Why do electrons closer to nucleus have
Less energy than electrons first away?
Thanks

Rajini said:The electrons that are closer to nucleus require more energy to remove from the atom.
Energy levels in atoms refer to the different levels of energy that electrons can occupy within an atom. These energy levels are represented as shells or orbitals, with the lowest energy level being closest to the nucleus and the highest energy level being furthest away.
The number of energy levels in an atom depends on the number of electrons it has. Each energy level can hold a certain number of electrons: the first level can hold 2, the second level can hold 8, the third level can hold 18, and so on. However, not all atoms have electrons in all of these energy levels.
Electrons can move between energy levels by gaining or losing energy. This can happen through interactions with other atoms, photons of light, or thermal energy. When an electron gains energy, it can move to a higher energy level. When it loses energy, it can move to a lower energy level.
When electrons move to a higher energy level, they become excited. This means they have more energy and are less stable. The electrons will eventually release this excess energy, often in the form of light, and return to a lower energy level. This process is known as emission and is the basis for many scientific applications, such as fluorescent lights and lasers.
The energy levels in atoms play a crucial role in determining the chemical and physical properties of elements. The specific arrangement of electrons in an atom's energy levels determines its reactivity, ability to form bonds, and many other characteristics. Understanding energy levels in atoms is essential for understanding the behavior and properties of matter at a fundamental level.
