elements
Elements are substances made of identical atoms which cannot be broken down to other substances. Matter is anything that occupies space and has mass.
Elements and compounds (pure substances) cannot be broken down by physical changes.
Two substances that cannot be broken down by chemical change are elements and compounds. Elements are fundamental building blocks of matter that cannot be broken down into simpler substances by chemical reactions. Compounds are made up of two or more different elements chemically bonded together in fixed ratios, and they also cannot be broken down into simpler substances by chemical reactions.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
Substances that cannot be chemically broken down into simpler substances are called elements.
Elements.
All substances can be broken into any other substances (or elements) by chemical or physical methods.
Those substances are called elements. Elements are pure substances made up of only one type of atom and cannot be further broken down or decomposed into simpler substances by chemical reactions.
That would be an Element.
This is called an element.
Elements are substances made of identical atoms which cannot be broken down to other substances. Matter is anything that occupies space and has mass.
An element is a pure substance that cannot be broken down into simpler substances by chemical means.
No: Compounds are simple mixtures of substances
That is a fairly good definition for an "Element".
elements.
The atom cannot be broken by chemical methods.
