a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound together may vary: covalent bonds and ionic bonds are two common types. The elements are always present in fixed ratios in any compound.
Chemical element, also called element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
is a material made up of two or more different substances which are physically combined.
A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. I
A substance that has a fixed chemical composition throughout is called a pure substance such as water, air, and nitrogen.
hope this help!
Answer:
Here are the definitions of all of them.
Explanation:
Molecule:
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
Compound:
A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound together may vary: covalent bonds and ionic bonds are two common types. The elements are always present in fixed ratios in any compound.
Element:
Chemical element, also called element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
Mixture:
is a material made up of two or more different substances which are physically combined.
Chemical Formula:
A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. I
Pure substance:
A substance that has a fixed chemical composition throughout is called a pure substance such as water, air, and nitrogen.
