Warm-up: 10/12---Thursday
When the bell rings… Be quiet and ready for class. Read the new objectives and essential questions. Make sure your word wall example is pass up to the front of your row, you have a pen/pencil, and the notes.
2
Reminders for today… Sign out a computer and log on
Before you start anything make a plan for what you are going to accomplish today… Go to my website and use the websites provided (first period you may use other sources in order to complete your project. Remember to cite your sources and be sure to consider quality and neatness when creating your products.
3
Warm-up from Bill Nye video…
What is an atom? What are the three main parts of an atom. How do the particles of an atom differ in electrical charge?
4
An atom is the smallest particle an element can be divided into and still be that element. The 3 parts are proton (positive charge+). Neutron (no charge 0), and electron (negative charge -)
5
Warm-up List how many protons and electrons the following elements have: Hydrogen, Sodium, Iron, and Krypton
6
In what ways are atoms of Oxygen different than atoms of Carbon?
Warm-up In what ways are atoms of Oxygen different than atoms of Carbon? Take the candy atoms sheet off of front table and read it.
7
Warm-up Take a periodic table from the front table, choose 3 colored pencils and create a color coded key for solids, liquids (only 2 on the table), and gases.
8
Draw the atomic structure of an element from the periodic table.
Warm-up Draw the atomic structure of an element from the periodic table. Label the nucleus, protons, neutrons, electrons and charges.
9
Construct an analogy: Element:Compound as _____: _____
Warm-up Construct an analogy: Element:Compound as _____: _____ Atom:Element as ________: _______ Take the candy atom instructions from the front table. On the back of your sheet draw the atomic structure of an atom of your choice with an atomic # between 2-10. I must approve your drawing before you can get materials to build your 3-D model.
10
The Atom and the periodic table
11
Objectives Describe and define atoms.
Recognize that all matter is made up of atoms and atoms of the same element are all alike, but are different from the atoms of other elements. Describe the relationship between numbers of protons and atomic number on the periodic table.
12
What is the relationship between atoms and elements?
ESSENTIAL QUESTIONs What is the relationship between atoms and elements? How are atoms of one element similar to and different from atoms of other elements?
13
What is the relationship between atoms and elements?
Warm-up Can you answer the essential questions… What is the relationship between atoms and elements? How are atoms of one element similar to and different from atoms of other elements?
14
What is a pure substance? Is a substance in which there is a
uniform composition of “particles”. The particles we are talking about are atoms. What is a pure substance?
17
A substance that contains only one type of atom
A substance that contains only one type of atom. All known elements are organized on the periodic table of elements. What is an element? meet the elements song
18
What is a compound? Is a combination of elements that come together through a chemical reaction and becomes something called a molecule. A molecule is two or more different elements combined in a specific ratio.
19
The smallest part of an element that has the same properties of that element. In Greek, means “uncuttable”. What is an atom? atom video w animation
22
What is an atom? Atom cont…
These particles are too small to be seen with a microscope. Atoms have all the properties of matter: mass and volume
23
Superman Study Jams atoms
25
+ What Is an atom Protons – Made
of? Atoms on discovery ed. Protons – Found in the atom’s nucleus and has a positive charge. Protons + protons
26
What 2 things are found inside the nucleus?
What Is an atom Made of? Neutrons – Found in the atom’s nucleus and has no charge. The nucleus contains most of the atom’s mass n Neutrons What 2 things are found inside the nucleus? Neutrons Protons
27
- What Is an atom Made of? Electrons –
Found circling the atom’s nucleus. - Each has a negative charge. Electron Electrons
28
Label Me! 1. 3. 2. 4.
29
What is the atomic number? The atomic number is the number of
protons in the nucleus of that atom. All atoms of the same element have the same atomic number. What is the atomic number?
30
Here is an example of one of the elements on the periodic table.
atomic number - # of protons in the nucleus. 3 Li Lithium 6.94 element symbol element name atomic mass –mass of the protons and neutrons
31
What is the Atomic Number?
32
Mass # Isotopes
34
How do Atoms of Different Elements Differ?
Starting Simply The hydrogen atom has one proton and one electron. Now for Some Neutrons The helium atom has two protons, two neutrons, and two electrons. Building Bigger Atoms For bigger atoms, simply add protons, neutrons, and electrons. Protons and Atomic Number The number of protons in the nucleus of an atom is the atomic number of that atom. All atoms of an element have the same atomic number.
35
Describe and define atoms. Name the parts of an atom.
Objectives review Describe and define atoms. Name the parts of an atom. Describe the relationship between numbers of protons and atomic number on the periodic table.
36
How is matter alike or different on the molecular level?
ESSENTIAL QUESTIONs How is matter alike or different on the molecular level? How is the # of Protons related to the atomic # on the periodic table?
