At standard temperature and pressure there are 11 which are gasses. They are: hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), chlorine (Cl), helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn)..
Also question is, what are the 11 elements that are gases at room temperature?
Thus the gaseous elements are, in order, Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Neon, Chlorine, Argon, Krypton, Xenon, Radon.
Similarly, which elements are solids liquids and gases? Phase of the elements
| Hydrogen | Gas | Solid |
| Radon | Gas | Solid |
| Bromine | Liquid | Solid |
| Mercury | Liquid | Solid |
| Lithium | Solid | Solid |
In this way, which elements are gases in the periodic table?
The gaseous element group; hydrogen (H), nitogen (N), oxygen (O), fluorine (F), chlorine (Cl) and noble gases helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn) are gases at standard temperature and pressure (STP).
How many elements naturally occur as a gas?
Although more than one hundred elements exist; only two naturally occur in the liquid state. All other liquids are compounds. The two liquid elements are bromine and mercury. Many elements naturally occur as gases: hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases (Group VIIIA elements).

Is carbon a gas?
Carbon is classified as an element in the 'non-metals' section which can be located in groups 14,15 and 16 of the Periodic Table. Non-metallic elements exist, at room temperature, in two of the three states of matter: gases (Oxygen, Hydrogen & Nitrogen) and solids (Carbon, Phosphorus, Sulfur and Selenium).Who discovered halogens?
Scheele called the element "dephlogisticated muriatic acid", which is how chlorine was known for 33 years. In 1807, Humphry Davy investigated chlorine and discovered that it is an actual element.What are all the diatomic elements?
There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine.Are noble gases stable?
Noble gas. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.What are the 7 noble gases?
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).Who discovered noble gases?
William Ramsay
Is gas an element?
"Oxygen gas" is not an element. It is a compound (more specifically, it is a molecule or collection of molecules). "Oxygen" by itself can refer to the element oxygen, the oxygen atom, or the oxygen molecule O2.Which elements are most reactive?
Cesium and francium are the most reactive elements in this group.What elements are liquids?
The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.Are halogens gases?
The halogens exist, at room temperature, in all three states of matter: Solid- Iodine, Astatine. Liquid- Bromine. Gas- Fluorine, Chlorine.How many inert gases are there?

How many gases are there?
How many gases are present in the air? The cocoon of gas that surrounds the planet is generally constant. Essentially three gases comprise 99% of the atmosphere: nitrogen, oxygen and argon, each with respective compositions of 78%, 20%, and 1%. The remaining 1% has a small variable.Is K solid liquid or gas?
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Potassium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table.Is mercury a liquid?
Mercury is the only metal that is a liquid at normal temperatures and pressure. Because of the behavior of the valence electrons, mercury has a low melting point, is a poor electrical and thermal conductor, and doesn't form diatomic mercury molecules in the gas phase.
