My Answer: The point of this demonstration was to…
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------There are various tabs (Engage, Explore, Explain, Elaborate, Evaluate) that you will be clicking through during this unit. Each tab has quite a few
videos, articles, activities, and more. You are not required to view every video or read every article, but the more you information that you browse,
the more complete your understanding may be which will help in answering the Essential Questions
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The Essential Questions
These questions shouldn’t be a one sentence answer. You may have to watch several videos to be able answer them fully. The point of putting
them up here at the front is to make sure that they stay at the fore-front of your mind. If you feel like you gain valuable information from one of the
videos, scroll down and add some of that to the question at the bottom of this document. That way you build these answers up with information
from multiple sources as you go.
1. What is the relationship between an atom and an element?
2. How are protons and neutrons different from and similar to each other?
3. How do electrons differ from both protons and neutrons?
4. How are protons, neutrons, and electrons arranged to form an atom?
5. What are two ways electrons can be gained or lost from an atom?

The Basic Identity of an Element
1.
In this Gizmo, subatomic particles can be added to an atom or removed from it by clicking the arrows
next to each supply of particles. Remove any protons, neutrons, or electrons that are currently in the
atom by clicking the left arrows.
What is the area where the electrons are located called?
What is the area where the protons and neutrons located called?
a.
Using the right arrows, add 1 proton, 2 neutrons, and 2 electrons to the atom so that there are 2 of
each of the three particles located in the atom. Fill in Table #1.

2. Place a check in the “Show element name” box, which is in the top right portion of the gizmo. Manipulate
the number of protons to achieve the number of protons in Table #2. Do not worry about the number of
neutrons or electrons. Experiment with adding one and removing one proton to and from the atom. Fill in
the following table. Once you have the identity of the element, look at the periodic table and write down
the atomic number for the element, this is the integer located above the name of the element.
a. Does changing the number of protons change the identity of the element you have built?
b. What is the relationship between the number of protons and the atomic number for an element?
3. For Table #3 you will do the same thing as step 2 except you will be changing the number of neutrons. For
Table #4 you will do the same thing as step 2 except you will be changing the number of electrons. Make
sure that you begin with 2 each for the protons, neutrons, and electrons.

a. Does changing the number of neutrons / electrons change the identity of the element you have
built?
b. Does changing the number of neutrons / electrons change the affect the atomic number?
Key Fact: What is the key determinant of the type of atom?
Mass of an atom
1. Build an atom again with exactly 2 protons, 2 neutrons, and 2 electrons. Check “Show element symbol.” Be
sure “isotope” is not selected. Make adjustments to the atom to attain the number of protons, neutrons,
and electrons as shown in the data table. Then finish filling in the table. The number to the upper left of
the symbol indicates the mass of the atom. (See where the pointer is pointing in the screen shot.)

5. Which 2 subatomic particles affect the mass of an atom?
SUMMARY: Based on this gizmo, the number of protons equals the _______________ ______________ from
the periodic table. The number of protons determines the _______________ of an atom. The ____________
and _______________ determines the mass of an atom. The protons and neutrons are located in the
________________ of an atom and electrons are in the ________________ ______________.
How many protons are in the nucleus of an atom of Carbon (C)?
What is the formula for finding the mass number of an atom?
If an atom of C has 7 neutrons in the nucleus, then it would have a mass number of ______. (see previous 2
questions)
How many electrons would be found in the nucleus?

Part Three –
The Element Project (2 days)
Using the basic common elements list, you need to come up and choose one element to do some research on.
Only one student is able to do each element, so the selection is based on a first come, first serve basis. Tell the teacher
which element you would like to research and then find out some basic information on that element. You will create 2
slides that give some of the information about your element that you will present to the class in the end.
Possible Resources to Use:
The Discovery Techbook: The Interactive Periodic Table, Elaborate Tab
www.chemicool.com
www.webelements.com
http://www.chemeddl.org/resources/ptl/index.php
Information that needs to be in your slides.
Element Name:
Atomic Number:
Atomic Mass:
Number of Protons:
Number of Neutrons:
Number of Electrons:
Number of Valence Electrons
Most Common Isotope:
3 Main Uses of the Element:
2 Interesting Facts about your Element:
3-4 pictures of your element, or various compounds that your element is a part of.
In time, you will get me a copy of your slides, we will add them to the major presentation and then you will need
to present your slides in front of the class. When you present it is very important that you do not just stand there and
read your slides. If you do I will snore loudly and you will not do well on the presentation component of your grade.
Your slides need to organize the information and not be overwhelming.
Bonus points will be given to students who can create a short story, or poem, or comic strip about their element
and it’s uses. The amount of bonus depends on the quality of work. The bonus points will not exceed 8 points.
