for this caution. But a the atomic number off our girl is 18. We can determine the atomic mass was already we have the atomic mass that this 40 Just remember. That atomic number also donates the number off electrons. Hence the number of electrons are equal. Willinto number off Paradorn In every case, the atomic mass off are one is 40 to determine the number off neutron. The formula is atomic mass. My nest. The number of protons that comes out to be 22 for oxygen. The number off neutron Donald Toby eight four for very um, it turned out to be 66 for Nicole. It turns up Toby 30. For Valium, it's 1 24 The atomic number off Tal Uma is 81. The number off neutron can be calculated comes as 1 29 for bar G D. Atomic number off magnesium is 12. We can calculate the number of neutron, its trail sense. It lies and build blue region. Therefore the element of stable, hence magnesium. It's stable. Thus a B, D E on Etch rely in band off stability
