Question
Q2. The diagram shows an outline of part of the Periodic Table of Elements. (a) What is the name of the element with the symbol H? __ (b) In which regions of the Periodic Table are the following types of element found? (i) non-metals (such as oxygen and chlorine); region __ (ii) very reactive metals (such as sodium and potassium); region __ (iii) less reactive metals (such as copper and zinc). Region __ (c) Why is copper sulphate not found in the Periodic Table? __ . (d) An iron nail is placed into some blue copper sulphate solution. A reaction takes place between the iron and the copper sulphate.

Answer
(a) The element with the symbol
is Hydrogen.(b) (i) Non-metals are found on the right side of the Periodic Table.(ii) Very reactive metals are found in the leftmost column of the Periodic Table.(iii) Less reactive metals are found in the transition metals block in the middle of the Periodic Table.(c) Copper sulphate is not found in the Periodic Table because it is a compound, not an element.(d) When an iron nail is placed into some blue copper sulphate solution, a displacement reaction takes place. Iron displaces the copper from the copper sulphate solution, forming iron sulphate and copper.
Explanation
## Step 1: The symbol
represents Hydrogen in the Periodic Table of Elements.## Step 2: (i) Non-metals like oxygen and chlorine are found on the right side of the Periodic Table. They generally do not conduct electricity and are not malleable.(ii) Very reactive metals such as sodium and potassium are found in the leftmost column of the Periodic Table, known as Group 1 or the Alkali Metals.(iii) Less reactive metals like copper and zinc are found in the transition metals block, which is the large block in the middle of the Periodic Table.## Step 3: Copper sulphate is not found in the Periodic Table because it is a compound, not an element. The Periodic Table only includes pure elements, not compounds or mixtures.## Step 4: When an iron nail is placed into some blue copper sulphate solution, a displacement reaction takes place. This is because iron is more reactive than copper. The iron displaces the copper from the copper sulphate solution, forming iron sulphate and copper.
