Elements can be classified based on their physical states (States of Matter) e. g. gas, solid or liquid. This element is a solid. Lanthanum classified as an element in the Lanthanide series as one of the "Rare Earth Elements" which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. Sulfur is pale yellow, odorless, brittle solid, which is insoluble in water but soluble in carbon disulfide. In every state, whether gas, liquid or solid, elemental sulfur occurs in more than one allotropic form or modification; these present a confusing multitude of forms whose relations are not yet fully understood. State at room temperature Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid as you go down the group. Lanthanum is one of the rare earth elements used to make carbon arc lights which are used in the motion picture industry for studio lighting and projector lights. Lanthanum also makes up about 25% of Misch metal, a material that is used to make flints for lighters.

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).

When isolated in metallic form, silvery white sodium is a violent element, immediately oxidising upon contact with air, and violently producing hydrogen gas which may burst into flame when brought into contact with water. It is one of the highly reactive group one elements that are named the alkali metals.

At room temperature, fluorine is a gas of diatomic molecules, pale yellow when pure (sometimes described as yellow-green). Fluorine condenses into a bright yellow liquid at −188 °C (−306 °F), a transition temperature similar to those of oxygen and nitrogen. Fluorine has two solid forms, α- and β-fluorine.

Worldwide identified reserves in 2017, 2018, 2019 and 2020 were estimated by the US Geological Survey (USGS) to be 14 million, 16 million, 14 million and 17 million tonnes, respectively. An accurate estimate of world lithium reserves is difficult.

Helium (from Greek:? λιος, romanized: Helios, lit. 'Sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.

Nitrogen (N2) is a colorless, odorless and tasteless gas that makes up 78. 09% (by volume) of the air we breathe. It is commonly thought of and used as an inert gas; but it is not truly inert. It forms nitric oxide and nitrogen dioxide with oxygen, ammonia with hydrogen, and nitrogen sulfide with sulfur.

While Chile, China, Argentina and Australia are home to the world's highest lithium reserves, other countries also hold significant amounts of the metal. Other lithium reserves by country Zimbabwe — 70, 000 metric tons. Portugal — 60, 000 metric tons. Brazil — 54, 000 metric tons. United States — 35, 000 metric tons.

Chlorine (Cl2) is a gas at room temperature, but sodium chloride(NaCl) is a solid at room temperature. The melting/boiling point of a substance determines what state of matter it takes at a certain temperature. In Cl2 there are covalent bonds between the atoms forming simple molecules.

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.

If fluorine is absorbed too frequently, it can cause teeth decay, osteoporosis and harm to kidneys, bones, nerves and muscles. Fluorine gas is released in the industries. This gas is very dangerous, as it can cause death at very high concentrations. At low concentrations it causes eye and nose irritations.

F2 and Cl2 are gases at room temperature while Br2 is a liquid and I2 is a. You can ask!

Fluorine. Fluorine is the chemical element in the periodic table that has the symbol F and atomic number 9. Atomic fluorine is univalent and is the most chemically reactive and electronegative of all the elements. In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2.
