- Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.
- The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
- Science Friday- This Fish Sucks
- Build An Atom PhET simulation- With a partner, use what you have learned about the structure of an atom to build an atom out of protons, neutrons, and electrons. Be sure that your atom is stable and neutral. What do you have to do to the atom to make it a positive charge? What do you have to do to make it a negative charge? Draw a sketch of your atom and explain where the protons, neutrons, and electrons are located. Explain why the atom was neutral and what you had to do to the atom to make it have a positive or negative charge.
Have an enjoyable, restful vacation and come back ready to learn more science!
