Answer 1

Answer:

yes it is easier to remove fresh stains as when something is just spilt it is still wet and the cloth hasn't absorbed it yet, but when it is caused a few ...is easier to remove an orbital electron from an atom, but quite difficult to remove a nucleon from a nucleus. <br> Statemet-2: An electron is much lighter than a nucleon.

Answer 2

Explanation:

It is harder to remove an electron from copper than sodium, the work function of copper is greater.

ω = hvₙ = hc/λₙ

∴ λₙ α 1/ω

As threshold wavelength is inversely proportional to the work function, its value will be more for sodium.

Hope it helps!
