I’m not quite sure what you are trying to say but this sounds like induction. If you can put the question in the comments, preferably with less question marks, I might be able to assist.

How dose an atom change if all of its electrons are removed
cluponka [151]

Answer:

The atom becomes a positively charged ion.

Explanation:

  1. The building blocks of an atom are protons, neutrons, and electrons.
  2. The protons and neutrons present in the core of the atom are called nucleus.
  3. The electrons are scattered in an ordered way around the nucleus.
  4. The protons are positively charged and the electrons are negatively charged particles. The neutrons do not possess any charges.
  5. Binding energy is supplied to the atom to remove an electron.
  6. It is possible to remove the electrons of the lighter elements.
  7. When an electron is removed from the hydrogen atom. It becomes positively charged ion or simply proton.
  8. When all of the electrons are removed from the helium atom, it becomes a positively charged α particle.
  9. It is practically very difficult to remove all of the electrons from the heavier elements.
  10. When all of the electrons are removed from an atom it becomes an unstable positively charged ion.

(a) As a soap bubble thins it becomes dark, because the path length difference becomes small compared with the wavelength of lig
OLga [1]

Answer:

t< 75 nm

Explanation:

A soap bubble is a thin film where when the beam enters the film it has a 180º phase change due to the refractive index and the wavelength changes between

              λ = λ₀ / n

In the case of constructive interference in the curve of the spherical film it is

              2 nt = (m + ½) λ₀

Where t is the thickness of the film and n the refractive index that does not indicate that we use that of water n = 1.33, m is an integer. The thickness of the film for the first interference (m = 0) is

              t = λ₀ / 4 n

A thickness less than this gives destructive interference.

Let's look for the thickness for the visible spectrum

Violet light λ₀ = 400 nm = 400 10⁻⁹ m

      t₁ = 400 10⁻⁹ / 4 1.33

      t₁ = 75.2 10-9 m

Red light λ₀ = 700 nm = 700 10⁻⁹ m

       t₂ = 700 10⁻⁹ / 4 1.33

       t₂ = 131.6 10⁻⁹ m

Therefore, for all wavelengths to have destructive interference, the thickness must be less than 75 10⁻⁹ m = 75 nm

b) a film like eta is very thin, it is achieved when gravity thins the pomp, but any movement or burst of air breaks it,
