Sample questions
-
1.Why does the oxidising power of elements increase on moving from left to right along a period in the periodic table?
- A.Atomic size increases, making electron gain easier
- B.Nuclear hold on electrons strengthens, enhancing electron acceptance
- C.Electronegativity decreases, reducing oxidizing ability
- D.Metallic character increases, preventing electron gain
-
2.In Period 3 of the periodic table, which of the following is the most metallic element?
- A.Sodium
- B.Magnesium
- C.Aluminium
- D.Silicon
-
3.... (Mendeleev/Moseley) left gaps in the periodic table for the undiscovered elements.
- a.Moseley
- b.Mendeleev
- c.John Newlands
- d.William Ramsay
-
4.What are Lanthanides and Actinides in the context of the periodic table?
- A.Lanthanides are elements with atomic numbers 57 to 71, and Actinides are elements with atomic numbers 89 to 103, both classified as inner transition elements.
- B.Lanthanides and Actinides are groups of elements located in the main body of the periodic table, representing transition metals.
- C.Lanthanides are elements with atomic numbers 58 to 72, and Actinides are elements with atomic numbers 90 to 104, both part of the s-block.
- D.Lanthanides and Actinides are synthetic elements only, with no naturally occurring members in either series.
-
5.The non-metallic properties of elements from left to right in a periodic table
- A.increases
- B.decreases
- C.remains same
- D.first increases and then decreases
