Question description



Webquest: Dividing the Indivisible

From 1803 to 1897, scientists continued to discover new elements and explain the behavior of matter in terms of the fundamental, indivisible particles. Like Democritus, Dalton and other scientists of his day agreed that these solid bits of matter could not be divided or cut into any smaller, more fundamental particles. Why should they believe otherwise?Treating atoms as solid bits of matter allowed them to explain a wide range of properties and behaviors of matter.

This understanding changed dramatically in 1897 with the discovery of the first subatomic particle. Complete theWebquest to discover the subatomic particles that were discovered between 1897 and 1932, the stories of how they were discovered, and the names and backgrounds of the people who discovered them.

4.01 web quest 

WebQuest: Get To Know the Neighborhood

What do you do when you move into a new neighborhood? You walk around, meet the people on your street, and locate the parks, the movie theaters and other places of interest. In this WebQuest, you will get to know the periodic table and the elements it organizes. You’ll discover:

  • Which elements make up the human body?
  • Are these the same elements that are abundant in Earth’s crust?
  • How are elements on the right side of the periodic table similar to and different from elements on the left side?
  • Is there a pattern to these characteristics?
  • Are Internet periodic tables the same as ones printed on paper?

Download the WebQuest worksheet and use it to record the information you discover. Submit your completed worksheet to the WebQuest: Get to Know the Neighborhood assignment link for grading. For more information on how this will be graded, please view the WebQuest: Get to Know the Neighborhood rubric.

4.02 
WebQuest: Origins of Element Names

Often, when an element symbol doesn’t seem to match its name, the symbol may refer to an older element name that is not used any more. Or the symbol may stand for a word that is not in the English language. Remember, the 118 known chemical elements have been discovered by a variety of people in a range of countries over thousands of years. The wide range of chemical names gives clues to this diversity.

If you discovered a new element, how would you name it? Would you name it after yourself or for the place where the element was found? Would you name it to describe the way the element looked? Maybe you would want to honor a friend, mentor or mythological god by naming the element after that person.

Complete the following WebQuest to discover the origins of several chemical element names. Submit your completed assignment to the WebQuest: Origins of Element Names assignment link for grading. For more information on how this assignment will be graded, please view the WebQuest: Origins of Element Names rubric.

4.04

Project: Ions for your Health

The ions found in sports drinks are not chosen randomly; they are the same ones that are lost from your body when you exercise vigorously. A wide range of ions play critical roles in maintaining health and proper body function. Some of these ions are present in the body in relatively large amounts and some are present only in trace amounts. Other ions can be toxic to humans, even in small amounts.

Follow the directions outlined in the project guide. For this assignment, you will report your findings in a podcast, script, or brochure that includes all the pertinent information. Be creative in your reporting—use this opportunity to "advertise" the importance of these ions to human health.

Submit your completed project to the Project: Ions for Your Health assignment link for grading. For more information on how this assignment will be graded, please view the grading rubric.

4.01
A heavy metal refers to a relatively metal
1. A super heavy element refers to elements with their atomic numbers greater than 112
2. Some elements are basically discovered by accident while others are discovered after a
thorough research into a given mineral or compound. In other instances, certain elements
can be predicted for existence on the basis of the Periodic table.
3.


Are mostly produced in small quantities that is one atom at a time



Their identification is usually difficult as most half-lives range from
minutes to milliseconds.



Members of these groups have short-lived life-cycles in the radioactivity
series.



The synthesis of these elements becomes accomplished through fusion of
the nuclei of lighter elements.

4. An island of stability refers to the set of predicted though yet undiscovered isotopes that
are usually heavy and believed to be much stable than those closer in atomic numbers of
uranium. Sea of stability refers to a region of the elements in the periodic table whereby
the elements are highly unstable. They exhibit shorter half-lives measurable in micro or
nanoseconds
5. This type of research becomes very important especially in discovery of new elements
and also

finding more explanations to the various behaviors of elements.

6. The elements find a practical use in the manufacture of building materials

4.02

Calcium

How, who and when the element was

The story behind the element’s name and

discovered

the chemical symbol

Calcium was first discovered by

The chemical symbol in Calcium, Ca

Humphrey Davy in 1808 as a metal

was derived from latin calx for the ‘lime’

base in the chemical substance Latin

in which its origin was was found.

calx meant for lime. The basic
substance in limestone that became
part of the element.
Sodium
