The nuclear reactions which are under experimenter's control are said to be controlled nuclear reactions. In this, you can maintain the speed of the incident particle. α and β-decay process are examples of non-controlled nuclear reactions.
I can't see the picture, but in general, I believe it is in dropping from the first energy level above the ground state, to the ground state.
Answer:
alright
Explanation:
Hess law is the enthalpy change for a reaction that is carried out in a series of steps is equal to the sum of the enthalpy changes for the individual steps. Consistent with the law of conservation of energy. Starting and final conditions must be the same.
Sodium (Na) has only one electron in its outer electron shell, as shown in Figure 1. Once again, gaining one electron is more energy efficient than losing seven. As a result, it appears to obtain an electron, resulting in an ion with 17 protons, 17 neutrons, and 18 electrons, and a net negative charge (–1).
