each belongs to a different nervous system

one controls voluntary activity, one controls involuntary activity

one controls thinking, the other controls feeling

Elements in the same group in the Periodic Table of the Elements have the same:

51% Answer Correctly

number of atomic mass units

number of electrons

number of electrons in their outer electron shell

number of electron shells
Solution

The columns of the Periodic Table are called groups and all elements in a group have the same number of electrons in their outer electron shell. The group that an element occupies generally determines its chemical properties as the number of outer shell electrons establishes the way it reacts with other elements to form molecules. So, because each element has the same number of electrons in its outer shell, each has similar reactivity.
