Now the group through a elements are not as reactive with water like group 1A and 2A. In fact, we're going to say that the boron family metals do not react with water, but they do react with steam. So water has to be in a more volatile energetic state for the metals to pay any attention to that to it.

So if we take a look, we're going to say that we have our group 3A medals represented by M here, with thallium being outside of it. Remember here group 7-8 we don't even worry about this because it's radioactive. Now why is thallium different from the others? Well, we know that thallium is a group 3A and the predominant charge tends to be +3, but not when it comes to thallium. Thallium actually prefers having a plus one charge or plus one oxidation state. This makes it react differently as well as other things that are outside the scope of this course that cause it to react differently than the other group 3A metals.

Now for the group 3A medals, they react with gaseous water or steam. They're going to produce the ion form of themselves. They're in Group 3, so they're three plus we're going to produce hydroxide ion and H₂ gas. Balancing this out, we'd have a 2 here, a six here, A2 here, a six year, and a three here. Again, balancing is not what's important here. What's important is that these elements in Group three are less reactive with water, so you need to have it in in steam form. And then what's important is the charge of the majority of the group, 38 elements being plus three as a product and us producing hydroxide ion and gaseous hydrogen gas.

Now thallium reacts with water but a little bit differently. Remember thallium, it's predominant charges plus one. It would also produce hydroxide ion in H₂ gas. Balancing this out, we'd get 22, 2, two and one. So these will represent our different types of balanced reaction when different metals from group 3A react with steam.
