Answer:
It's C
Protons repel the neutrons.
Explanation:
An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. The instability of an atom's nucleus may result from an excess of either neutrons or protons.
Answer:
Different types of isotopes are used for different materials or objects. For radiometric dating, uranium-235 is considered best for it while carbon-14 is used for dating of rocks. It is also used for dating of wood samples.
Explanation:
Carbon-14 and uranium-235 are used for different materials or objects for measuring the age of these materials. These two isotopes are radioactive in nature which means they emit gamma radiations which allow us to find the age of different objects. Carbon-14 has a low half life so it can be used for those objects which are present before thousands of years while uranium-235 is used for materials which are millions of years old due to high half life.
Since it has lost 2 electrons, hence the protons would be more by 2.
