What is a substance made of 2 or more elements chemically combined?
Compound : A substance made of two or more elements that are chemically combined in fixed amounts. Periodic Table of Elements : A table in which all the known elements are arranged by properties and are represented by one or two letters, referred to as chemical symbols.
Is a substance made up of atoms of two or more elements joined by chemical bonds?

When a substance is made of two or more atoms like this we call it?
compound
When two or more atoms join together, we call it a molecule. When two or more atoms of different elements join together, we call it a compound.
When two or more atoms from different elements join They form a?
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.
When two or more atoms join together by sharing their outermost electrons?
A covalent bond thus holds two atoms close together because electrons in their outermost orbitals are shared by both atoms. These atoms readily form covalent bonds with other atoms and rarely exist as isolated entities. As a rule, each type of atom forms a characteristic number of covalent bonds with other atoms.
When 2 different atoms combined it will produced?
A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds.
What is it called when two substances dont mix?
The word “miscibility” describes how well two substances mix. Oil and water are said to be “immiscible,” because they do not mix. The oil layer is on top of the water because of the difference in density of the two liquids. The density of a substance is the ratio of its mass (weight) to its volume.
