Using the example of the first nuclear reaction carried out by Rutherford, show how the laws of conservation

Using the example of the first nuclear reaction carried out by Rutherford, show how the laws of conservation of electric charge and mass number are fulfilled.

14 / 7N + 4 / 2Не -> 17 / 8О + 1 / 1Н Law of conservation of electric charge: the sum of charge
the number of elements before the reaction is equal to the sum of the charge numbers after the reaction.
7 + 2 = 8 + 1
The law of conservation of mass numbers: the sum of the mass numbers of elements before the reaction
equal to the sum of the mass numbers after the reaction.
14 + 4 = 17 + 1

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
