Question

which property do the elements in each column of the representative elements series of the periodic table have in common? (1 point)
number of neutrons
number of protons
number of orbitals
number of valence electrons

Explanation:

Elements in the same column (group) of the periodic table are in the same group. The defining characteristic of elements in a group is that they have the same number of valence - electrons, which determines their chemical reactivity and bonding behavior. The number of neutrons varies among isotopes, the number of protons defines the element itself and is unique for each element, and the number of orbitals is related to the energy levels and electron - configurations in a more complex way than being a common property within a group.

Answer:

number of valence electrons
