Assemble or draw Bohr atomic models for the first 18 elements and group them according to
the number of outer shell electrons.
Recall that Bohr put the ELECTRONS into ORBITALS which are like CIRCLES
around the NUCLEUS.
Each ORBIT (SH
Compounds, Elements, and Molecules
Compare elements to compounds. Include: atoms, molecules
We must be able to differentiate between the following terms:
- Smallest UNIT of an ELEMENT.
- Made of PROTONS, ELECTRONS and NEUTRONS
Explain the atomic structure of an atom in terms of the number of protons, electrons, and
neutrons, and explain how those numbers define atomic number and atomic mass.
Most bikes are made of Aluminum and not Gold. Why?
