FAQs on Orbitals Video Lecture - Chemistry Class 11 - NEET

1. What are orbitals in chemistry?
Ans. Orbitals in chemistry refer to the regions of space around an atomic nucleus where an electron is most likely to be found. They are represented as a three-dimensional region where an electron has a high probability of being located.
2. How are orbitals different from electron shells?
Ans. Orbitals and electron shells are related but different concepts in chemistry. Electron shells are energy levels that surround the nucleus and contain one or more orbitals. Orbitals, on the other hand, are specific regions within the electron shells where electrons are likely to be found.
3. How many types of orbitals are there?
Ans. There are four types of orbitals: s, p, d, and f. The s orbital is spherical in shape, the p orbitals are dumbbell-shaped, the d orbitals are complex and have various shapes, and the f orbitals are even more complex and have different orientations.
4. What is the maximum number of electrons that can occupy each orbital type?
Ans. The maximum number of electrons that can occupy each orbital type is as follows: s orbital - 2 electrons, p orbital - 6 electrons, d orbital - 10 electrons, and f orbital - 14 electrons. These numbers are determined by the Pauli exclusion principle and the Aufbau principle.
5. How do orbitals determine the chemical properties of elements?
Ans. The arrangement and distribution of electrons in orbitals play a crucial role in determining the chemical properties of elements. The number and type of orbitals filled by electrons determine the element's electron configuration, which in turn determines its reactivity, bonding behavior, and overall chemical behavior.
