Disclaimer: I do not own Jimmy Neutron. No way. I'm not a genius.

A/N: Thanks to those who reviewed! This is my first story so I hope it goes well. Yes, this will become a Jimmy/Cindy story.

Sometimes atoms can gain or lose a few neutrons without losing its stability. Yet, there are others that become so unstable that they become a radioactive isotope. For the most part, the world does not need to worry about them because only trace amounts occur naturally on Earth. Yet sometimes the unstable atom can be useful, especially in nuclear reactors. Those that are helpful, though, are made by force.

"And so, because the combination of two different substances, either a mixture or a compound will result." Ms. Killaney taught the class some review work, going over things that they should still know after a week.

Jimmy started to work on some new ideas for inventions in his tablet while Ms. Killaney taught. I cannot believe that Retro High considers this AP Chemistry! Ugh, I could have stayed home today instead of "re-learning" this… But then he caught something that Ms. Killaney said, "…and so milk is actually a mixture as the molecules throughout the entity of the mixture are different."

Jimmy raised his head to look at teacher and coughed lightly. Her attention was then brought to Jimmy who raised one of his eyebrows.

"Oh yes, as James had convinced the whole faculty last term; it is possible to say that milk is a compound, depending on the perspective on view. An example is that by just looking at milk, it looks like a compound. Yet, if you were to place a drop of it under a microscope you could see its inconsistency." The whole class watched this exchange between them with surprise. It's not often that a kid corrects a teacher without even talking.

Jimmy returned to his work, zoning out again. That was neat. I know I'm smart but I don't think that I should have this kind of power over those that are teaching me. It's just wrong. Jimmy shook his head slightly. He looked around the room. Considering that this was AP Chems, there were only thirteen kids here but most of them were seniors. Jimmy was the youngest there.

The students don't even argue! They just sit down in their chairs and pretend to listen while the teacher is speaking. Why doesn't someone even try to answer the questions Ms. Killaney asks? Then again I shouldn't talk; I don't answer questions that have an obvious answer either. At least not since I actually had another competetor. He gave a small snigger which drew the attention of the guy sitting next to him.

"James, you off on your own planet again?"

"Huh? Oh, no, I was just pondering about the whole class/teacher interactions."

"I've gotta say James, you're in a class of your own." He looked at Jimmy's note book. "Other students are drawing in their notebooks to distract themselves from learning and here you're drawing things we can't even comprehend."

"It's just some adjustment that I'm thinking of doing on some inventions." He just watched as the dark haired, green eyed guy flip through his book, making sure that he wasn't delving to deep.

He looked up from Jimmy's notebook. "So, you still meeting with us at the University?"

"Sure. I wouldn't miss it!" Excitedly, he went on about their visit. "A lecture on the thermodynamic effects on the universe with every little-"

"Whoa, James, slow down! I know that you're excited, but come on you know that we're not gonna understand anything the lecturer says." He just looked at Jimmy with wide eyes at his excitement.

"I know, Robbie." Jimmy smiled at him. "And you don't know how much it means to me that you guys are coming with me even if you hate science."

"Aw, bro, don't mention it. You've always had our backs."

Ms. Killaney gave the boys a look of irritation. "Guys, settle down. I know you guys know this, but at least let the others learn a little."

And with that, they returned to face the front, or in Jimmy's case his notebook. I'm glad I have at least one friend in this class. It sucks when I don't know anyone else really well in class. He chuckled. I remember in elementary when I always knew everyone in class. Especially fifth grade though. That was the first year that I knew the most people personally. Most of all were Carl, Sheen, even Libby and Cindy. I still remember when we finally got over ourselves and acted like friends... orstarted to realize that together we had a lot of potential to be friends...
