Describe the shape of 's'-orbitals.
Describe the shape of 's'-orbitals.
The distribution of electrons in '1s' is symmetrical around the nucleus, and there is an equal chance of finding the 's' electron in any direction with respect to the nucleus. The surface of the sphere represents the probability of finding the 's' electron.
What is the difference between an orbit and an orbital?
What is the difference between an orbit and an orbital?
An orbit represents a definite circular path at a definite distance from the nucleus in which the electron revolves around the nucleus, while an orbital signifies a region in three-dimensional space around the nucleus where there is a maximum probability of finding the electron.
What is the shape of 'p'-orbitals?
What is the shape of 'p'-orbitals?
A 'p' orbital is two-lobed and like a dumbbell. The probability of finding an electron is concentrated along one direction. There are three 'p' orbitals: p_{x}, p_{y}, and p_{z}, which are oriented along the three mutually right angle axes x, y, and z.

Study Notes
Shape of 's'-orbitals
- 's'-orbitals are spherical in shape.
- They are centered around the nucleus with a uniform electron density distribution in all directions.
- The size of 's'-orbitals increases with higher principal quantum numbers (n).
Difference between an orbit and an orbital
- An orbit refers to a defined circular path around the nucleus where an electron is expected to be found.
- An orbital is a mathematical function that describes the probability distribution of an electron's position, encompassing regions of space where an electron is likely to be located.
Shape of 'p'-orbitals
- 'p'-orbitals have a dumbbell or figure-eight shape.
- There are three distinct 'p'-orbitals: p_x, p_y, and p_z, oriented along the corresponding axes in three-dimensional space.
- Each 'p'-orbital contains two lobes, with a nodal plane at the nucleus where the probability of finding an electron is zero.
Direction of the {}p_{x}^{\prime} orbital
- The most likely direction to find an electron in the {}p_{x}^{\prime} orbital is along the x-axis.
- The p_x orbital's lobes extend outwards along the positive and negative x-dimension, indicating high electron probability in those regions.
Energy of electrons in an atomic orbital
- Electrons in atomic orbitals possess quantized energy levels.
- The energy associated with an electron in an orbital depends on the principal quantum number (n) and the angular momentum quantum number (l).
- Higher energy levels correspond to higher values of n and the specific type of orbital (s, p, d, f) determines additional energy variations.
