WHAT ARE ELEMENTS?
Elements are pure substances made of only one type of atom. An atom is made of protons, neutrons, and electrons. For example, a carbon atom has 6 protons, 6 neutrons, and 6 electrons. This gives carbon unique properties that can be used to identify it. There are 118 naturally occurring elements, each one has a different number of protons.

LET’S BREAK IT DOWN!
Elements are made of the same types of atoms.
Elements are naturally occurring substances that exist in all three states—solid, liquid, and gas. Elements are made of the same types of atoms. For example, oxygen exists naturally as a diatomic element, meaning that it has two oxygen atoms. Each atom is made of protons, neutrons, and electrons. Protons and neutrons are positioned in the center of the atom called the nucleus, and electrons are found in the outer portions of the atom called energy levels, or electron orbitals.

All elements have properties.
All elements have properties. Those properties include, but are not limited to, conductivity, magnetism, melting point, boiling point, color, state of matter, and others. Elements with similar properties are grouped together in different areas of the periodic table of elements. Observing an element’s properties allows scientists to categorize it and also determine its reactivity with other elements. Where the element is positioned on the periodic table will determine how it combines, or doesn’t, with other elements.
