In cathode ray experiment why does only electron move to protons

Why not protons move to electron? Please tell me now because I have test tomorrow?

Q. Why can only electrons move and get transferred? Why not protons?

Q.

I learnt this in atoms and molecules chapter "Two protons will also tend to repel each other because they both have a positive charge. On the other hand, electrons and protons will be attracted to each other because of their unlike charges."but I have a doubt, that is, if protons can attract electrons,then why electrons in the atom is revolving around the protons and not attracting it.

Q. In the module of chapter-Metals and Non Metals,you have explained the case of lithium metal,at the atomic level,that why it is so reactive (because there are 3 protons attracting the Valence electron, and 2 electrons in the k-shell repelling the valence electron, thats why the net resultant force is less) So can you please explain me the case of Sodium and calcium that why less energy is required to kick out valence electrons,like you have explained in the case of litium i.e at the Atomic level

Q. How does a fuse work. Can you please send me the answer fastly
in priyam.sarkarmsd@gmail.com.Because I have a test tomorrow.

Q. Ever wonder when you look at things in the surrounding, what are they made up of? No? Everything in your surrounding including you, are made up of atoms. Now what is an atom? Atom is made up of electrons, protons and neutrons. Electrons revolve around the protons and neutrons. Protons are positively charged and electrons are negatively charged while neutrons have no charge. Protons are not free to move, hence only electrons can move if we provide them enough energy. The particle which is responsible for the heating of appliances is ______.
