Platinum is a precious metal used in a wide variety of products. Besides being used in fine jewelry, platinum is the catalyst found in the catalytic converters of automobile exhaust systems, and platinum-containing drugs like cisplatin are used to treat some lung and ovarian cancers. Answer the following questions about the element platinum.
a. What is its element symbol?
b. What group number and period are assigned to platinum?
c. What is its
d. Is platinum classified as a main group element, transition metal, or inner transition metal?
e. In what block does platinum reside?
f. What is unusual about the electronic configuration for platinum:

- Your friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.arrow_forwardIs 1s22s22p6 the symbol for a macroscopic property or a microscopic property of an element?

- Titanium and thallium have symbols that are easily confused with each other. Give the symbol, atomic number, atomic weight, and group and period number of each element. Are they metals, metalloids, or nonmetals?arrow_forwardThe chemical name for limestone, a compound of calcium, carbon, and oxygen, is calcium carbonate. When heated, limestone decomposes into solid calcium oxide and gaseous carbon dioxide. From the names of the products, tell where you might find the atoms of each element after the reaction.
