Name: Nelda Neutron

Description:Neutral

Favorite Activity:Hanging out at the Nucleus Arcade

In the center of Matterville, there is a place called the Nucleus Arcade, where two members of the Atoms Family like to hang out. Perky Patty Proton, like her sisters, is quite large with a huge smile and eyes that sparkle (+). Patty is always happy and has a very positive personality. Nerdy Nelda Neutron is large like Patty, but she has a boring, flat mouth and eyes with zero expression (o). Patty, Nelda, and their sisters spend all their time at the arcade.

The Atoms Family from Matterville

Name: Patty Proton

Description:Positive

Favorite Activity:Hanging out at the Nucleus Arcade

Name: Elliott Electron

Description:Negative

Favorite Activity:Racing around the arcade

Around the Nucleus Arcade, you will find a series of roadways that are used by the brothers in the Atoms Family. Elliott Electron races madly around the Arcade on his go-kart. Elliott is much smaller than Patty and Nelda and he is always angry because his big sisters will not let him into the Arcade. He has a frown on his face, eyes that are squinted with anger, and a very negative (-) attitude. Elliot and his brothers are forced to hang out on the streets outside the arcade.

PART 1:MATTERVILLE IS NEUTRAL AS LONG AS EVERY

ATOM HAS THE SAME NUMBER OF PROTONS (+) AND ELECTRONS (-) TO MAINTAIN A BALANCED

CHARGE!

BUT WHAT HAPPENS WHEN THEY DON’T…?

Changing the # of Protons = Different

ElementThe number of protons determines The number of protons determines what element it is – what element it is – like an ID #like an ID #

SO…changing the number of SO…changing the number of protons results in a different protons results in a different element!element!

It could make the element It could make the element unstable or radioactive!unstable or radioactive!

Changing the # of Changing the # of Electrons = Electrons = IonsIons

IonsIons are atoms that have a charge are atoms that have a charge

Ions form when an atom gains or loses Ions form when an atom gains or loses electronselectrons

Gain an electron = negative charge = Gain an electron = negative charge = anionanion

Lose an electron = positive charge = Lose an electron = positive charge = cationcation

Why would an atom want to gain or lose Why would an atom want to gain or lose electrons…hmmm?electrons…hmmm?

Matterville is neutral as long as each negative Electron brother is balanced out by one positive Proton sister.

Challenge: What would happen in Matterville if one Electron brother was kidnapped?

Challenge 2: What would happen in Matterville if Electron Eddie, a cousin, moved to Matterville?

Changing the # of Neutrons = Isotopes

IsotopesIsotopes are atoms of the same are atoms of the same element that have a different element that have a different number of neutrons.number of neutrons.

Adding or losing a neutron is like Adding or losing a neutron is like gaining or losing weight…same gaining or losing weight…same identity, different mass!identity, different mass!

(Remember, neutrons have NO (Remember, neutrons have NO charge, but they are large like charge, but they are large like protons, so when you gain or lose protons, so when you gain or lose them it ONLY affects the mass!) them it ONLY affects the mass!)

Practicing Atomic Practicing Atomic ChangesChanges

……CONTINUEDCONTINUED

REMEMBER: The Electrons are only allowed on the streets around the arcade. The first “street” can only hold 2 Electron brothers. The second “street,” can hold 8 brothers. The third “street,” can hold an additional 8 brothers.

Nucleus ArcadeContains protons & neutrons

2nd “street” can hold 8 electrons

3rd “street” can hold 8 electrons

1st “street” can only hold 2 electrons

The outermost shell or “street” is called the valence shell. The electrons on that shell are called valence electrons. The atom wants it’s valence shell to be full so that it is stable and happy.

2nd “street” can hold 8 electrons

3rd “street” can hold 8 electrons

1st “street” can only hold 2 electrons

PART 2: MATTERVILLE IS STABLE AS LONG AS ALL OF

THE VALENCE SHELLS ARE FULL!

BUT HOW DO WE KNOW IF THEY ARE FULL?

We Need to Learn to We Need to Learn to Draw an Atom for Each Draw an Atom for Each

SHELL IF YOU NEED IT!SHELL IF YOU NEED IT!

Step 1: Draw the Nucleus

Step 2: Draw the 1st shell and fill it

Step 3: Draw the 2nd shell and fill it

Step 4: Draw the 3rd shell etc. until all of the electrons for that specific element are on a shell
