Question

Даны нуклиды B 5 11 , Si 14 28 , Mg 12 24, Sn 50 119 определите массовое число нуклидов

Answer 1

Число нуклидов это молярная минус порядковый номер
В = 6
Si = 14
Mg = 12
Sn = 69

Answer 2

Mass Numbers of Nuclides

To determine the mass numbers of the given nuclides, we need to look at the second number in each pair. The mass number represents the total number of protons and neutrons in the nucleus of an atom.

The given nuclides are:

1. B-5-11 2. Si-14-28 3. Mg-12-24 4. Sn-50-119

The mass numbers of these nuclides are:

1. B-11 2. Si-28 3. Mg-24 4. Sn-119
