(a)
Interpretation:
The statement "in the modern periodic table, the elements are arranged in order of increasing
Concept introduction:
A periodic table is an arrangement of elements based on their
(b)
Interpretation:
The statement "elements in a period have similar chemical properties" is to be corrected.
Concept introduction:
A periodic table is an arrangement of elements based on their atomic number, properties and electronic configuration. The table is arranged into groups and periods. The elements which are metallic in nature, occupy the large lower-left portion of the table. The non-metals occupy the small upper-right portion of the table. Metalloids lie along the staircase line. Elements which appear in the same group have similar behaviour.
(c)
Interpretation:
The statement "elements can either be classified as either metalloids or non-metals" is to be corrected.

- 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.
