What is one similarity and one difference between elements of group 2 and group 7?
Wyatt AtkinsSee below.
Similarity: For both, the atomic radius increases down the group.
The difference is that group 7 has melting and boiling points that rise as you move down the group, whereas group 2's melting point decreases as you move down the group.

Group 2 elements (alkaline earth metals) and Group 7 elements (halogens) are similar in that they are highly reactive; however, Group 2 elements usually form cations by losing two electrons, whereas Group 7 elements form anions by gaining one electron.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
