Explanation:
The different subatomic particles in an atom are the:
- Protons which are the positively charged particles.
- Electrons which are the negatively charged particles.
- Neutrons which do not carry any charges.
Protons and neutrons are located in the nucleus of an atom which is the tiny center of the atom.
Electrons orbits around the nucleus and fill the rest of the volume of atom.
The correct answer is option B. i.e. the number of protons is increased.
In beta-particle emission, a neutron is changed into proton, electron and electron neutrino. The electron is emitted as beta particle and the proton remains inside the atom. Thus, the mass number remains same but the atomic number increases by one.
Answer:
Yes because all solids have some thermal energy, its atoms do vibrate. However, this movement is very small and very rapid, and cannot be observed under ordinary conditions. When heat is added a solid can become a liquid.

Answer:
The entropy of the final solution decreases, as the reaction disorder is less.
Explanation:
The higher the temperature, the greater the heat of the reaction and the greater the disorder it has, so the entropy will increase ... But this is not the case, since the solution cools, decreasing the entropy proportionally.
