What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.

Is there a relationship between the group number of each element and the number of electrons in the outermost energy level?
Yes: group number 1 has 1 valence (outer-shell) electron, group 2 has 2 valence electrons ect, until the noble gases, in group 8, which have 8 valence electrons. This does not include the metals in the middle! H is the first group 1, Be is the first group 2 B is the first group 3, C is the first group 4, N is the first group 5, O is the first group 6, F is the first group 7 and Ne is the first group 8. He is the odd one out: because whilst it is in the eighth group, as it has a full outer shell, it only has two electrons. That is because the first shell only requires two electrons to fill it.
