Create your own at Storyboard That PROTON 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. What are the atomic number and mass number of this atom? <_sodipodi3a_namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="4.9497475" inkscape:cx="72.731275" inkscape:cy="71.337534" inkscape:current-layer="layer1" inkscape:document-units="px" showgrid="true" inkscape:window-width="1920" inkscape:window-height="1060" inkscape:window-x="-8" inkscape:window-y="-4" inkscape:window-maximized="1"><_inkscape3a_grid type="xygrid" id="grid3812" empspacing="5" visible="true" enabled="true" snapvisiblegridlinesonly="true"> <_sodipodi3a_namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="4.9497475" inkscape:cx="72.731275" inkscape:cy="71.337534" inkscape:current-layer="layer1" inkscape:document-units="px" showgrid="true" inkscape:window-width="1920" inkscape:window-height="1060" inkscape:window-x="-8" inkscape:window-y="-4" inkscape:window-maximized="1"><_inkscape3a_grid type="xygrid" id="grid3812" empspacing="5" visible="true" enabled="true" snapvisiblegridlinesonly="true"> <_sodipodi3a_namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="4.9497475" inkscape:cx="72.731275" inkscape:cy="71.337534" inkscape:current-layer="layer1" inkscape:document-units="px" showgrid="true" inkscape:window-width="1920" inkscape:window-height="1060" inkscape:window-x="-8" inkscape:window-y="-4" inkscape:window-maximized="1"><_inkscape3a_grid type="xygrid" id="grid3812" empspacing="5" visible="true" enabled="true" snapvisiblegridlinesonly="true"> <_sodipodi3a_namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="4.9497475" inkscape:cx="72.731275" inkscape:cy="71.337534" inkscape:current-layer="layer1" inkscape:document-units="px" showgrid="true" inkscape:window-width="1920" inkscape:window-height="1060" inkscape:window-x="-8" inkscape:window-y="-4" inkscape:window-maximized="1"><_inkscape3a_grid type="xygrid" id="grid3812" empspacing="5" visible="true" enabled="true" snapvisiblegridlinesonly="true"> <_sodipodi3a_namedview id="base" pagecolor="#ffffff" bordercolor="#666666" borderopacity="1.0" inkscape:pageopacity="0.0" inkscape:pageshadow="2" inkscape:zoom="4.9497475" inkscape:cx="72.731275" inkscape:cy="71.337534" inkscape:current-layer="layer1" inkscape:document-units="px" showgrid="true" inkscape:window-width="1920" inkscape:window-height="1060" inkscape:window-x="-8" inkscape:window-y="-4" inkscape:window-maximized="1"><_inkscape3a_grid type="xygrid" id="grid3812" empspacing="5" visible="true" enabled="true" snapvisiblegridlinesonly="true"> The atomic number is 3.

Förstå Atomic Strukturer

Lektionsplaner av Amy Roediger

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.

Atom Diagram - Delar av en Atom

Storyboard Text

  • PROTON
  • NEUTRON
  • ELECTRON
  • The proton is found in the NUCLEUS of the atom. It has a relative charge of +1 and a relative mass of 1 amu.
  • ATOMIC NUMBER
  • The atomic number is 3.
  • The neutron is found in the NUCLEUS of the atom. It has a relative charge of 0 and a relative mass of 1 amu.
  • MASS NUMBER
  • The mass number is 7. 3 + 4 = 7
  • The electron is found outside the NUCLEUS of the atom. It has a relative charge of -1 and a relative mass of ~0 amu.
  • TRY IT!
  • 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.
  • What are the atomic number and mass number of this atom?
