The date's a little screwy because we had a snow day.
Today in class we started talking about valence electrons and the types of bonds atoms form. It's important that we know and understanding molecular bonding, because that affects a lot or our bodily processes and will great increase our understanding of cellular actions.
The key to understanding bonds is valence electrons. Remember, valence electrons are the outer most electrons in the outside shell. The group (column) on the periodic table tells you how many valence electrons an element will have. this will in turn tell you what type of ion it'll form when we're talking about ionic bonds.
Covalent bonds a different because instead of an electron being transferred, the electrons are shared with amongst the atoms.
Download that powerpoint notes here: ICB Atoms, Valenece Electrons and Bonding.
You can download the second note sheet here if you weren't in class: Second Note Sheet for Atoms
We're going to dive (no pun intended) into water chemistry to really understand the cells and how they work.
Until next time, have a great Thanksgiving.
