Two Letter Symbol from Periodic Table Rule 12 The Password Game

In our Two Letter Symbol from Periodic Table Rule 12 The Password Game guide, we are going to explain how to solve this part of the game. Obviously, there are a ton of elements whose symbol have two letters, and you can technically use any of them. However, you actually have to be more careful than that, lest you accidentally break one of the other rules. So, what we’ll do is mention which rules that might interfere here, and then list all the elements that break none of them. Let’s begin!

How to Solve The Password Game Rule 12 Two Letter Symbol from the Periodic Table

To solve Rule 12 in The Password Game, which requires you to include a two letter symbol from the periodic table, you can use absolutely any element that uses two letters. That makes it seem pretty easy, but unfortunately, it isn’t. As you’ve probably already gathered, solving one rule can sometimes break a previous one. In this step, we’re mostly concerned about the Roman numerals one. You should avoid any element symbol that includes a capital I, V, X, M, C and D. That still leaves us with plenty of options, of course. However, there’s also the matter of Rule 18, which requires that the total atomic number of all elements you’ve used to equal 200. With that in mind, here’s a list of all the two-letter elements that don’t have any Roman numerals and their respective atomic numbers.
