Atomic elements consist of a nucleus that contains protons and neutrons. Protons carry a positive charge whilst neutrons are electrically neutral. In light elements with an atomic number less than 20, the neutron to proton ratio is generally equal to 1:1. This changes for heavier elements since the Coulomb interaction between many protons gets stronger and demands more neutrons for the nucleus to remain stable.
Explanation:
all atoms have a dense central core Corvette Atomic nucleus forming the nucleus or two kinds of particles protons which have a positive electric charge and neutrons have no charge
It is 50. The answer is 50. 10x5=50 50x1=50
