The most common molecule in a molecular cloud is?
The most common molecule in a molecular cloud is molecular hydrogen (H2).
What is a hydrogen cloud?
A hydrogen cloud is a region in space where a significant amount of hydrogen gas is present. These clouds typically exist in interstellar space and are important for the formation of stars and galaxies. The hydrogen gas in these clouds can be ionized, which makes them visible in certain wavelengths, such as in the H-alpha emission line.
Who proposed the dust cloud theory?
The dust cloud theory was proposed by Fred Whipple in 1950. This theory suggests that comets are made up of icy bodies surrounded by a cloud of dust and gas.
How do you draw a hydrogen?
A hydrogen atom is typically represented simply as an "H" surrounded by a single dot to denote the one electron in its outer shell. This is the simplest way to draw a hydrogen atom in a structural formula.
A(n) is described as a nucleus of protons and neutrons surrounded by an electron cloud.?
Atomic number is the equivalent of the number of protons in an atomic nucleus.
Are comets and asteroids surrounded by hydrogen cloud?
Some comets develop a cloud of hydrogen gas around them when they get close to the sun, due to the sun's radiation breaking apart water molecules in the comet's icy nucleus. This creates a temporary hydrogen cloud known as a coma. Asteroids generally do not have hydrogen clouds since they are composed of rock and metal, lacking the icy material that comets have.
Is a comet surrounded by a hydrogen cloud?
No. A comet is surrounded by various vaporized ices, but not hydrogen.
Is asteroids surrounded by hydrogen clouds?
No, asteroids are rocky, metallic bodies that generally do not have atmospheres or hydrogen clouds surrounding them. Hydrogen clouds are more commonly found in gaseous planets like Jupiter or Saturn.
What planet is surrounded by bright rings of dust and rock?
Asteroids
Which material is found in asteroids helium hydrocarbons hydrogen or water?
Water and hydrocarbons are commonly found in asteroids. Helium and hydrogen are less common, but can also be detected in some asteroids.
Where is a comet located?
Comets are believed to have originated from asteroids in a sort of 'cloud', called the 'Oort Cloud'. It is thought all comets come from the Oort Cloud, which is a cloud of asteroids beyond the Kuiper Belt beyond Neptune. When one asteroid is knocked off from its orbit from the Oort Cloud, it makes really long trips around the Sun, which is why it becomes a comet. All of the asteroids in the Oort Cloud have some type of ice on them, since they are so far away from the sun that everything in the Oort Cloud seems to freeze.
Which nonmetal is surrounded by metals?
hydrogen
What is the internal layering of Jupiter from the center outward?
Jupiter has a core made of rock and metal at its center, surrounded by a layer of metallic hydrogen. Above this is a layer of liquid metallic hydrogen, followed by a layer of molecular hydrogen. The outermost layer consists of clouds of ammonia and water vapor.
The most common molecule in a molecular cloud is?
The most common molecule in a molecular cloud is molecular hydrogen (H2).
What year were asteroids created?
Astroids have not been "created". Astroids are the remains of dead planets and stars that travel through space at speeds of up to 1 million kilometers an hour. Astroids have been around since planets and stars were created.
Where do asteroid came from?
Asteroids are rocky remnants from the early formation of our solar system, originating from the cloud of gas and dust that surrounded the young sun over 4.5 billion years ago. They are mainly found in the asteroid belt between Mars and Jupiter, but can also be found throughout the solar system. Some asteroids have been knocked out of the asteroid belt due to gravitational interactions with larger planets.
What did our sun form from?
A gas cloud (of mostly hydrogen).
