how many electrons are there in the L shell of boron?
Correct answer: A. 3
- A. 3
- B. 2
- C. 1
- D. 4
Explanation
Boron (B) has an atomic number of 5. In the L shell, the 2s subshell can hold a maximum of 2 electrons, and the 2p subshell can hold a maximum of 6 electrons. However, in the case of boron, the 2s subshell is fully occupied with 2 electrons, and there is 1 electron in the 2p subshell. Therefore, the L shell of boron contains a total of 3 electrons. This option is also incorrect. Boron (B) does have 2 electrons in the 2s subshell of the L shell, but it also has an additional electron in the 2p subshell. Therefore, the L shell of boron contains a total of 3 electrons, not 2. This option is incorrect because boron (B) has a total of 3 electrons in its L shell. This option is incorrect because boron (B) has a total of 3 electrons in its L shell.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
