Krypton is a cool element, and not only because of its name, although it is a cool name. It is super rare, and is one in a million. To get it, you have to make it cold, so cold that it turns into a liquid, and then, only then, can you obtain it. Now, as you might expect, krypton is not a stable element. Now, you maybe thinking, "So it blows up if you touch it?" No! No, no, no,no, no! All it reacts with is fluorine (another element), and even then all it does is create krypton fluoride. Yes, only krypton fluoride. But something I bet you didn't know about krypton fluoride is that it is used to make lasers! Krypton is in group eighteen and period four, so you can find it on the right side of the periodic table.Krypton is element number thirty-six, so that's how much protons and electrons it has. It also has forty-nine neutrons, and its atomic mass is eighty-five. The word "krypton" comes from the Greek word for hidden, kryptos. The symbol for this fantastic element we know as krypton is Kr, pronounced key-are. Two people named William Ramsay and Morris William Travers were, you guessed it, the people who discovered krypton. Krypton is used in energy-saving lights. Save the energy! Radioactive krypton was used in the Cold War to estimate Soviet nuclear production. Krypton's melting and freezing point are -251.25 degrees Fahrenheit. Its boiling and condensing point is -243.8 degrees Fahrenheit. Yes, krypton is very amazing. I mean, it's three times heavier than air! You're just walking along, then bam! It feels like like you just gained a pound. Guess what? You're in a pocket full of krypton! At 32 degrees Fahrenheit, krypton has a density of 0.049 ounce/gallons.
As you can see, krypton is on the right side of the periodic table.
