∙ 14y agoA correct generalization about this is that every member of group 18 has a full outer energy level. For helium, the specific number is 2 and for all the others it is 8.

Period in chemistry?
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
What is the largest number of electrons that can be in the outermost level in elements in row 1 in the periodic table?
8
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
What the maximum number of electron can go in the first three energy levels subatomic particles?
the first energy levels hold 2, 8, and 18 a total of 28 electrons
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
Can some elements have the same number of electrons in their outermost level?
Elements in the same group have the same number of valence electrons.
How does the number of outer energy level electrons related to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..
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..
What are the parts of Elements?
At the first level, protons, neutrons, and electrons.

If the first energy level is complete with two electrons then what has two elements?
the atom
Do a family of elements share the same number of valence electrons?
Yes they do. Groups/Families tell the number of valence electrons (the number of electrons in the outermost energy level).
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.
What number of electrons in the outermost energy level determines how an atom will?
All the electrons in the outermost shell are relevant for chemical reactions. For many elements, the number of such electrons is between 1 and 8, but for some of the higher-numbered elements, this number can be greater than 8.
What is the largest number of electrons that can be in the outermost level in elements in row 1 in the periodic table?
8
