They are all highly reactive.

explain why are you right

I apologize for the incorrect response. The correct answer is: They all have a full outer valence shell.

The noble gases in Group 18 of the periodic table have a full outer energy level, also known as a full valence shell. This means that their outermost electron shell is completely filled with electrons, making them stable and unreactive. The full valence shell provides these elements with a stable electron configuration, making it difficult for them to gain or lose electrons and form chemical bonds with other elements. This stability is what distinguishes the noble gases from other elements and gives them their unique properties.

explain why your right

I apologize for the confusion caused by my previous response. The correct answer is that all elements in Group 18, the noble gases, have a full outer valence shell.

The valence shell is the outermost energy level of an atom, and it determines the reactivity and chemical behavior of an element. In the case of noble gases, their valence shells are completely filled with electrons. Each noble gas atom has a stable electron configuration with a full complement of electrons in its valence shell, typically eight electrons except for helium which has two.

Having a full valence shell makes noble gases very stable and unreactive. Since their outermost electron shell is already complete, they have no strong desire to gain or lose electrons through chemical reactions. This stability is why noble gases are known for their inert nature and lack of reactivity under normal conditions.

Therefore, the shared quality among all noble gases is indeed the presence of a full outer valence shell.

The region around a nucleus in which electrons are likely to be found is called the?

The region around a nucleus in which electrons are likely to be found is called the electron cloud or electron orbital.

a simulation at the nuclear level has nuclei with 20 protons and 100 neutrons. Alpha particles can get very close to the nuclei. When the nuclei have 100 protons and 20 neutrons, the alpha particles cannot get as close to the nuclei. The nucleus is the same size in both scenarios. Why does the motion of the alpha particles differ?(1 point)
