Question
Download Solution PDFAccording to the Bohr's model, what is the maximum number of electrons for the second energy level?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 8.
Key Points
- According to the Bohr model, the second energy level can hold a maximum of 8 electrons.
- Electrons in an atom are arranged in energy levels or shells, which are denoted by the principal quantum number (n).
- The formula to determine the maximum number of electrons in a shell is given by 2n2, where n is the principal quantum number.
- For the second energy level (n=2), the maximum number of electrons is calculated as 2(2)2 = 8.
- This concept is foundational to understanding the electron configuration of atoms and their chemical properties.
Additional Information
- Principal Quantum Number (n)
- It denotes the energy level of an electron within an atom.
- The value of n determines the size and energy of the orbital.
- Higher values of n correspond to higher energy levels and larger orbitals.
- Bohr Model
- Proposed by Niels Bohr in 1913, it describes electrons orbiting the nucleus in fixed energy levels.
- Electrons can jump between energy levels by absorbing or emitting specific amounts of energy.
- The model helped explain the spectral lines of hydrogen.
- Electron Configuration
- It describes the distribution of electrons in the different energy levels or orbitals of an atom.
- It follows a specific order based on the Aufbau principle, Pauli exclusion principle, and Hund's rule.
- Electron configuration helps predict chemical behavior and bonding.
- Aufbau Principle
- It states that electrons fill lower energy orbitals first before moving to higher energy orbitals.
- This principle guides the order in which atomic orbitals are filled.
