it has your face
Not really, I learned about this recently and I am positive that groups are vertical and periods are horizontal. One example would be the noble gases group, it is located in the 18th vertical column from the left
The full electron configuration in question is 1s2 2s2 2p6 3s2 3p1. Adding up those electrons gives us a total of 13. Referencing a periodic table, we see that the atom with 13 electrons, and thus 13 protons to keep it neutral, is aluminum.
the period
The horizontal rows on the periodic table are called periods.
a horizontal row is called a period.a vertical row is called a group
Bromine belongs to 4th horizontal row. Its symbol is Br. It has 7 valence electrons.
No, the number of valence electrons does not stay the same throughout the horizontal rows on the periodic table. The number of valence electrons stays the same throughout the vertical columns of the periodic table.
It depends in the first row its 2, the second 8, the third 16 and that's all i remember
The third horizontal row is named the Third Period or Period 3. The elements are, from left to right, Sodium(Na), Magnesium(Mg), Aluminium(Al), Silicon (Si), Phosphorus (P), Sulphur(S), Chlorine*Cl), and Argon(Ar).

Saints Row The Third takes up 10 gigs.
All of the elements in a given horizontal row (or period) have the energy level, but they differ in the number of valence electrons.
