- A.Group 3, Period 3
- B.Group 13, Period 3
- C.Group 3, Period 2

-
2.H2 is an isotope of hydrogen. In the modern periodic table it will be placed at the same position as hydrogen.
- A.It will be placed in a different group.
- B.It will be placed in a different period.
- C.It will be placed at the same position as hydrogen.
- D.It will not be placed in the periodic table.
-
3.Assertion: Non-metals are poor conductors of heat and electricity. Reason: Non-metals have 1, 2, or 3 electrons in their valence shell. Which of the following is correct?
- A.Both assertion and reason are true and the reason is correct.
- B.Both assertion and reason are true but the reason is incorrect.
- C.Assertion is true but the reason is false.
- D.Assertion is false but the reason is true.
-
4.Why does the reducing power of elements increase as one moves down a group in the periodic table?
- A.The nuclear charge increases, making it easier to attract electrons.
- B.The valence electrons are held more loosely by the nucleus, making them easier to lose.
- C.The atomic size decreases, increasing the electron density around the nucleus.
- D.The number of protons decreases, reducing the attraction for valence electrons.
-
5.The longest period of periodic table is :
- a.Sixth
- b.Second
- c.Fourth
- d.First
