What element is the heaviest lightest?
The lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol.
Which is the lightest particle in the periodic table?
electron
electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

What is the lightest liquid?
The order of the liquids from heaviest to lightest will be syrup, glycerin, water, oil, and then alcohol will be on top.
What is the lightest of all gases?
Helium is the second most abundant element in the universe, after hydrogen. Helium has monatomic molecules, and is the lightest of all gases except hydrogen. . Helium, like the other noble gases, is chemically inert.
Is iron a light element?
Iron is the heaviest element formed in the cores of stars, according to JPL. Elements heavier than iron can only be created when high mass stars explode (supernovae). The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe.
What is the fifth lightest element?
In general, heavier elements are rare and light elements are abundant, but there are three big exceptions: lithium, beryllium, and boron. Yet these three elements are the 3rd, 4th, and 5th lightest of all.
What are the lightest elements?

Hydrogen is the lightest and most common element in the universe, consisting of just a single proton and a single electron, with the chemical symbol H. – Helium. – Lithium. – Beryllium.
What is the first lightest element?
Description. The lightest chemical elements are hydrogen and helium, both created by Big Bang nucleosynthesis during the first 20 minutes of the universe in a ratio of around 3:1 by mass (or 12:1 by number of atoms), along with tiny traces of the next two elements, lithium and beryllium.
Which is the lightest element?
Hydrogen is the lightest and most common element in the universe, consisting of just a single proton and a single electron, with the chemical symbol H. It is colorless and odorless, and exists as a gas at everyday temperatures.
