Based on the information in the table, which elements are most likely in the same periods of the periodic table?

Heyyy,
The vertical columns (groups) of the periodic table are arranged such that all its elements have the same number of valence electrons. All elements within a certain group thus share similar properties.
Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Elements are arranged in the increasing order of atomic numbers. Elements in the modern periodic table are arranged in 7 periods and 18 groups. Horizontal rows are called periods and vertical columns are called groups. Elements are placed in periods based on the number of shells in their atoms.
Hope this helps...
