• All atoms are made of the same particles (protons, neutrons, electrons) in differing numbers
• what is an Atomic number

  The number of protons in the atom
• Mass number


  The number of protons and neutrons in the atom
• Isotopes


  Atoms with the same number of protons (atomic number) but a different number of neutrons (mass numbers)
• Neutrons have no charge and are also located in the nucleus of an atom.
• Protons are positively charged particles found in the nucleus of an atom.
• The nucleus is the central part of an atom, containing protons and neutrons.
• Isotopes are atoms with different numbers of neutrons but the same atomic number.
• Electrons have a negative charge and orbit around the nucleus of an atom.
• Protons have a positive charge and are located in the nucleus of an atom.
• An element is defined by its atomic number, which represents the number of protons in the nucleus of one atom of that element.
• The number of protons determines the element's identity (atomic number).
• Atomic mass is calculated by adding up the masses of all the neutrons and protons in an atom.
• Electrons are negatively charged particles orbiting around the nucleus of an atom.
• An element is defined by its atomic number which represents the number of protons in the nucleus of one atom of that element.
• An element is a substance made up of only one type of atom.
• A compound is formed when elements chemically bond together to form molecules or ionic compounds.
• A compound is a substance formed by combining two or more elements chemically.
• Atomic mass is calculated by adding up the masses of all the protons and neutrons in an atom.
