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.
12 protons
13 neutrons
12 electrons
An isotope is an atom with a different number of neutrons but same number of protons
It is a global issue that is impacting WA’s water supply and our way of life. The impacts are felt across the world, Australia, and throughout WA in our communities, businesses, farms and homes.

The number of protons in an atom of krypton is 36.
<u>Explanation:</u>
The number written above the symbol of Kr in the periodic table represents the atomic number of the element . Then the number written in the below represents the mass number.
So the mass number of krypton is 84 and the atomic number of krypton is 36. As it is known that number of protons and electrons will be equal in a stable element. Thus, the krypton atom will be having 36 protons.
