Have both odd Z and N
There is no stable nuclide with???

2 answers

Answer 22

A=5 or A = 8, stable nuclides

Question 23

The ratio N/Z increases gradually with A because of the increasing influence
of the electrical repulsion of the protons.

Answer 23

just understand it

Question 24

refers to types of electromagnetic radiation that do not carry enough energy to ionize atoms or molecules, meaning they cannot
