Answer:
False
Step-by-step explanation:
Elements in the same group in the Periodic Table do not have the same number of neutrons. They have the same number of electrons in the valence shell. This explains partially its chemical reactivity. For instance, halogens (elements in the Group 17) have 7 valence electrons so they tend to gain 1 electron to complete the octet in the valence shell.
The statement "Because atoms of elements in the same group of the periodic table have the same number of neutrons, they have similar properties." is False
