Periods meaning in chemistry
WebThis arrangement is called the periodic table. The columns of the periodic table are called groups. Members of the same group in the table have the same number of electrons in the outermost shells of their atoms and form bonds of the same type. The horizontal rows are called periods. Periods correspond to the relationship of orbitals, or likely ... WebA period is a horizontal row of elements on the periodic table. For example, the elements sodium (\(\ce{Na}\)) and magnesium (\(\ce{Mg}\)) are both in period 3. The elements …
