Hello everyone today. We are being given the falling problem. Consider the following illustrations in which protons are shown as pink spheres and neutrons are shown as green spheres, identify the illustrations that depict isotopes of the same elements and identify the illustration that depicts a completely different element. So we are given these three diagrams and we are to determine which one which two of these are isotopes and which of them is a different element. So the first thing I wanna do is you want to define an isotope which in simple terms is the is an element with the same number of protons but different number of neutrons. So the only thing changing in an isotope is the number of neutrons. And so we said that pink represents protons and green represents neutrons. Right? So pink represents our protons and green represents our neutrons. So we can begin to answer the question. The first sphere has three pink and three green. The second has three pink but four green. So we said that isotope has the same number of protons. Which one in three do. They both have three protons but they differ in the number of neutrons. The first one has three spheres that are neutrons. And the second sphere has four neutrons. And so we can go ahead and say that one and two are isotopes. And so that's actually going to lead us to our answer being Andrew choice A that one and two are isotopes and three is a completely different element. So why is three completely different element? Well, if we look at three there are two protons and three neutrons very different. The number of neutrons is differing, as well as the number of protons. So in our first fear, we had three protons and three neutrons and our second sphere we had three protons, but four neutrons. And since we decided, and since the number of protons changed completely in the third sphere, that made it a completely different element. And with that we've answered our question overall, I hope this helped, and until next time.
