The sun's composition is dominated by two primary chemical elements, which together account for more than 98 percent of its mass. Hydrogen, the lightest and most abundant element in the universe, makes up approximately 74 percent of the sun's mass. Helium, the second lightest element, comprises about 24 percent of the sun's mass, bringing the total to 98 percent. The remaining 2 percent consists of various heavier elements, including oxygen, carbon, nitrogen, and iron, among others.
A chemical containing two or more elements in the molecule.
This is a chemical reaction.
This is a chemical compound.
I'm pretty sure is is a Compound. A compound is a substance that is made up of more than on element. The properties of matter mostly depend on how atoms of different elements are combined in compounds.
These elements have more or less similar chemical properties.
yes
no both iron and silicon are elements. chemical compounds aretwo or more elements.
A chemical containing two or more elements in the molecule.
A chemical containing two or more elements in the molecule.
A combination of two or more elements is called a compound. These elements are held together by chemical bonds and can be separated using chemical reaction.
A compound is a combination of two or more elements. These elements join together based on their molecular bonds. No two elements combine in the same percentage.
This is a chemical reaction.
This is a chemical compound.
A chemical compound contain two or more different chemical elements.An element is made up of one type of atom. Compounds are made of two or more different chemical elements that are chemicaly joined (bonded) together. Basically speaking, chemical elements are the building blocks of chemical compounds.The elements can be thought of as the letters of the chemical alphabet, with which compounds which can be thought of as the words of the chemical languageare written.
A compound is the substance formed by the chemical combination of two or more elements in definite proportions. It has a unique chemical structure and properties different from its constituent elements.
Elements form molecules of chemical compounds
- allowed rational ordering of chemical elements- predicted the properties of unknown elements- the chemical behavior of chemical elements can be predicted- the atomic radius can be predicted- the melting point can be predictedand more
