Atoms: The Building Blocks of Everything
Atoms are the basic building blocks of matter. They are made up of a nucleus, protons, neutrons, and electrons. Atoms of different elements have different properties. For example, oxygen atoms are reactive and combine with other elements to form molecules. Atoms can combine to form molecules, which are the basis of all life on Earth. They are also essential for the formation of materials like metals, plastics, and glass.
Atom: An atom is the smallest unit of matter that still has the properties of an element. All matter is made up of atoms.
Molecule: Molecules are combinations of atoms that are held together by chemical bonds. They are the smallest unit of a compound.
Periodic Table: The periodic table is a chart that organizes all of the known elements into groups and rows based on their chemical and physical properties.
What do you think are the most important properties of atoms?
Did you know?
Atoms are 99.9999999999% empty space. The nucleus of an atom is only about 100,000 times smaller than the atom itself. The electron cloud of an atom is so small that it can only be seen using an electron microscope. If an atom was the size of a football field, the nucleus would be the size of a pea.
