Question

Indicate how the atomic number and the mass number of an isotope will change when it’s nucleus loses

i.An alpha particle
ii.A beta particle
iii.gamma rays
iv. A neutron

Answer 1

Answer:The mass number of an isotope is the total number of protons and neutrons in an atomic nucleus. If you know that a nucleus has 6 protons and 6 neutrons, then its mass number is 12. If the nucleus has 6 protons and 7 neutrons, then its mass number is 13. The symbol for an isotope lists the mass number as a superscript at the upper left.
