The lightest element would be helium
Hydrogen is the lightest substance among these four elements. It has the lowest atomic number and atomic weight, making it the lightest element on the periodic table.
The element that has the lowest boiling point (turns into a gas at the lowest temperature) is Helium (He). Helium, depending on the isotope, turns into a gas at either 4.2K or 3.2K. This is -268.8 and -269.8 celcius respectively.
Helium is a gas at room temperature.
Helium is from the Greek word, Helios, meaning 'the sun'.
No, it is a colorless, highly flammable gaseous element, the lightest of all gases and the most abundant element in the universe.
Hydrogen is the lightest gas.
gas is the lightest in weight
Helium but it is noble gas. Lithium is the lightest solid element that found in natural form.
The lightest diatomic element is hydrogen (H2). It has a molecular weight of approximately 2 grams per mole, which is the lightest of all the elements.
The lightest metal element is lithium, with an atomic number of 3 and an atomic weight of around 6.94. It is also the lightest metal that is a solid at room temperature and is commonly used in batteries and other electronic devices.
Hydrogen, at 1.0079
The state of matter of hydrogen, which is the lightest element, is that of a gas at room temperature. Hydrogen also is very flammable gas.
Hydrogen is the lightest of all elements and is extremely flammable. It is also the most plentiful gas in the universe.
the simplest element. Hydrogen is a gas, a non-metal, it is the lightest element.
Hydrogen is a gas, a non-metal, it is the lightest element.
Helium with an atomic number of 2,is the lightest gas on the Periodic Table :)
