Concept explainers
Interpretation: The number of electrons present in beryllium ion’s outer energy level is to be stated.
Concept introduction: The strategy for drawing Lewis structure is mention below.
- Calculate the number of valence electrons present in the molecule.
- Calculate the electron pairs by diving number of valence electrons by 2.
- Determine the bond pairs.
- Determine the lone pairs.
- Check whether the central atom satisfies octet rule.
Answer to Problem 19STP
The number of electrons present in beryllium ion’s outer energy level is zero (0). Therefore, option (A) is the correct option.
Explanation of Solution
Reason for correct option: The
Reason for incorrect option: The number of electrons present in beryllium ion’s outer energy level is zero. So, B, C, D and E are incorrect options.
