Extended information:

1. The period number of an element is equal to the number of electron shells outside the nucleus;

2. Main group elements The sequence number is equal to the number of electrons in the outermost shell;

3. To determine the group number, you should first determine whether it is the main group or the subgroup. The method is to use the atomic number to gradually subtract the number of elements in each period, which can be obtained by the final to determine the difference. In the first to fifth cycles, when the final difference is less than or equal to 10, the difference is the family ordinal number. When the difference is 8, 9, or 10, it is family VIII. When the difference is greater than 10, 10 is subtracted, and the final result is the family ordinal number. .

In the sixth and seventh cycles, the difference is 1: Group IA, the difference is 2: Group IIA, the difference is 3~17: Lanthanide or Actinium series, the difference is between 18 and 21 Between: minus 14, the difference is 22~24: Group VIII, the difference is greater than 25: minus 24, it is the corresponding main family.
