Plutonium is a high-density metal, hydrogen a low-density gas.
Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.
Not much. Helium is an inert gas. It does not want to react with anything. Plutonium is highly radioactive, and some of its isotopes are fissile. In any case, the two would not react. Nothing nuclear is going to happen beased on the mixing of the two elements. The only possible problem is if a critical mass of plutonium is gathered together. Then a criticality incident will occur and a radioactive mess will result with the release of a cloud of airborne and highly radioactive nuclides.
Hydrogen is lighter than Oxygen. This is a very simple question. Hydrogen is the first element on the periodic table of elements and it weighs 0.08988 grams per litre. Oxygen is the 8th element on the periodic table. It weighs 1.429 grams per litre. All of the elements (and most chemicals you will ever want to know about) have an article on Wikipedia. These articles almost always include the "weight per amount" known as Density.
No, francium is larger than hydrogen. Francium is a much heavier element located at the bottom of the periodic table, whereas hydrogen is the lightest element. Size of an atom generally increases as you move down a group in the periodic table.
Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.
oxygen gas is heavier than hydrogen gas
Plutonium is heavier than gold. It is a dense, radioactive metal that is commonly used in nuclear reactors and weapons.
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
hydrogen
Heavier but safer. Look what happened to the Hindenburg:(
A carbon atom is about 12 times heavier than a hydrogen atom, while a calcium atom is about 40 times heavier than a hydrogen atom. Therefore, carbon atoms are 12 times heavier than hydrogen atoms, and calcium atoms are 40 times heavier than hydrogen atoms.
No.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
Tritium is lighter than deuterium. Tritium is a hydrogen isotope with one proton and two neutrons, making it heavier than regular hydrogen but lighter than deuterium, which has one proton and one neutron.
Mass of Hydrogen gas:- 2g/mol Mass of Oxygen gas :- 32g/mol Therefore, Oxygen gas is more heavier
Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.
H2S (hydrogen sulfide) is heavier than CH4 (methane) because the molar mass of sulfur (S) is greater than the molar mass of carbon (C). This difference in molar masses results in hydrogen sulfide being denser and therefore heavier than methane.
