Summary

The job description should accurately reflect the duties and responsibilities of the position. When well-written, it produces a realistic picture of a job and answers the question, “What does the person in this role actually do?”

A job description not only describes the position’s respo...

Description

Periodic Table Virtual Lab Type your answers in BLUE or RED!!! Procedure 1. Visit Syngenta Periodic Table of Elements. 2. Run your cursor across the group number at the top of each column. What are the names of the following groups? a. Group 1: b. Group 2: c. Group 7: d. Group 0: 3. Run your cursor across the states of matter (solid, liquid, gas) at the bottom of the page and watch the applicable elements become highlighted. a. In what state do most elements on the periodic table occur? b. What two elements exist in the liquid phase? c. What is the state of matter of all elements listed in group 0? 4. Use your cursor to select each of the following elements and answer the accompanying questions. a. Carbon, C i. In what state of matter does carbon exist? ii. List three uses of carbon. b. Potassium, K i. List three uses of potassium. ii. List one interesting fact about potassium. c. Gold, Au i. In what group is gold located? ii. List three uses of gold. d. Strontium, Sr i. What is the atomic mass of strontium? ii. For what is strontium named?

e. Select one element of your choosing and answer the following: i. What is the name and symbol of this element? ii. In what group is this element located? iii. In what state of matter does this element exist? iv. List one use of this element. v. List one fact about this element. **STOP HERE** Reaction Zone not working. Please submit questions 1-4 to the Periodic Table Virtual Lab Dropbox. 5. Click on the “Reaction Zone” link at the bottom right of the page (you may need to copy and paste the link into Internet Explorer if Google Chrome does not load the simulation). 6. Under “Reactivity Trends in Group 1”, click “TEST THIS GROUP”. Test each of the following combinations of substances and record your observations in the data table below. Lithium

Sodium

Potassium

Rubidium

Caesium

Water

bubbles

gas productions

catches fire

sinks explodes

sinks explodes

Oxygen

burn lightly

oxidized when freshly cut burned yellow flames

tamishes shortly melts that reacts

burns as soon as it touches oxygen

burns as soon as it touches oxygen

Chlorine

burns briefly

burns with fumes produced

burns with lilac flame color

extremely violent

extremely violent

a. Compare the reactivity of the metals in group 1. (ie: Which are least/most reactive?)The reactivity of alkali metals increases from the top to the bottom of the group, so lithium (Li) is the least reactive alkali metal and francium (Fr) is the most reactive. b. So…as you move down a group on the periodic table, metal reactivity _increase_________ (increases/decreases). 7. Click on the “Reaction Zone” link at the bottom right of the page to get back to the original screen. 8. Under “Reactivity of Metals”, click “TEST THIS GROUP”. Test each of the following combinations of substances and record your observations in the data table below.

Acid

Magnesium

Aluminum

Zinc

Iron

Copper

heats up

the aluminum melts down

bubbles formed

slow reaction and frzzes

brown gas is formed

a. Compare the reactivity of the metals with concentrated acid versus dilute acid..Concentrated acid reactions were much faster than the diluted acid. b. Which combination yields a more vigorous reaction?concentrated acid water

c. *A chemical property of most metals is that they react with acid. 9. Click on the “Reaction Zone” link at the bottom right of the page to get back to the original screen. 10. Under “Reactivity Series of Halogens”, click “TEST THIS GROUP”. Test each of the following combinations of substances and record your observations in the data table below. Fluorine

Chlorine

Bromine

Iodine

it dissolves into water

slightly dissolves in water giving off a purple/ pink tink

the water bubbles

Water

water burn

Sodium

burns with a yellow color while a salt forms

Aluminum

turn red

and the water starts to turn yellow burns a red flame whie fumes appear explodes and causes white fumes

explodes with a yellow flame and leaves alot of fume spark a burning with a bright falme

heats up and catches on fire purple vapor appears then burns a bright flame

a. Compare the reactivity of the nonmetals in group 7. (ie: Which are least/most reactive?))fluorine is the most reactive and iodine is the least reactive b. So…as you move down a group on the periodic table, nonmetal reactivity __________ (increases/decreases)....
