Expert-Verified Answer

Elements are those substances that are composed of one kind of atom. They cannot be broken down into simpler types of matter by either physical or chemical means.

/ ĕl′ə-mənt / A substance that cannot be broken down into simpler substances by chemical means. An element is composed of atoms that have the same atomic number, that is, each atom has the same number of protons in its nucleus as all other atoms of that element.

DECOMPOSITION – reaction where one substance breaks down, or decomposes, into two or more simpler substances.

Compounds can be broken down into simpler substances using various chemical reactions. Compounds are composed of different elements combined in a chemical reaction. Therefore, if we break down a compound, the individual elements will dissociate and exist alone.

An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.

An element is a substance that cannot be chemically interconverted or broken down into simpler substances.

(EH-leh-ment) A basic part of a whole. In chemistry, refers to a simple substance that cannot be broken down into smaller parts or changed into another substance. The basic part of an element is an atom, which contains protons, neutrons, and electrons. All atoms of an element have the same number of protons.

An element is a substance that cannot be broken down into any other substance. There are about 100 elements, each with its own type of atom. We often think of atoms as tiny spheres, but in fact they are made from smaller particles called protons, neutrons and electrons..

Explanation: A decomposition reaction is a reaction where complex compounds or molecules are broken down into simpler molecules.

What is a reaction involving substances broken down from simpler substances called? ›

Hence, a reaction in which a substance breaks up into two or more simpler substances is known as a decomposition reaction.

Decomposition is a chemical process wherein a compound breaks down into simpler substances.

An element is a substance whose atoms all have the same number of protons: another way of saying this is that all atoms of a given element have the same number of protons. Elements are the simplest chemical forms and thus can not be broken down through chemical reactions.

Compounds are the chemical substances which can be further subdivided into simpler substances through chemical methods only. This is due to the fact that compounds are made up of chemical combination of elements, thus they can be separated by only chemical means.

According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds.

A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen. Today, there are about 118 elements in the known universe.

Compounds can be separated into simpler substances through various processes. One common method is decomposition, where heat or other chemical reactions are used to break down the compound into its constituent elements. For example, when heating water (H₂O), it decomposes into hydrogen gas (H₂) and oxygen gas (O₂).

Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Binary compounds are compounds composed of just two elements. The simplest kind of decomposition reaction is when a binary compound decomposes into its elements.

Nuclear transmutation is the conversion of one chemical element or isotope into another. In other words, atoms of one element can be changed into atoms of another element by transmutation.
