Question

What are neutral gases?
A. Has 8 valence electrons in its outer level
B. Has higher reactivity
C. They accept protons
D. They have low pH

Answer 1

Hint: Neon, which consists of only one shell, reaches the noble gas configuration with its valence electrons. Find out these valence electrons and you will be able to figure out the answer.

Complete answer:
A neutral gas is always stable, which means it's already having 8 electrons in its outer level. Due to which they don't have to throw any reactions in order to get stable. These gases are also called inert gases. Inert comes from the Latin which means stagnant and non-reactive. Nitrogen is an inert gas. It does not react under normal conditions. These gases are usually used to avoid unwanted chemical reactions degrading a sample. These unwanted chemical reactions are nothing but oxidation and hydrolysis reactions with oxygen and moisture in the air.
Scientists consider that as due to having 8 electrons in their outermost shell, and the ionization energy of these atoms are very high and their electron affinities are very low. An octet's rule had been invented as, in chemical reactions, atoms share, accept or gain electrons to achieve eight electrons in their Valence shell or to achieve the outer shell configuration of the nearest noble gas. However, this rule is justified for elements of the second row in the periodic table, whose outermost- shell capacity is 8 electrons.

Therefore, neutral gases will have 8 electrons in its outer level.
Option A is your answer.

Note: Do not get confused with inert gases and Noble gases. Noble gases belong to the 18th group of the periodic table. They are called inert gases because they are stable and non-reactive.
