What two chemical elements make up the majority of our sun
What 2 elements make up most of the sun’s mass?
The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 92.1% hydrogen and 7.9% helium. Various metals make up less than 0.1% of the mass of the sun.
What elements make up majority of the sun?

|---|---|---|
| Hydrogen | 91.2 | 71.0 |
| Helium | 8.7 | 27.1 |
| Oxygen | 0.078 | 0.97 |

What 2 things are the sun mostly made of?
The sun is not a solid mass. It does not have easily identifiable boundaries like rocky planets like Earth. Instead, the sun is composed of layers made up almost entirely of hydrogen and helium.
What is the chemical composition for the sun?
| Chemical composition of the Sun | |
|---|---|
| Hydrogen | 73% |
| Helium | 25% |
| Oxygen | 0.80% |
| Carbon | 0.36% |
What 2 elements make up most of the sun’s mass quizlet?
What 2 elements make up most of the Sun’s mass? Helium and hydrogen.
What elements in the sun are fused together in the sun?
In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom.
What is the Sun’s surface made of?
The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.
Which two elements make up the Sun quizlet?
The Sun is mostly composed of hydrogen and helium. By mass the composition of the Sun is 75% hydrogen and 25% helium. Metals make up less than 0.1% of the mass of the Sun. The temperature of the Sun’s temperature is about 10,340 Fahrenheit.
What is the process that generates energy in the Sun?
nuclear fusion
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Which of the following are parts of the Sun’s atmosphere?
The sun’s atmosphere: Photosphere, chromosphere and corona.
Which two elements are most abundant in Earth’s crust?
Look at the properties of Oxygen and Silicon – the two most abundant elements in the Earth’s crust – by clicking on their symbols on the Periodic Table.
What are the two most abundant elements in the universe?
Together, helium and hydrogen make up 99.9 percent of known matter in the universe, according to Encyclopedia.com.
Why does the sun emit neutrinos?
Neutrinos are born during the process of nuclear fusion in the sun. In fusion, protons (the nucleus from the simplest element, hydrogen) fuse together to form a heavier element, helium. This releases neutrinos and energy that will eventually reach Earth as light and heat.
Which two chemical elements are the most frequent in the Earth’s crust and what is their form?
Silicon and oxygen are the two most common chemical elements in the crust that also happen to like each others company very much. Pure silicon oxide is known as mineral quartz which makes up 12% of the crust. There is not a single common non-silicate mineral that contains silicon — silicon always combines with oxygen.
What elements is the Earth mostly made of?
The mass of the Earth is approximately 5.98×1024 kg. In bulk, by mass, it is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%); with the remaining 1.2% consisting of trace amounts of other elements.
What are neutrinos and how are they produced in the Sun?
Neutrinos are born during the process of nuclear fusion in the sun. In fusion, protons (the nucleus from the simplest element, hydrogen) fuse together to form a heavier element, helium. This releases neutrinos and energy that will eventually reach Earth as light and heat.
How is a neutrino formed?
Neutrinos are the most abundant particles that have mass in the universe. Every time atomic nuclei come together (like in the sun) or break apart (like in a nuclear reactor), they produce neutrinos. Even a banana emits neutrinos—they come from the natural radioactivity of the potassium in the fruit.
What is neutrino flux?
In 2013, IceCube discovered neutrinos of extragalactic origin. A measurement of the intensity of such a neutrino stream is known as a neutrino flux.
What are neutrinos made of?
A neutrino is a particle!
It’s one of the so-called fundamental particles, which means it isn’t made of any smaller pieces, at least that we know of. Neutrinos are members of the same group as the most famous fundamental particle, the electron (which is powering the device you’re reading this on right now).
What is neutrino oscillation also explain the solar neutrino problem?
Neutrino oscillation is a quantum mechanical phenomenon in which a neutrino created with a specific lepton family number (“lepton flavor”: electron, muon, or tau) can later be measured to have a different lepton family number.
What particles come from the Sun?
Summary: The sun not only radiates light all over the place, but it also emits millions of tiny invisible particles called neutrinos.
What is positron and neutrino?
The positron is a positively charged electron having the symbols ₊₁e⁰, e⁺ and β⁺, the symbol for electron being ₋₁e⁰, e⁻ and β⁻. The neutrino is a tiny, electrically neutral particle, ejected along with β particle during nuclear fission and carry around 5% of the total energy produced in fission.
