Sample questions

1. Which of the following elements exhibits the highest ionization enthalpy among the given elements?

   1. Sodium (Na)
   2. Magnesium (Mg)
   3. Aluminum (Al)
   4. Silicon (Si)
   Show answer

   Answer: D. Silicon (Si)

   Ionization enthalpy generally increases across a period due to increasing effective nuclear charge. Silicon (Si) is to the right of Sodium (Na), Magnesium (Mg), and Aluminum (Al) in the same period (Period 3), thus it has a higher effective nuclear charge and requires more energy to remove an electron.

2. Oxidizing strength generally:

   1. Increases across a period and decreases down a group
   2. Decreases across a period and increases down a group
   3. Increases across a period and increases down a group
   4. Decreases across a period and decreases down a group
   Show answer

   Answer: A. Increases across a period and decreases down a group

   Oxidizing strength is the tendency of an element to gain electrons. This tendency increases with increasing electronegativity (across a period) and decreases with increasing atomic size and shielding (down a group).

3. An element with a small atomic radius and high electronegativity is likely to be a:

   1. Metal
   2. Non-metal
   3. Metalloid
   4. Noble gas
   Show answer

   Answer: B. Non-metal

   Non-metals generally have smaller atomic radii and higher electronegativity compared to metals. They tend to gain electrons.

4. The most electronegative element is:

   1. Oxygen (O)
   2. Nitrogen (N)
   3. Fluorine (F)
   4. Chlorine (Cl)
   Show answer

   Answer: C. Fluorine (F)

   Fluorine (F) is the most electronegative element in the periodic table due to its small atomic size and high effective nuclear charge, giving it the strongest attraction for shared electrons.

5. Which of the following elements has the smallest atomic radius?

   1. Sodium (Na)
   2. Magnesium (Mg)
   3. Aluminum (Al)
   4. Silicon (Si)
   Show answer

   Answer: D. Silicon (Si)

   Atomic radius decreases across a period. Silicon (Si) is to the right of Sodium (Na), Magnesium (Mg), and Aluminum (Al) in Period 3, having the highest effective nuclear charge among them and thus the smallest atomic radius.
