Definition Of Atom Element Compound Molecule

Not all molecules are compounds because some molecules such as hydrogen gas or ozone consist only of one element of only one type of atom. An element is a substance that cannot be broken down further by chemical means.

And a compound is a type of molecule in which the types of atoms forming the molecule are different from each other.

Definition of atom element compound molecule. A compound consists of atoms of two or more different elements bound together. The elements in a compound do not always retain their. A molecule is a substance that contains two or more atoms chemically joined such as H_2 O_2 A compound is a substance that is made up of two or more different elements that are chemically joined such as H_2O CO NaCl.

Two or more atoms or elements combined together are called a molecule. A compound consists of two or more types of elements held together by covalent or ionic bonds. Molecules of elements The molecule of an element contains two or more similar atoms chemically combined together.

Chemical bonds link elements together to form more complex molecules called compounds. Each atom type contains the same number of protons. A molecule of hydrogen element contains 2 hydrogen atoms combined together and it is written as H 2.

Compounds are composed of different elements in a fixed proportion. For example water is. All compounds are molecules but all molecules are not compound.

A substance that is made up of two or more separate elements chemically joint together mixture A substance made by mixing other substances together which are not chemically joint together. An element is a substance that is made entirely of one type of atom. For example 1 atom of sodium Na combines with 1 atom of chlorine Cl to form one molecule of sodium chloride NaCl compound.

A molecule is a group of two or more atoms held together by chemical bonds. Therefore a compound is also a type of molecule but they are not the same. For example the element sodium is made up of only sodium atoms.

A moleculeconsists of two or more atoms of the same element or different elements that are chemically bound together. Molecules of compounds The molecule of a compound contains two or more different types of atoms chemically combined together. There are over 100 different elements which are made up of atoms.

Any substance that contains only one kind of an atom is known as an element. A compound is a substance that is composed from two or more different elements. An element is a material that consists of a single type of atom.

Water H 2 O table salt NaCl carbon dioxide CO 2 methane CH 4 etc. A compound is a substance that contains atoms of two or more different elements and these atoms are chemically joined together. H 2 NaCl N 2 etc.

Can be broken down into a simpler type of matter elements by chemical means but not. Because atoms cannot be created or destroyed in a chemical reaction elements such as phosphorus P4 or sulfur S8 cannot be broken down into simpler substances by these reactions. Chemical symbols and formulae are used to represent elements and compounds.

Note that the two nitrogen atoms which comprise a nitrogen molecule move as a unit. Elements can be divided into metals and non-metals. A molecule is a substance that is made out of two or more atoms bonded via chemical bonds.

A compound is a molecule composed of different types of atoms bonded via chemical bonds. Water decomposes into a mixture. A molecule is formed when two or more atoms of an element chemically join together.
