2.1 Atoms, Ions, and Molecules
Define atom, and identify its main parts and their features.
Key Concept: All living things are based on atoms and their interactions

2. How can this plant digest a frog?
If plants can make their own food through photosynthesis, hypothesize why would a plant species evolve a mechanism to capture and eat animals?

3. Please open to Pg. 35 and read the paragraph in white font for your answer…
Not EVERYTHING a plant needs is supplied by photosynthesis
Most plants absorb additional nutrients form the soil such as nitrogen and phosphorus
Venus fly traps live in swampy areas that have nitrogen poor soil, so they get this needed nitrogen by digesting animals

7. Fun Fact
It would take you over 1,000,000,000,000 (1 Trillion) years to count the number of atoms in a single grain of sand

8. Although there is a huge variety of matter on Earth, all atoms share the same basic structure…
Protons- in the nucleus, Positively charged (+)
Neutrons-in the nucleus, Neutrally charged (no charge)
Electrons-much smaller particles on the outside of the nucleus on the energy level, Negatively charged (-)
Energy Level

9. Energy levels: Electrons are located here
Energy levels: Electrons are located here. The inner level holds a maximum of 2 electrons.
Oxygen atom (O)
Nucleus: 8 protons (+) 8 neutrons
outermost energy level: 6 electrons (-)
inner energy level: 2 electrons (-)

11. What do you notice about these elements’ proton numbers and electron numbers?
Iron
Tin
50 P
50 E
69 N
79 P
79 E
118 N
Gold
Proton # =
Electron#
Aluminum
13 P
13 E
14 N

12. +P# = -E # = NEUTRAL!!!!! Gold electrically neutral!!!!
Atoms have equal numbers of +P and –E so they are...
electrically neutral!!!!
+79 + (-79) = ???
Gold
+79 + (-79) = 0
79 P
79 E
118 N
+P# = -E # = NEUTRAL!!!!!

13. An element is one or more atoms of the same type.
It cannot be broken down into simpler substances
Can be put together to make compounds or molecules
The atomic # (aka proton #) never varies
Ex: Only Gold has 79 protons, Only Hydrogen has 1 proton
gold
aluminum

14. Ex: Only Tin has 50 protons Only Aluminum has 13 protons Aluminum
Atoms of different elements differ in the number of protons they have. The proton # never varies.

15. How to read the Periodic Table of the Elements

16. How to read the Periodic Table of the Elements
Atomic # = Proton # = Electron #
All the same #!!!!!

17. How to read the Periodic Table of the Elements
Electron Configuration allows us to know how many electrons are in each energy level
6 energy levels
1st=2
2nd=8
3rd= 18
4th= 32
5th=18
6th= 1
= 79E

18. How to find the Proton, Electron, and Neutron # for any element
Atomic #
Element’s Symbol
Element Name
Atomic Mass
Number of Protons = Atomic #
Number of Electrons = #of Protons = Atomic #
Number of Neutrons = Mass # (rounded up) - Atomic # 79 79
=118

19. Create Your Own Atom (P#/E#/N#)
Mass (rounded up)-Atomic #= Neuron #

Sponge: Set up Cornell Notes on pg. 7 Topic: 2.1 Atoms, Ions, and Molecules Essential Question: How do ions form? Compare Ionic and Covalent bonding. Don’t forget to add it to your T.O.Contents!
2.1 Atoms, Ions, and Molecules
How do Ions form? Compare Ionic and covalent bonding.

22. Q: Because all atoms are made of the same types of particles (protons, neutrons, and electrons), what difference among atoms makes one element different from other elements?
Aluminum Iron Tin
A: Atoms of different elements differ in the number of protons they have.

23. A compound is made of 2 or more different elements bonded together in a certain ratio. Ex: H20
Carbon dioxide (CO2)
water (H2O) _ O H +
Draw mini picture

24. A molecule is two or more atoms held together by covalent bonds.
All compounds are molecules
NOT all molecules are compounds
covalent
covalent
Ex: O2
Hydrogen O O
Ex: H2O

25. Atoms Positive charge Proton # identifies element
Nucleus: most mass of atom
No electrical charge
Neutron
About same size as proton
Atom: smallest basic unit of matter
Is surrounded by
Negative charge
Electrons
# equals # of protons
Cloud: most volume of atom
Forms chemical bonds
Inner level only 2 Protons
Energy Levels
Other levels up to 8 Protons
Tries to fill outer level

26. An ion is an atom that has gained or lost one or more electrons (-)
An ion is an atom that has gained or lost one or more electrons (-). An ion forms because an atom is more stable when its outermost energy level is full. - +

27. Mostly empty outer energy levels= lose those electrons -
Positive Ions:
Mostly empty outer energy levels= lose those electrons
Become POSITIVELY charged ion
Negative Ions:
Nearly full outer energy level =gain electrons
Become a NEGATIVELY charged ion
Energy level

30. + - Please draw and Label on the top 1/3 of pg. 6 IONS 11P 17P 11P (+)

32. Understanding how an ion forms ionic bonds and covalent bonds is important because ions play large roles in organisms.
They are important in all biological processes. A few examples are:
They play a role in muscle contraction and cell shape
Chloride (Cl-) is a chemical the human body needs for metabolism (the process of turning food into energy)
Calcium ions (Ca2+) are necessary for every muscle movement in your body

33. Ionic bonds form between oppositely charged ions. Dissolve in H2O.
Draw in the middle section of pg. 6
“Opposites Attract!!!!”
Now we have salt!!!!

34. H2O covalent bonds Share electrons in outer energy level
Can have multiple bonds
