It has a relative charge of +1 and a relative mass of 1 amu. The neutron is found in the NUCLEUS of the atom. It has a relative charge of 0 and a relative mass of 1 amu. The electron is found outside the NUCLEUS of the atom. It has a relative charge of -1 and a relative mass of ~0 amu. The atomic number tells us the number of PROTONS in an atom. Since atoms have no charge, it also tells us the number of ELECTRONS in an atom. The mass number is the sum of PROTONS + NEUTRONS in the atom. Since protons and neutrons each have a mass of 1 amu, their sum is the same as the mass.

Create your own at Storyboard ThatPROTON NEUTRON ELECTRON ATOMIC NUMBER MASS NUMBER TRY IT! The proton is found in the NUCLEUS of the atom. It has a relative charge of +1 and a relative mass of 1 amu. The neutron is found in the NUCLEUS of the atom. It has a relative charge of 0 and a relative mass of 1 amu. The electron is found outside the NUCLEUS of the atom. It has a relative charge of -1 and a relative mass of ~0 amu. The atomic number tells us the number of PROTONS in an atom. Since atoms have no charge, it also tells us the number of ELECTRONS in an atom. The mass number is the sum of PROTONS + NEUTRONS in the atom. Since protons and neutrons each have a mass of 1 amu, their sum is the same as the mass.

Naturvetenskapslärare förlitar sig ofta på analogier och jämförelser för att hjälpa eleverna att föreställa sig hur en atom "ser ut". Följande aktiviteter syftar till att hjälpa eleverna att förstå atomen, eftersom den fungerar som grunden för resten av kemin och spelar en viktig roll i många delar av fysiken.
