1.As with any grid, the periodic table has (left to right) and (up and down). 2.Every row is called a .
3.All the elements in the same period have the same number of .
Each column is called a .
4.The elements in each group have the number of electrons in the outer orbital (or valence electrons).
5.Noble gases and helium are considered “happy” because their shell is .
