The most abundant element in the universe is hydrogen, which makes up about 3/4 of all matter. Helium makes up most of the remaining 25%. Oxygen is the third most abundant element in the universe.
The basic material that makes up all matter and is different from any other in its atomic structure is the element. Each element is defined by the number of protons in its nucleus, which determines its unique atomic number.
The most abundant element in the universe is hydrogen, which makes up about three-quarters of all matter! Helium makes up most of the remaining 25%
Hydrogen is the most common element in our galaxy.
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
Carbon is an essential element that makes up a large part of all living matter. It is the key component in organic molecules such as carbohydrates, proteins, lipids, and nucleic acids, which are essential for life processes.
