Elements combine to form chemical compounds that are often divided into two categories.
Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.
Equation
Nonmetals combine with each other to form covalent compounds, which exist as neutral molecules.
Equation
The shorthand notation for a compound describes the number of atoms of each element, which is indicated by a subscript written after the symbol for the element. By convention, no subscript is written when a molecule contains only one atom of an element. Thus, water is H2O and carbon dioxide is CO2.
Explanation:
Element: An Element is a substance made up of only one type of atom as like gold, copper, oxygen, etc.
Compound: A compound is a substance that consists of two or more elements, for example-water, carbon dioxide, etc.
Mixture: A mixture is a substance which is made up of several elements.
