Which is a way that the elements are grouped on the periodic table? (2 points)
elements in the same row have the same number of protons.
elements with similar bonding properties are in the same column.
elements in the same column have the same number of neutrons.
elements with similar mass are placed in the same column.

I think the correct answer from the choices listed above is the second option. A way that the elements are grouped on the periodic table would be that elements with similar bonding properties are in the same column. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital.

Wish i can but don’t know this
