1. Definition Of Isotope:
Two or more forms of the same element contain equal amounts of protons but different amounts of neutrons.
2. What Does The Number Next To Isotopes Signify?
Atomic mass is the number next to the isotope.
3. How Can You Tell Isotopes Apart?
To tell the difference, isotopes will have different atomic mass than other atoms that make the same element.

shield volcano — a type of volcano built entirely or mostly from fluid lava vents. They are named like this because when viewed from above, you can see just how massive and imposing they are – like a warrior’s shield.</span></span>
Answer:
C. 1 proton 3 neutrons
Explanation:
A nucleus is more stable if the ratio of the neutrons to protons is between 1:1 and 1:1.5.
Thus the ratios of neutrons to protons for the nuclei are as follows
A- 1:1
B- 1:1
C- 1:3
D- 1:2
Among these ratios, C is the greatest thus the nucleus is the least stable.
Answer:
c it does not change the energy state
Explanation:
Concrete is not a compound
