Answer:
These elements tend to gain or lose electrons easily (option C.) is not true in regard to noble gases.
Explanation:
The noble gases are a group of elements of the periodic table that are characterized, in normal conditions of pressure and temperature, for being monoatomic gases without odor, without color and with very low chemical reactivity.
The noble gases encompass the elements of group 18 of the periodic table and include six elements: Helium, Neon, Argon, Krypton, Xenon and Radon.
The noble gases are characterized by complying with the octet rule, that is, they have 8 electrons at their last energy level, with the exception of helium. This complies with the duet rule, because it only has two electrons. In this way the noble gases cannot have more electrons in their last energy level, because this level is already complete and stable. In this way the noble gases have such low reactivity and do not combine with other atoms, also calling them inert gases.
Then, these elements tend to gain or lose electrons easily (option C.) is not true in regard to noble gases.
