D) The elements are found in the same column on the periodic table.

Answer 1

I would have to go with.
D) The elements are found in the same column on the periodic table.

@abdullahSadiqi being in the same period (same row of the periodic table) does not mean similar chemistry in the way being in the same group (same column) does. Bonding behavior is largely determined by valence electron count and configuration which goes along with period.

alkali metals all bond in same proportions with halogens, for example. potassium chloride and sodium chloride are 1:1 combinations because both potassium and sodium eagerly give away their single valence electron (giving them a full outer shell) to chlorine, which violently rips away electrons from most other elements so that it can complete its full outer shell.
