oxygen
The most abundant element where? It is the most abundant element in Earth's crust. The most abundant element on planet Earth, on the other hand, is iron, while the most abundant element in the Universe is hydrogen.
Hydrogen is the element that makes up most of the detectable mass in the universe. About 75% of the normal matter in the universe is hydrogen.
If you mean the most common element it is hydrogen.
The element in period 2 with the most mass is Neon (Ne).
The Sun is composed of about 71% hydrogen by mass. This makes hydrogen the most abundant element in the Sun.
based on our fundemental constituant being Carbon and its adherance to oxygen as CO2 and Hydrogen H2O (being 70% approx of body mass), then on mass is would be Oxygen.
The predominant element in the human body is oxygen, which makes up approximately 65% of the body's mass. This essential element is found in compounds like water and plays a crucial role in respiration and energy production.
Me and thee are mainly water, so hydrogen will be the most abundant in terms of number of atoms. However, by mass the body is mostly oxygen.
The most abundant element in the universe is hydrogen. It makes up about 74% of normal matter by mass.
In number of atoms (element) hydrogen is the most abundant, not in mass.
Hydrogen is the most common element in our galaxy.
Hydrogen is the most abundant element and makes up 99.8% of the Solar System.
Calcium provides about 1.4-1.6 % of the mass of the human body. It is only .24 % of total number of atoms, but it weighs more than most. An adult person has about a kilogram of calcium in their body.
Oxygen is the most abundant element in the dry weight of humans, making up about 65% of our body mass.
If you are wondering by weight, it is: OXYGENIf you are wondering by number of atoms it is: HYDROGENIf you might wanna know, or more info...Here is this:The MOST abundant element in the human body is oxygen. It cover about two thirds. (Around 65% (in percentage) If you are looking by mass.
CARBON
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
