Question

What element makes up most of the weight of water and about half the weight of most rocks?

Answer 1

The element that makes up most of the weight of water and about half the weight of most rocks is oxygen. Oxygen has an atomic number of 8 and is a highly reactive non-metal that is part of the chalcogen group on the periodic table. It is crucial for life as we know it and is found in many different compounds such as water, carbon dioxide, and many minerals.

Answer 2

Oxygen is the element that makes up most of the weight of water and about half the weight of most rocks. Oxygen is the most abundant element in the Earth's crust, making up about 46% of the Earth's total mass.

Answer 3

The element you're referring to is oxygen. Oxygen is a vital component of the human body, making up a significant portion of the body's weight due to its presence in water, proteins, carbohydrates, and fats. Additionally, oxygen is a major component of Earth's crust, forming minerals and rocks. The most abundant minerals on Earth, like silicates, also contain oxygen. So, oxygen plays a crucial role both in the composition of the human body and the Earth's crust.

Answer 4

The element that constitutes the majority of the weight in water and approximately half the weight in most rocks is oxygen.

 Oxygen is the element that makes up most of the weight of water and about half the weight of most rocks.
