Question 3
Which of the following atoms has least attraction for bonding electrons? A Carbon B Nitrogen C Phosphorus D Silicon
Worked Solution & Example Answer:Which of the following atoms has least attraction for bonding electrons? A Carbon B Nitrogen C Phosphorus D Silicon - Scottish Highers Chemistry - Question 3 - 2015
Step 1
Identify the atom with the least attraction for bonding electrons
Answer
To determine which atom has the least attraction for bonding electrons, we need to consider the concept of electronegativity, which refers to the tendency of an atom to attract electrons towards itself in a bond. Among the given options:
- Carbon (C) has a relatively high electronegativity (around 2.5).
- Nitrogen (N) also has a high electronegativity (around 3.0).
- Phosphorus (P) has a lower electronegativity compared to C and N (approximately 2.1).
- Silicon (Si), which is in the same group as Carbon, has an electronegativity of about 1.9.
Based on electronegativity values, Silicon (D) has the least attraction for bonding electrons.
