Interpretation Introduction To determine: The de Broglie wavelength of an electron traveling with the velocity of 1 . 3 5 × 1 0 5 m / s . Explanation Given: The velocity of an electron is 1 . 3 5 × 1 0 5 m/s . Explanation: The de Broglie wavelength can be calculated as follows: λ = h m v Here, λ is the de Broglie wavelength, h is Planck’s constant, m is the mass of the subatomic particle, and v is the velocity. The mass of an electron is 9.1 × 10 − 31 kg and the value of Planck’s constant is 6.626 × 10 − 34 kg m 2 /s . Substitute the values in the above equation: λ = 6.626 × 10 − 34 kg m 2 /s 9

Atomic Structure

The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explain…

Shape of the D Orbital

Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
