Document Summary

Without knowing how the code is written, test whether the code functions as expected. Knowing how the code is written, test all of the possible paths through the program are tested. Both the true path and the false path of an if statement are tested. Cases that are on the transition between behaviours (at the extreme). E. g. if division by 4, would need to try inputs less than 4 equal to 4 and greater than 4. This is the testing of those larger groups of data, which can be represented by many numbers. Testing a positive number, a negative number, a decimal, etc. Area mechanism for grouping data continuously. (arrays) Vectors are created using square brackets [ ] Elements are separated by commas (or a space) , Elements are accessed using round brackets ( ) with an element index number inside. A vector is a 1-dimensional data structure. E. g. as elements are added it grows in one direction.

MODERN PERIODIC TABLE

The periodic table is a tabular arrangement of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties.

Elements are presented in order of increasing atomic number (the number of protons in the nucleus). The standard form of the table consists of a grid of elements laid out in 18 columns and 7 rows, with a double row of elements below that. (Please see periodic table provided above.)

The horizontal rows of the table are called periods and the vertical columns are called groups. The periodic table incorporates recurring trends and can therefore be used to derive relationships between the properties of the elements and predict the properties of new, yet to be discovered or synthesized, elements. As a result, a periodic table provides a useful framework for analyzing chemical behavior.

Main group (or representative) elements include elements (except hydrogen) in groups 1 and 2 and groups 13 to 18. In older nomenclature, the main group elements are groups lA and lIA, and groups IIIB to O (CAS groups IIIA to VIIIA).

The elements in groups 3 to 12 are the transition elements, the focus of this exercise.

Transition elements are divided into two groups:

the transition metals

the inner transition metals

The two sets of inner transition metals are located along the bottom of the periodic table and are known as the lanthanide series and the actinide series. (See periodic table provided above.) The rest of the elements in groups 3 to 12 are transition metals.

Transactinide elements (also called transactinides, or super-heavy elements) are the elements with atomic numbers greater than those of the actinides. (The heaviest actinide is lawrencium (103).)

Transuranium (or transuranic) elements are those elements having an atomic number greater than that of uranium (92), an actinide. (Thus all transactinide elements are also transuranium elements.)

Transuranium elements are unstable and decay radioactively into other elements.

These elements were all first discovered in the laboratory, with neptunium, plutonium, americium, curium, berkelium, and californium later also discovered in nature.

Transuranium elements can be synthesized in the laboratory through the use of nuclear reactors or particle accelerators.

Please review the following questions:

1. Are all transactinide elements transuranium elements?

2. Are all tranuranium elements actinides?

3. List two unique properties of transuranium elements:

A.

B.

For the following symbols, provide the element name and indicate whether it is a representative element, a lanthanide, an actinide, or a transactinide element.

4. Cf

5. Pm

6. Ag

In this assignment you will be using the scientific method to develop your own experiment. You will not be conducting the experiment but you will develop one based on a hypothesis. You will submit a project containing the needed information outlined under the "Project" section.

Background Information:

The scientific method is a process used by scientists to develop experiments and test hypotheses. This process begins by making observations. The next step is to develop a question based on these observations, such as how something works.

Based on the question under investigation, a hypothesis is created. A hypothesis should be a prediction of what happens. It is written in an "if, then" format. An is designed to test a specific hypothesis. A scientific experiment should have an independent variable, dependent variable, and a control group. The independent experiment variable is what is changed in the experiment. The dependent variable is what is measured in the experiment.

A control group is a group in which the independent variable undergoes no change. The control group in an experiment serves as a baseline to measure the results of the experiment and can be very useful in isolating unknown factors which may influence the dependent variable.

Remember that a good experiment includes multiple repetitions for each experimental group.

Once an experiment has been conducted, all of the data collected is analyzed. Scientists look for trends in the data and use statistical analysis to compare all of the experimental groups. This is then compared to the hypothesis to see if the data does or does not support the hypothesis. Through this method scientists draw conclusions about their hypothesis based on whether or not their experiment was successful.

Below are the instructions for each section of the project. For this assignment you will follow the steps of the scientific method and develop your own experiment.

You will need to include all of the following information:

Topic: Start by deciding what you would like to investigate. Your topic may be related to biology, the environment around you, or some other topic you are interested in.

Observations: Make a number of observations related to your topic. If the topic you chose isn't something you can observe around you then you may conduct research about your topic and record any noteworthy information. Include a paragraph describing your observations in your final submission.

Questions: Using your observations or research, think about your topic and ask some questions. Think about how it works or why it may behave a certain way. Come up with two or three questions about your topic.

Hypothesis: Use the questions you came up with to develop your hypothesis. This is a prediction of what you think will happen and should be able to be tested. A hypothesis is written in an "if, then" format. If this happens, then this will happen.

Experiment: Once you develop a hypothesis, think of how it could be tested in an experiment. What would you be testing? What would you measure? Remember that you need a control group. The purpose of this group is to serve as a reference that can be used to compare your experimental results to. This gives you something to compare with all the experimental groups and monitor any change. Record all of the following information about your experiment.

Independent Variable: This is what you are changing in the experiment.

Dependent Variable: This is what you are measuring.

Control Group: This is the group unaffected by the independent variable.

Experimental Groups: These are the groups affected by the independent variable and there should be multiple replications for each group.

Submission:

Be creative with how you present your information. This can be done in a list, in a chart, in paragraph form, or another way. Be sure to include your topic, observations, questions, hypothesis, and the details of your experiment. Be descriptive with your language in each section and use correct grammar.
