Which of the elements which have their valence electrons in the second energy level is the largest?
Neon
Elements in a group or family have similar properties?
Because groups/families determine how many valence electrons the element will have. Therefore, all the elements in a group/family have the same number of valence electrons Chemimal and Physical.
If the first energy level is complete with two electrons then what has two elements?
the atom
Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
Which elements fits the following description 2 electrons in the n3 energy level?

How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
Do group 7 electrons have 7 electrons in the outer shell?
Group seven elements have 7 electrons in their outermost energy level.
How many electrons does an atom need to a outer energy level?
There are different numbers of valence electrons in different elements.
How does the number of the outer energy level electrons relate to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..
