Question

Scientists believe that interactions between atoms depend mostly on the arrangement of the outermost electrons in each atom. This theory is MOST supported by the observation of similar reactions among elements —

with a similar atomic mass
with a similar atomic number
in a group (column) of the periodic table
in a period (row) of the periodic table

Answer 1

I’m pretty sure it’s in a group (column) of the period table. Hope this helps :)))

Answer 2

The atom of the element comprises electrons in shells. The interaction of atoms depends on the arrangement of the outermost electron is supported by the group of the periodic table. Thus, option c is correct.

What is a group in a periodic table?

A periodic table is the representation of the elements with symbols, atomic numbers, and atomic masses. They are arranged on a table in vertical columns and horizontal rows.

The vertical columns are called groups or families that are read from top to bottom of the table. The groups consist of elements that have identical valence electrons in their outermost shells.

This arrangement of the electron allows the bond formation between two or more atoms in a molecule. This allows the element to have similar physical and chemical properties.

Therefore, option c. the interaction of the electrons is supported by the group (column) of the periodic table.
