1. The problem statement, all variables and given/known data the first nuclear reaction induced in a laboratory can be represented by N147 + He42 = O178 + H11 what information can be obtained from the symbol O178 2. Relevant equations 3. The attempt at a solution The number 17 represents the atomic mass, which is also known as the nucleon number From the nucleon number we are able to find out the number of neutron and also able to determine the mass of O The number of 8 is the number of proton. thats all i can get from it and more info from it>?
