Explanation

Orbitals that have the same energy level are called degenerate orbitals.

This concept is important in understanding electron behavior and how they fill atomic orbitals, following principles like the Aufbau principle and Hund's rule.

For example, in a hydrogen atom, all orbitals with the same principal quantum number (n) are degenerate. 

Explanation

• Gamma rays have the highest energy among the options.
• They are electromagnetic waves with extremely high frequency and short wavelength.
• It gives them more energy compared to Alpha, Beta, and X-rays.

Explanation

The K orbit, also known as the first electron shell.

• It can hold a maximum of 2 electrons.

The L orbit, also known as the second electron shell.

• It can hold a maximum of 8 electrons.

The M orbit, also known as the third electron shell.

• It can hold a maximum of 18 electrons.

Explanation

 The energy required to break down a nucleus into its constituent protons and neutrons is called nuclear binding energy.

Explanation

σ to σ* transition requires the highest energy.

Because it involves the breaking of a strong sigma bond.
