Sample questions

1. Who is credited with the creation of the Periodic Table?

   1. Dmitri Mendeleev
   2. Albert Einstein
   3. Marie Curie
   4. Isaac Newton
   Show answer

   Answer: A. Dmitri Mendeleev

   Dmitri Mendeleev is credited with creating the first Periodic Table which organized elements by atomic weight.

2. Which group of the Periodic Table is known for elements that typically form salts with metals?

   1. Group 1
   2. Group 2
   3. Group 17
   4. Group 14
   Show answer

   Answer: C. Group 17

   Group 17 is the halogen group, and these elements often combine with metals to form salts.

3. How many periods are there in the Periodic Table?

   1. 4
   2. 6
   3. 7
   4. 8
   Show answer

   Answer: C. 7

   The Periodic Table consists of 7 periods which represent the number of electron shells in the elements.

4. Why do elements in the same group have similar chemical properties?

   1. Same atomic nuclei
   2. Same electron configuration
   3. Same number of valence electrons
   4. Same density
   Show answer

   Answer: C. Same number of valence electrons

   Elements in the same group have the same number of valence electrons, leading to similar chemical properties.

5. Where are the nonmetals located in the Periodic Table?

   1. Left side
   2. Centre
   3. Right side
   4. Bottom rows
   Show answer

   Answer: C. Right side

   Nonmetals are typically found on the right side of the Periodic Table, as they have high electronegativities and ionization energies.
