It is the lightest element.
Heavy stars produce heavier elements through nuclear fusion in their cores. As heavy stars age and undergo supernova explosions, they release these heavier elements into the surrounding space, enriching it with elements beyond hydrogen and helium. Lighter stars are not massive enough to produce heavy elements through fusion.
The Sun and its planets formed form a huge cloud (disk) of dust which contained both light and heavy elements, but there were more light elements (hydrogen) than heavy. As the disk coalesced into the sun and planets the areas close to the young sun were too hot (heated by the sun) for the light elements to condense and settle onto the young inner planets which are therefore rocky, while the outer planets being further from the sun did accumulate the lighter and more volatile elements. However in the centers of the giant planets there are rocky (heavy) cores.
Heavy water is composed of deuterium, a heavier isotope of hydrogen with an extra neutron. This extra neutron increases the mass of the water molecule, leading to a higher density compared to regular "light" water. This is why it is called heavy water.
Transition metals are often referred to as "heavy metals" due to their high density compared to other elements. They have large atomic masses and many of them are toxic. However, it is important to note that the term "heavy metal" is also used to describe a group of elements with specific properties related to their electronic structure, not just their weight.
Helium is classified as a light element because it has a low atomic mass compared to other elements like oxygen or iron. It is lighter than air, which is why helium-filled balloons float.
Compared to Osmium it is light, compared to Hydrogen it is heavy
The light elements in the universe, such as hydrogen and helium, were created during the Big Bang. Heavy elements, like carbon, oxygen, and iron, were formed in the cores of stars through nuclear fusion processes.
Silver is considered a heavy metal in terms of its density compared to lighter elements like oxygen or carbon. However, it is not as heavy as some other metals like gold or platinum.

Lighter stars are not massive enough to produce heavy elements through fusion.
Heavy water is heavier than light water because instead of both hydrogen atoms in the molecule being ordinary light hydrogen (H - one proton) one or both hydrogen atoms are heavy hydrogen (D - one proton, one neutron).

Compared to a loaf of bread, all nuclear weapons are heavy. Compared to a truck, some are light and some are heavy.
Aristotle
Sodium is considered a light metal in terms of its atomic weight compared to other elements. Its density is less than that of water, so it is not considered heavy in the context of everyday objects or materials.
Type your answer here... The hydrogen atoms in heavy water have a neutron in the nucleus, doubling the mass.
No, hydrogen is a light gas. It is the lightest and simplest element in the periodic table with an atomic number of 1.
