What are the most common elements in the universe?
Hydrogen is the most abundant element in the universe, accounting for about 75 percent of its normal matter, and was created in the Big Bang. Helium is an element, usually in the form of a gas, that consists of a nucleus of two protons and two neutrons surrounded by two electrons.
What are the eight most common elements in the universe?
In the right image, hydrogen is the most abundant element in the universe, followed by helium, oxygen, carbon, neon, nitrogen, magnesium, The abundance of hydrogen and helium, i.e. the lightest elementwith an atomic number 1 and 2, dominates the other elements that are rare compared to them.
What are the 4 most common elements in the universe?

What is the hardest element to find?
“At” stands for astatine. It is an element with 85 protons packed into its nucleus, thus the atomic number “85” The problem is, there’s something about 85 protons in a tight space that nature doesn’t enjoy. Almost as soon as they squeeze together bits of nuclear material get spat out, or get added, and poof!
What are the most common elements on Earth?
The most abundant element in the earth’s crust is oxygen, making up 46.6% of the earth’s mass. Silicon is the second most abundant element (27.7%), followed by aluminum (8.1%), iron (5.0%), calcium (3.6%), sodium (2.8%), potassium (2.6%).
What is the most common element?
Vote for this answer. On earth, oxygen is the most common element, making up about 47% of the earth’s mass. Silicon is second, making up 28%, followed by aluminum (8%), iron (5%), magnesium (2%), calcium (4%), sodium (3%), and potassium (3%). All of the remaining elements together make up less than 1% of the earth’s mass.
What is the percentage of elements in the universe?
The Universe. The universe is dominated by the elements hydrogen 83%, and helium 16%. Other elements in the universe are oxygen 0.1%, carbon 0.03%, nitrogen 0.01%, silicon magnesium and neon are all about 0.003% of the elements in the universe.
What elements are found in space?
While hydrogen and helium make up most of the gases in interstellar space, tiny traces of other elements such as carbon, oxygen and iron also exist. Scientists who study interstellar space use spectrometers to identify trace amounts of other molecules between the stars.
