that has lost electrons is cation. Details about cations can be found below.
<h3>What is a cation?</h3>
A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.
Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.
A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.
Therefore, it can be said that the name given to an ion that has lost electrons is cation.

Answer:
Alkaline earth metals
Explanation:
Group 2 has 2 valence electrons that they lose when being ionized, thus making their charge 2+.
