And in the first energy level, which if used V. E. are supposed to provide hydrogen in A village 1. Lessons 1, however, may be considered to belong to the same village A 7 because 7 A village. The lack of an electron is only 1 selection.
And in the first energy level, which is used as a basis VE should be arranged hydrogen 1 among Class 1A, although it may be considered to be in the same category 7A 7A lacks only 1 electron.
And in the first energy level, which, if used V.E. As criteria should arrange hydrogen are among the 1A periods 1, however, may be considered among the 7A too. Because of the lack of 7A electron only 1.
