go to periodic table
look for the element you want
find the atomic number on the top right hand side of the element
atomic number = equal to number of proton.
find atomic mass bottom right hand side of the element
atomic mass - atomic number = neutron
i hope this will help
Na atomic number 11 and mass number 23
protons 11
neutron =23-11=12
I’m not 100% sure but I think so
Hypothesis is a smart guess that you make on the result of your experiment. You make this even before doing the experiment through inferential analysis.
