No Hydrogen is highly unstable and reactive. This is because its valency is 1 e- i.e. it will gain an electron to fulfill its duplet(it is that state when the outermost orbit has 2 e-). Deuterium is an isotope of hydrogen which is again very unstable although its duplet is fulfilled the reason for this is not known to me.
Neon is chemically unreactive and stable
Noble gases have completely filled orbitals, hence they are stable and chemically inert.
Noble gases, such as helium and neon, belong to the family of elements that are highly unreactive. They have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements.
Chlorine is number 17 on the periodic table, so yes it is stable. It's a poisonous gas and it is NOT unreactive. The main thing that chlorine reacts with is sodium, making sodium chloride, A.K.A. table salt.
Potassium is more reactive than hydrogen. It is a highly reactive metal that reacts violently with water, while hydrogen is a nonmetal gas that is generally unreactive unless under specific conditions.
No. Lithium is highly reactive.
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
Hydrogen, followed by oxygen. Argon is unreactive.
Zinc is unreactive to cold water, but will react with steam to give zinc oxide and hydrogen.
Not all compounds are unreactive. Some compounds are stable and do not readily react with other substances, while others can be highly reactive and form chemical bonds with other compounds. The reactivity of a compound depends on its chemical structure and the conditions under which it is placed.
Its reactivity depends upon the conditions , in acids and alkalies it is highly reactive with pure water and air it is unreactive, although in reactivity series it higher than hydrogen.
Alkali metals are highly reactive and tend to form ionic bonds with other elements, while noble gases are nonreactive and exist as stable, monatomic gases in nature. Alkali metals readily donate an electron to achieve a stable electron configuration, while noble gases already have a full valence shell, making them highly stable and unreactive.
