For example,11. Na is arranging the electron is 2, 8, 1. The valence electrons = 1 is among the 1. There are a number of energy levels, three levels of power. Is the energy level n = 1, n = 2, n = 3 in the third period.There are 36 Kr electron 2, 8, 18, 8. The valence electrons = 8 8 is in the village. There are a number of energy levels, 4 levels of energy. Is the energy level n = 1, n = 2, n = 3, n = 4 in period 4.14. Si has 4 electrons are 2, 8, The valence electrons = 4 and therefore are among the 4. There are a number of energy levels, three levels of power. Is the energy level n = 1, n = 2, n = 3, in the third period. The table element that is very common today. In the format as shown in Figure 1, where the vertical element is divided into 6 rows, called the village. The elements in a vertical split into small groups with A group B with 8 A Moo Moo IA to VIIIA:Famous Moo Moo 1 alkali metals Li Lithium lithium Na Sodium sodium (Natrium) K Potassium (Kalium) Pro thaet Siem Rubidium Rb rubidiam Cesium Cs caesium Francium francium Fr
