If an element is the last element in its period what does this mean?
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
What Period 4 element is in the same group as F?
Br (Bromine) is a period 4 element in the same group as F.
What element is a metal of group 4 with 28 protons?
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.

What element is Group 1 period 4?
element K, or potassium
The element argon is the last element in its period What does this tell you about?
Since argon is the last element in its period, it is a noble gas. This means that it has a full outer shell of electrons (specifically a full p orbital), and is not very reactive (at all).
What is the element in group period 4?
calcium
