WebDec 8, 2024 · The number of elements in a period is determined by the maximum number of electrons that may be accommodated in an atom’s various shells. Groups – Groups are the vertical columns in a periodic table. In the long form of the periodic table, there are 18 groups. The elements in a group do not have the same atomic number. WebApr 28, 2024 · Oxygen is found in Period 2, Group 16. Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through 12.
