the apperence of hydrogen is colourless, with a hexogonal crystal structure
Fluorine in its pure form at room temperature is a pale yellow gas. It is highly reactive and is never found in its elemental form in nature, but rather as compounds with other elements.
Hydrogen is the lightest and simplest element, making it very easy to compress and manipulate. In its pure form, hydrogen is a gas at room temperature and pressure.
Sodium in its pure form at room temperature appears as a shiny, soft, and silvery-white metal. It is highly reactive and easily tarnishes when exposed to air, forming a dull oxide layer on its surface.
Calcium is a solid, soft dull grey metal at room temperature :)
No, Hydrogen peroxide is a compound the chemical formula H2O2. Hydrogen and element and is shown as either H or H2. Hydrogen is a gas at room temperature while hydrogen peroxide is a liquid, and is used in hospitals.

The answer would be no. In Earth there is no hydrogen source in its pure form. It is only found in compound with other elements.
Hydrogen in its pure state is H2 gas, which is neutral. The ionic form, H+, is acidic.
ok well pure fluorine is coloured pale yellow, it is a highly corrosive and poisonous gas. it has a vitreous and dull lustre. at room temperature it is a gas.
Hydrogen is a colorless, odorless, and tasteless gas at room temperature. It is the lightest and most abundant element in the universe. In its pure form, hydrogen molecules consist of two hydrogen atoms bonded together.
No. When in the form of water, hydrogen and oxygen form a compound, which is a pure substance.
Answer this question… One problem with fuel-cell cars is that ________ gas is not readily available in pure form.
