The principal quantum number (n) indicates the energy level; for the third energy level, n = 3.

Sodium has an atomic number of 11, and its outermost electron is in the 3rd shell, so n=3.

Sodium has the electronic configuration of 1s² 2s² 2p⁶ 3s¹, so the principal quantum number for the outermost electrons is 3.

The ground state of hydrogen corresponds to n = 1.

The principal quantum number (n) indicates the energy level. For the third energy level, n = 3.

Chlorine has an atomic number of 17, and its outermost electrons are in the 3rd shell, so n=3.

Potassium has an atomic number of 19, and its outermost electron is in the n=4 shell.

Chlorine has an atomic number of 17, and its outermost electrons are in the n=3 shell.

A manometer is used to measure the pressure difference between two points in a fluid.

A photodiode operates on the principle of the photoelectric effect, where light generates electron-hole pairs.

The principle behind a thermos flask is insulation, which minimizes heat transfer.

A lever operates on the principle of mechanical advantage, allowing a smaller force to lift a larger load.

A hydraulic lift operates based on Pascal's law, which states that pressure applied to a confined fluid is transmitted undiminished in all directions.

A galvanometer works on the principle of the magnetic force acting on a current-carrying conductor placed in a magnetic field.

Bernoulli's Principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure.

Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Bernoulli's Principle states that an increase in the velocity of a fluid occurs simultaneously with a decrease in pressure.
