Is an atom with a nucleus of 31 protons and 31 neutrons a stable isotope?

1 answer:

6 0

<span>No. Since the atom has 31 protons, that means it's an isotope of gallium. Looking up gallium, you can determine that in nature it's composed of the two stable isotopes, gallium-69 and gallium-71, which have 38 and 40 neutrons respectively. Looking further, you will find that gallium-62 has a half life of 116.18 milliseconds which means it's quite unstable.</span>

The price of Guatemala's coffee is higher when compared to the world price of coffee without international trade. It shows that Guatemala doesn't have a comparative advantage in the production of coffee. Guatemala should stop producing coffee and import instead. This would enable Guatemala focus more resocurces on the production of good for which it has comparative advantage.
