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>?

That is about it. That is what O178 means. Atomic mass = 17 and atomic number = 8.

thx so much
cant imagine i done the right answer
yay

I don't know much about nuclear physics but wouldn't you be able to obtain the number of neutrons? 17-8 = 9 neutrons

Good point. The number of neutrons is always the atomic mass - atomic number.
