Atoms and Ions and Bonds.......Oh MY!!

Our nucleus prop
Not MUCH hapening - just a bunch
of protons and neutrons hanging out!!

Daily Questions  Wednesday September 5^th

The nucleus of an atom contains which subatomic particles? Protons and Neutrons

Of these two – which defines an element? Protons(remember - that is really the only real "EXCITING thing" about the proton is that it defines the element.  Not much going on - I related it to the "couch potato" of the atom.

Watch out - you slack off in here and
an electron may come flying your way.
 

Gold has the atomic number 79.  How many protons are in an atom of gold?  How many electrons are there?

 79 Protons and 79 Electrons (Remember - in an elecrtically neutral atom, the number of protons = the number of electrons)

Which part of an atom is important in bonding and determining the charge of an atom?

 Electrons "The MUCH more exciting and 'electric' part of the atom!!"
 

An atom that has a charge is known as an Ion

How was this charge acquired?  By the gaining or losing of Electrons

Today we continued through the notes on ions and in to bonding.  I told you I would never make you learn something that I couldn't give you a reason WHY you should know it.  That is why after the discussion on ions I played the following pod cast on electrolytes.  We will continue to see how this all plays a role in "life" as the chapter goes on!

Keep holding on to those papers I gave you yesterday, we will be working through the content of them over the next couple days and I will let you know when they are due soon! 

Way to work in the heat guys :)
