Answer:

There is a positive charge in the nucleus

Explanation:

The concept was envisaged by Ernest Rutherford. He was a renowned scientist and chemist. In the hypothesis, he proposed that an atom must have a concentrated positive charge around the nucleus or in the nucleus that contains the atom's mass. He also suggested that the nucleus contains a particle with a positive charge that was called a proton.

When a neutral hydrogen atom loses an electron, and positively-charged particles should remain. A proton should be 1840 times heavier than an electrons. Cathode rays should be attracted to a positively- charged plate.

The wavelength of a particular color of violet light is 433 nm. The energy of this wavelength of light is kJ/photon. (109 nm = 1
mash [69]

Answer:

4.59 × 10⁻³⁶ kJ/photon

Explanation:

Step 1: Given and required data

  • Wavelength of the violet light (λ): 433 nm
  • Planck's constant (h): 6.63 × 10⁻³⁴ J.s
  • Speed of light (c): 3.00 × 10⁸ m/s

Step 2: Convert "λ" to meters

We will use the conversion factor 1 m = 10⁹ nm.

433 nm × 1 m/10⁹ nm = 4.33 × 10⁷ m

Step 3: Calculate the energy (E) of the photon

We will use the Planck-Einstein's relation.

E = h × c/λ

E = 6.63 × 10⁻³⁴ J.s × (3.00 × 10⁸ m/s)/4.33 × 10⁷ m

E = 4.59 × 10⁻³³ J = 4.59 × 10⁻³⁶ kJ
