You cant. It is an element and thus making it heavier would mean it is no longer hydrogen. However, heavy hydrogen exists and is called deuterium and is made in nuclear reactors.
Helium is heavier.
oxygen gas is heavier than hydrogen gas
Nitrogen, has a atomic weight roughly 14 times heavier then that of hydrogen.
Heavier but safer. Look what happened to the Hindenburg:(
Carbon
The sun fuses hydrogen to make helium. It will be several billion years before the sun fuses helium to make heavier elements.
Heavier H2S refers to the isotope of hydrogen, known as deuterium, which contains one neutron in addition to the proton found in regular hydrogen. Deuterium is heavier than ordinary hydrogen because of the added neutron.
Hydrogen and Helium. Also comprised of a core of much heavier elements, all the elements in the universe heavier than hydrogen probably came from supernovae.
hydrogen
Some of the hydrogen has been converted into heavier elements by stars.
Plutonium is a high-density metal, hydrogen a low-density gas.
Objects are not made of forces. A star is made of hydrogen, helium and, later in its life, heavier elements.
