Matter is made of atoms, vast collections of atoms.
Differences in matter are due to different amounts of protons and neutrons in the atom. Elements are distinguished by the number of protons, whereas isotopes (same element but different mass) are determined by the number of neutrons.
What else can I help you with?
What gas is the universe most visible of?
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
How much is outer space mass?
The total mass of outer space, often referred to as the mass of the universe, is estimated to be around (1.5 \times 10^{53}) kg. This includes both visible matter, such as stars and galaxies, and dark matter, which makes up about 27% of the universe's total mass-energy content. Additionally, dark energy constitutes about 68% of the universe, contributing to its overall dynamics but not its mass in the conventional sense. However, precise measurements remain challenging due to the vastness and complexity of the universe.
What is the weight of all the mass in the universe?
The total mass of the universe is estimated to be about 10^53 kilograms, which includes both visible matter (like stars and galaxies) and dark matter. However, the weight of the universe is not typically defined since weight depends on the gravitational force acting on mass, which varies depending on location. Additionally, dark energy, which makes up about 68% of the universe, complicates calculations as it does not have mass in the conventional sense. Thus, while mass can be estimated, the concept of weight is less applicable on a cosmic scale.
What element is there most of?
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
What percentage of water is there in the universe?
Water makes up about 0.0001% of the total mass of the universe. This includes water vapor in the atmosphere, water in comets, asteroids, and icy planets.
What gas is the universe most visible of?
The most abundant gas in the universe is hydrogen. Hydrogen atoms make up about 75% of the universe's elemental mass.
What Matter in the universe that is undetectable but has mass is called?
Dark matter. It is theorized to make up approximately 27% of the universe's total mass-energy content. Its presence is inferred from its gravitational effects on visible matter.
What element makes up most of the detectable mass in the universe?
Hydrogen is the element that makes up most of the detectable mass in the universe. About 75% of the normal matter in the universe is hydrogen.
How much is outer space mass?

How many percentage of the universe is hydrogen?
Hydrogen makes up about 75% of the universe by mass. It is the most abundant element in the universe and can be found in stars, gas clouds, and planets.
What is the percentage of aluminum the universe?
Of all the baryonic matter, aluminium makes up about 0.005%. Considering that ordinary baryonic matter makes up about 4.9% of the universe, that would make aluminium constitute about 0.049 x 0.00005 = 0.000000245% of the mass of the universe.
Which makes up most------single elements or compounds?
In terms of the total mass of the universe, it is single elements.
What element is there most of?
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
What state of matter is most abundant in space?
Plasma. It makes up more than 99% of visible matter in the universe, and most of the invisible matter.
What percentage of water is there in the universe?
Water makes up about 0.0001% of the total mass of the universe. This includes water vapor in the atmosphere, water in comets, asteroids, and icy planets.
Plasma makes up about how much of the visible universe?
If you define the "visible universe" as objects emitting light or electromagnetic radiation that can be seen or visualized from earth, then plasma makes up essentially all of it.In our solar system, the sun which is more massive than all the planets is made up almost entirely of plasma. Of course, the planets with perhaps the exception of the gas giants are made up of normal matter. But, they are just a tiny drop in the universe. We are unable to see planets in any of the other billions of solar systems. A few planets have been postulated, but are essentially invisible from earth.Even if we assumed every star had planets like our sun, the mass of these planets would be negligible.If you include all the blackness of space, then it is probably mostly void of matter, although the matter that is there would still be ions and plasma.
