Name the four most common elements?
The four most common elements in the universe are hydrogen, helium, oxygen, and carbon.
Do helium and hydrogen bond together?
Helium does not form chemical bonds with other elements, including hydrogen. Hydrogen, however, can bond with other elements like oxygen, carbon, and nitrogen to form various compounds.
What are the majority of the elements made of?
The majority of elements in the universe are made of hydrogen and helium, with these two elements accounting for about 98% of all atoms. Other elements like carbon, oxygen, and nitrogen make up the remaining percentage.
What are examples of substances that are elements?
Examples of elements are hydrogen, oxygen, carbon, and gold. These substances cannot be broken down into simpler substances by chemical means.
What is the name of gases?
The noble gasses are all elements in the last group in the Periodic Table, starting w/ helium ending w/ radon
How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
Name the four most common elements?
The four most common elements in the universe are hydrogen, helium, oxygen, and carbon.
What elements have been detected in our sun?
The predominant element in the Sun is hydrogen, and then helium: by mass, it is 70% hydrogen, 28% helium, 1.5% carbon, nitrogen and oxygen, and 0.5% all other elements.
Do helium and hydrogen bond together?
Helium does not form chemical bonds with other elements, including hydrogen. Hydrogen, however, can bond with other elements like oxygen, carbon, and nitrogen to form various compounds.
What is an example of elements?
Hydrogen, Helium, Lithium, Berylium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon are the first 10 - there are many more and are in the periodic table

What elements made up the sun and in what percentage?
70 % hydrogen, 28 % Helium, 1.5 % mix of carbon oxygen, & nitrogen, plus 1/2 % of everything else.
Does helium have carbon dioxide in it?
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.
What other elements make up your atmosphere?
Argon, Carbon Dioxide, Neon, Oxygen, Nitrogen, Helium, Methane, Krypton, Hydrogen
What 6 elements make up the earths atmosphere?
The six main elements that make up Earth's atmosphere are nitrogen, oxygen, argon, carbon dioxide, neon, and helium. Nitrogen and oxygen are the most abundant, making up about 99% of the atmosphere.
What do astronomers consider heavy elements?
Astronomers consider elements beyond hydrogen and helium, such as carbon, oxygen, nitrogen, and iron, as heavy elements. These elements are created through processes like nuclear fusion in stars and supernova explosions.
