Match (there may be more than one in each category or none at all)
Have outer electrons in d orbitals
Have outer electrons in p orbitals
Conduct electricity
Form ionic compounds with nonmetals
Usually take electrons to become anions
Are used in food, drink, and plumbing because it is less reactive and less likely to react with the food and liquids inside
Have the lowest electronegativity, making it most reactive and eager to give away electrons
Are used for a wide variety of purposes since it has more elements than any other block and each has unique physical and chemical properties often quite different from the elements above or beside it.
Alkali Metals
Alkali Earth Metals
Transition Metals
Post-Transition Metals
All of the above
None of the above
Match the following elements with their description
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Zinc | arrow_right_alt | The most abundant element on earth, this transition metal forms +3 Ferric and +2 Ferrous cations in our blood or metallic bonds in many useful alloys. |
Mercury | arrow_right_alt | When alloyed with copper, this transition metal forms a durable, shiny, coins much cheaper than the silver coins they replaced. |
Aluminum | arrow_right_alt | This uniquely colored transition metal is widely used for electrical wiring, plumbing, and durable roofing which develops a protective green patina made from its reaction with acids in the air. |
Silver | arrow_right_alt | This transition metal used to coat iron in galvanized steel roofing and forms +2 cations needed by our immune system to fight disease and reduce allergies. |
Tin | arrow_right_alt | The only transition metal which is liquid at room temperature, it is useful in lighting and scientific instruments but can accumulate in fish and our bodies and poison us. |
Potassium | arrow_right_alt | A post-transition metal often used for cans to store food, it is more electronegative than most metals and does not react easily with weak acids in food. |
Nickel | arrow_right_alt | The most common element in the earths crust, this post-transition metal is less dense than the iron in the earth's core and is widely used in pressurized drink containers, airplanes, car parts, and construction when weight is important. It forms a +3 cation in ionic compounds. |
Iron | arrow_right_alt | This dense post-transition metal is used for plumbing, bullets, and to stop x-rays, since it has a larger nucleus than any other stable element |
Copper | arrow_right_alt | This highly conductive transition metal is the most common "noble metal", whose beauty and resistance to reaction with other elements has made it widely used for money and jewelry throughout history |
Lead | arrow_right_alt | Is an alkali metal with 1 electron in its 4s orbital |
Which of the following statements is True?
