I learned what covalent and ionice bonds are. I also learned what activation energy and what enzymes are and what they do in living systems.

I have learned about Ionic and Covalent bonds.
I have learned about pH scales and how to use them.
I have also learned how to draw atoms and to tell if they are stable or not.

3 Things I Learned From This Unit:

1)Enzymes are tailor-made catalysts.
2)Bases have more hydroxide ions, which are OH-.
3)Acids have more hydronium ions, which are H30+.

I learned about pH scales and how to use them..
I also learned how to draw atoms and how to find the # of neutrons in any atom..
I learned the 6 charcteristics of life

I've learned that an ionic bond has a bond of oppositely charged ions. An covalent bond shares the same electrons.Water is an example of an covalent bond. I also learned enyzmes are catalysts.

Over this unit I've learned about the pH scale and how there are 14 different levels. I also learned about the Table of Elements. I also learned about aqueous solutions.

I have learned about covalent and ionic bonds.
I learned more about the pH scale.
I also learned how to draw atoms based on their atomic number.

I learned about the two different bonds(ionic and covalent). I also learned about how protons, neutrons, and electron make up atom. I also learned how to use a pH table and how to tell the different atomic numbers on the periodic table.
