Directions: Watch the videos on atomic structures.
EXPLORE : Answer the following questions in your notebook; Search the web if needed:
1. How many electrons does a carbon atom have?
2. How many protons does a carbon atom have?
3. What is a valence electron?
4. What is an isotope? Use the web if needed.
5. What is the center of an atom called?
EXPLAIN : Read this Slide presentation. You may refer back to it. ATOMS
EXTEND: 1. Draw a model of an oxygen atom.
Show the number of electrons in the correct orbitals, the number of neutrons and the number of protons. protons = 8, electrons = 8 and neutrons = 8 (Hint : there are 2 e- in the first orbital, 6 e- in the second orbital )
2. Draw a model for a Carbon atom.
EVALUATE : Answer the Questions on this Google Form as a practice Quiz :
Beyond : Go to the next level...1. Try drawing a model showing two atoms of hydrogen bonding with one atom of oxygen in a water molecule. Show all of the electrons, neutrons and protons.
2. Draw a model of a carbon dioxide molecule , showing the electrons, protons and neutrons.
