APB Unit 1 - Inorganic Chemistry Review #GoBioRams

Biologists ALWAYS have a periodic table around somewhere. When looking at it, where do you find the elements that form cations, are malleable, and conduct electricity?

• These elements are found on the left side of the stair-step.

• These elements are found on the stair-step.

• These elements are found on the right side of the stair-step.

• These elements are found on the right-most period of the periodic table.

Where on the periodic table would you find the elements that can have multiple oxidation states depending on what other element(s) they are reacting with?

• These elements are found on the left side of the stair-step.

• These elements are found in the area known as the transition metals, which is located in the "valley" to the left side of the stair-step.

• These elements are found on the right side of the stair-step.

• These elements are found on the period that is farthest on the right of the periodic table.

Which group of elements are chemically reactive, produce toxic, colored fumes, are brittle, are not magnetic, and do not conduct electricity?

• The metals, which are on the left side of the stair-step.

• The metalloids or semi-metals, which are found on the stair-step.

• The non-metals, excluding the Noble Gases, which are found on the right side of the stair-step.

• All chemicals on the periodic table fit this description.

Where are the radioactive elements located on the periodic table?

• There are no naturally occurring radioactive elements on the periodic table.

• Radioactive elements can be found towards the bottom of the periodic table in areas such as the metals, transition metals, and the Actinide and Lanthanide series.

• Radioactive elements are found in the upper right-hand corner of the periodic table.

• Radioactive elements are scattered throughout the periodic table and are in no particular order.

Excluding the Noble Gases, which are chemically inert, which area of the periodic table contains the most electronegative elements?

• The most electronegative element is Francium (Fr), which is located at the bottom-left corner of the periodic table.

• The most electronegative element is Fluorine (F), which is located at the top-right corner of the periodic table.

• The most electronegative element is Fermium (Fm), which is located at the bottom and middle of the periodic table.

• All elements are equally electromagnetic, a.k.a. they all want electrons just as much as any other element when they are chemically reacting.

Answer explanation

If you have't figured out yet that you should probably open up the IUPAC Periodic Table... https://sciencenotes.org/wp-content/uploads/2019/01/PeriodicTableoftheElements.pdf

Check which of the following elements normally produce diatomic gases.

• Oxygen Gas or O₂

• Fluorine Gas or F₂

• Nitrogen Gas or N₂

• Hydrogen Gas or H₂

• Chlorine Gas or Cl_2

Answer explanation

If you look at the periodic table, here is a "cheat." There are 8 or (1+7) or (H + N, O, F, Cl, Br, I, At). We think At will be diatomic.

Which elements are in liquid form on Earth?

• Mercury (Hg)

• Rubidium (Rb)

• Cesium (Cs)

• Bromine (Br)

• All of the above could be found naturally as a liquid on Earth.

Answer explanation

You may also find Gallium (Ga) and Francium (Fr) as liquids here on Earth.

Which group of metals can form 2+ cations and are commonly found in crystal formations here on Earth?

• Alkaline Metals

• Alkaline Earth Metals

• Chalcogens

• Halides

• Noble Gases.

Which group of metals form 1+ cations, are chemically very reactive, and can be found in many strong bases?

• Alkaline Metals

• Alkaline Earth Metals

• Chalcogens

• Halides

• Noble Gases

Answer explanation

That is why bases are sometimes referred to as alkaline.
