Step 1. Identify an element from the periodic table and assume that role

Step 2. Research the element using books, internet, or other materials

Step 3. Create a presentation about yourself (the element) that tells all about this element, its characteristics and its uses.

 

Your presentation must contain the following: Points Element symbol 5 Element Name 5 Atomic Number 5 Atomic Mass 5 Is it a solid, liquid or gas? 5 Is it a metal, nonmetal or metalloid? 5 Family Name or Rare Earth Element Series 5 Who discovered it? 5 When discovered? 5 How is it used? 5 Physical, chemical properties or unusual facts (must have 3) 5 Resources cited (minimum of 2) 5

Which of the following statements concerning the periodic table isincorrect?
A. Mendeleev received most of the credit for the early developmentof the periodic table.
B. The elements in a given group or family have similar chemicalproperties.
C. Mendeleev left spaces in his periodic table for undiscoveredelements.
D. All the elements are arranged in order of increasing atomicweight.
E. The chemical characteristics of the elements are periodicfunctions of their atomic numbers.

For each of the following elements, use the periodic table to give the chemical symbol, atomic number, and group number and to specify whether each element is a metal, nonmetal, or metalloid.  

1. strontium
2. silicon
3. sulfur
4. iodine
5. cesium

Choose one element from the periodic table and discuss its history, properties, and applications.

For each element, you must:

1. Discuss how & when it was first discovered.

2. Discuss the elements important chemical & physical properties including: phase at room temperature, melting point & boiling point, atomic mass, reactivity, and how many valence electrons the atom contains.

3. Discuss how it is found in nature.

4. Discuss at least two applications in industry or everyday life.
