group 17
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.
All alkaline earth metals have two valence electrons.
All noble gases have the electron configuration s2p6.
For example the column 17 - halogens.
The Roman numeral at the top of a column on the periodic table indicates the number of valence electrons an element in that column has. Valence electrons are the electrons in the outermost shell of an atom and are involved in chemical bonding. Group IA elements have 1 valence electron, Group IIA elements have 2 valence electrons, and so on.
The answer will depend on what p5 is!
p5 cannot be simplified.

number of outermost electrons
If you were to see a P5 that would mean the batter popped out to the third baseman.
The number of electrons in the outer shell.
Atoms in column 7 of the Periodic Table have 7 electrons in their outer shell. Atoms are most stable when they have 8 electrons in their outer shell. So atoms of elements in column 7 have a strong attraction for 1 electron. Flourine being the smallest atom in that column has the strongest attraction for 1 electron.
Iron is in period 4 and column 8 of the periodic table because it has 8 total electrons in its outermost energy level, considering both valence and core electrons. The 3 valence electrons are in the 4s and 3d orbitals, which leads to its position in column 8.
