If all atoms in a substance are alike, the substance is called an element. Elements are pure substances that cannot be broken down into simpler substances by chemical means and are defined by the number of protons in their atomic nuclei. Each element has unique properties and is represented on the Periodic Table.

neutrons of all atoms are alike
pure substance
A substance where the actual number of atoms is not significant, as long as they are all of the same element, is called a chemical compound. This is because the properties of compounds are determined by the arrangement and types of atoms within the molecules, rather than their quantity.
A substance in which all the atoms are the same is called an "element".
A substance in which all atoms are identical is called an element.
A substance in which all atoms are alike is an element.
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.

True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
neutrons of all atoms are alike
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is called a molecule. Each molecule is made up of one or more atoms chemically bonded together.
An element. The particules are atoms.
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.

The total kinetic energy of a substance's atoms is the sum of the kinetic energies of all the individual atoms in the substance. It is a measure of the overall motion of the atoms within the substance.
