Hydrogen and oxygen
Water is the most common molecule, between 55 and 65% of our mass.
Hydrogen accounts for 63% of our atoms, but oxygen accounts for 65% of our mass.
(Both hydrogen and oxygen are part of many other molecules besides water.)

How does two elements make a compound?
After a chemical reaction two elements form a chemical compound.
Look at the diagram below. It shows the common elements found in the human body.Elements 1 and 3 are used to make the most common substance in the body. What are these elements?
Oxygen and hydrogen
Do two element mixed make a element or a compound?
2 elements make a compound.
How do the properties of a compound compare with the properties of the elements that make up the compound?
The properties of a compound are different from those of the elements that make it up. Compounds have unique physical and chemical properties that arise from the way the elements are bonded together, whereas the properties of individual elements are based on their atomic structure. Mixing elements together to form a compound can result in properties that are entirely different from those of the individual elements.
Do a compound made up of just two elements joined together?
eve three elements can make a compound .
What elements make up common table salts?
Normally, sodium and chlorine are the most common but potassium and chlorine is a "salt" as well. The common rule is that elements of the halogen family and the alkali family form "salt" compounds.
What are the most common elements in the human body?
Carbon. the human boddy also contains a very small amount of gold too.
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
When elements chemically bond together they make a?
compound. A compound is a substance formed when two or more elements are chemically bonded together in specific ratios.
Can you predict the properties of a compound by knowing the properties of the elements that make up the compound explain your answer?
Yes, you can predict the properties of a compound based on the properties of the elements it is composed of. This is because the properties of a compound are determined by how its constituent elements interact with each other through chemical bonds. For example, if the elements in a compound have high electronegativity, the compound is likely to have polar covalent bonds and exhibit properties like high solubility in water and good conductivity.
When two elements combine does it make a compound?
Yes
How is a compound different from the elements that make it up?
A compound is different from the elements that make it up because it is a new substance with unique properties that are not present in the individual elements. When elements combine to form a compound, they undergo a chemical reaction that results in a new arrangement of atoms and different chemical properties.
