how many atoms in the sun

Be sure to include the algebraic sign (+ or -) in your answer. Now we have more room. On Earth - atoms generally consist of a nucleus surrounded by the one more atoms. Stars make up most of the visible mass of the universe, so we need to determine how many atoms are in a star. Under the given assumptions (a) Assume that all of the atoms in the universe are hydrogen atoms in stars. In the center of the atom, the protons and neutrons gather to form the nucleus, while the electrons zip around that nucleus as if they are minute planets orbiting their own little sun [source: Northwestern]. – Calculations of how many atoms are in the Sun and how much energy per atom combustion produced gives the Sun a lifespan of about 10,000 years. Iron atoms have been detected in the sun's atmosphere, some with many of their electrons stripped away. To calculate the number of atoms in a sample, you need to find how many moles of the element the sample contains. Matter is made up by atoms (formed by protons and other subatomic particles).When the environment is right, atoms can join together and form molecules, which give rise to most materials studied in materials science.But certain environments, such as high temperatures, don't allow atoms to form molecules. Background. Series following intrepid expats as they chase a dream life The mass of an object is a measure of how much material the object has. The quick answer is: more than you can count! I'm sure an actual physicist would know a more precise answer. When an atom is in an excited state, the electron can drop all the way to the ground state in one go, or stop on the way in an intermediate level. The mass of a hydrogen atom is about 2x10^-27 kg. (b) Assume that the sun is a typical star composed of pure hydrogen with a density of 1.4gcm^-3 and a radius of 7xx10^8m. 1. The Sun is mostly made of hydrogen. Hello! The number is so gigantic that they have to make an analogy: Imagine that the grapefruit were the size of the earth! (ex:!In!3H 2O,!the! 1gram /6.02 x 10^23 or 1 kg / 6.02 x 10^26 "The sun is mostly made of Hydrogen and has a mass of about 2x10^30 kg. Question: How Many Atoms Are In The Sun If It Is Assumed The Sun Is Composed Of Only Molecular Hydrogen And Has A Density Of 1.42 G/cm? How many Hydrogen atoms are in the sun?" Stars have very high temperatures, primarily in their interior, and … Atoms are the building blocks of matter. Q) The mass of the sun is 1.99 x 10^30 kg, and the mass of an atom of hydrogen, of which the Sun is mostly composed, is 1.67 x 10^-27 kg. ×Again, the Earth is older than that, so this cannot be the source of the Sun’s energy. How many atoms are there in the world? A mole is a unit chemists use. What is the net electric charge (in coulombs) of an iron atom with 26 protons and 11 electrons? Changes in Composition Earth's primordial atmosphere was probably similar to the gas cloud that created the sun and planets. (And for every helium atom formed, roughly a trillion photons are emitted from the sun's surface. Each hydrogen atom has a mass, m H = 1.67 x 10-24 grams. The Radius Of The Sun Is Estimated To Be 7x108 M And Its Volume Can Be Found From V = Nr? 3] Atoms in the Sun: Approximately, how many atoms are there in the Sun? (c) Assume that each of the roughly 100 billion stars in the Milky Way galaxy contains the same number of atoms as our sun. Specifically, in core of stars that are about the size of the Sun, energy is produced when hydrogen atoms (H) convert and become helium (He). How many atoms are in the sun? I have a feeling this is a really easy problem, but I'm too rusty to know what to do. Compare the nuclei of atoms on Earth with those in the sun's core. A human body weighing 154 pounds (70 kilograms) is comprised of 7 billion billion billion atoms, which is a 7 followed by 27 zeros. Looking at this with some estimated mathematics, hopefully this can give you a ball park answer. The Sun's mass is very close to 2 x 10^30 kg. During … HOW TO COUNT ATOMS Background+Information:+ • subscripts!–!the!little!numbers!thattell!how!many!atoms!there!are!! The mass of the earth is 5.98*10 27 grams. Calculate the number of hydrogen atoms in our Sun given that the radius of the Sun is 7 × 10 8 m and its density is 1 .4 g/cm 3 . Such reactions—which occur in the Sun 100 million quadrillion quadrillion times each second—release a significant quantity of energy as predicted by E=mc 2 . If you assume that this is entirely Hydrogen (not really correct, but good enough for a back-of-envelope calculation) then you can quickly find that a single atom of Hydrogen has a mass of . It's equal to Avogadro's number (6.02 X 10 23) of atoms.By definition, the weight of one mole of an element (its molar mass) is … The mass of the Sun is M sun = 2 x 10 33 grams. gas atoms and many kinds of molecules. Stars are primarily composed of hydrogen atoms and our Sun is an average-sized star. They, quite literally, make our universe what it is. In the sun's core - energy and pressure strip electrons away from the atomic nuclei. The Sun is fueled by a process known as fusion: four hydrogen atoms undergo a series of collisions and eventually fuse together to form one helium atom. If you thought of each atom as the size of a blueberry, then you would have to fill the entire earth up with blueberries to make one grapefruit. There was no molecular oxygen or other reactive oxides. Here the creators imagine how many atoms would be in a grapefruit. The sun has so much mass, that it has incredibly strong gravity and magnetic fields that cause nuclear fusion to occur in the sun´s core. • No chemical reaction can be the source of the Sun’s energy! This was a reducing atmosphere. But we can get an estimate of the number of atoms in the earth by first knowing what its mass is. It consisted of hydrogen and helium, along with methane, ammonia, and water. Overall, nuclear fusion in our sun combines two hydrogen atoms (the smallest and lightest atoms) together to form one helium atom (a slightly larger atom). Every second, the sun converts about 500 million tons of hydrogen into helium. Real atoms, even a relatively simple ones like hydrogen, have many different orbitals, and so there are many possible energies with different initial and final states. N atoms ~ M sun / m H ~ [2 x 10 33 g] / [1.67 x 10-24 g] ~ 1.2 x 10 57 atoms of hydrogen (H) 4] Atoms in your body. H D - Lady Po 7x 10!m Vitry3 Cm²
