What is common to every element in a period?
The energy sublevel (s, p, d ,f) is always the same.
What Period 4 element is in the same group as F?
Br (Bromine) is a period 4 element in the same group as F.
Why is the period of an element determined by an electron configuration?
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
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.

chlorine (Cl)
What is the liquid in the period as Fe?
It's BROMINE. That is the element that is a liquid in the same period as Fe.
Does every atom of the same element have the same same atomic number?
yes
Does atom of the same element have the same number of proton?
Yes that is true Every atom of a given element does have the same number of protons.
What do you notice about the number of energy levels in an atom of an element in the period the element is in?
The atom of an element in the third period of the Periodic Table has 3 energy levels and so on. Also, atoms of elements in the same group have the same no. of valence electrons.
Name the element in the same group as lithium and the same period of iron?
Potassium (K)
