1. According to Rutherford and soddy's law of Beta emission:

3. According to Rutherford and soddy's law of Alpha emission:

4. The process in which two or more light nuclei are combined to form a single nucleus with the release of tremendous amount of energy is called a nuclear fusion. The inner core of Sun is at very high temperature and is suitable for fusion. In fact the source of energy of Sun and other stars is nuclear fusion reactions.
Yes a liquid is the state of matter
The number of protons in X would be 6 while that of Y would also be 6. Thus, the two atoms would be isotopes of the same element.
<h3>Atomic properties of atoms</h3>
The mass number of an atom is the sum of protons and neutrons present in the atom.
For X with mass number 12 and neutron number 6, the number of protons would be:
12 - 6 = 6 protons
For Y with mass number 13 and neutron number 7, the number of protons would be:
13 - 7 = 6 protons.
Thus, both atoms have the same number of protons, meaning that they are likely isotopes of the same element.
