(a)
Interpretation:
An element with largest atomic radius in the given set has to be identified.
Concept introduction:
Atomic radii:
It is the distance between center of nucleus and outermost orbital of an atom. In periodic table, top to bottom atomic radii increases due to addition of electrons in new orbitals and decreases across the periods due to increase in effective nuclear charge.
(b)
Interpretation:
An element with smallest ionization energy in the given set has to be identified.
Concept introduction:
Ionization energy:
In a gaseous state isolated neutral atom, the amount of energy required to eject an electron from outermost shell is known as ionization energy. Ionization energy increases from left to right across periods due to increase of effective nuclear charge. Ionization energy decreases down the group due to addition of electrons enters into new orbital which is far from nucleus.

- The U. S. Environmental Protection Agency (EPA) sets limits on healthful levels of air pollutants. The maximum level that the EPA considers safe for lead air pollution is 1.5 μg/m³ Part A If your lungs were filled with air containing this level of lead, how many lead atoms would be in your lungs?

- A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.arrow_forwardNonearrow_forwardNonearrow_forward
