Nitra

She walked to the ChemQuest academy. She was twenty-two years old. Beaker asked her a question. "What is nitrogen?" Nitra answered him. "I am slow to bond. I have three empty spots. But the air's N₂ is a triple bond. It is very strong. It takes lightning or bacteria or factory heat to break us apart. Once broken and re-bonded, I lock in deeply. I join with hydrogen to make NH₃. Or with carbon to make proteins, DNA, and amino acids. That's why proteins and DNA are stable. I am slow to warm. But I am strong when bonded." Beaker just nodded. "You are appointed," he said.

In her workshop, Nitra starts every first lesson the same way. She settles onto the workbench. She moves slowly. She takes her time. She always takes a moment. She shows off her three-stripe chest-band. She says, "I am Nitra. I teach the chemistry of nitrogen. Nitrogen is slow to bond, strong when bonded. My three stripes mean three bond-points. I am 78% of the air you breathe. I am in almost every protein in your body. I am in every DNA base. Once I'm in, I stay."

She teaches how nitrogen builds things: Nitrogen makes three bonds. Sometimes three single bonds, like in ammonia (NH₃). Sometimes one triple bond, like in the air (N₂). It can make other kinds too. N₂ is 78% of the air. That's most of the air you breathe. It doesn't react much. This is because of its super strong triple bond. That's why the air doesn't just catch fire. N₂ doesn't join in easily. Something has to break N₂ apart. We call this 'nitrogen fixation.' Lightning does it. Special bacteria in plant roots do it. Big factories do it to make fertilizer. Breaking N₂ always takes a lot of energy. But once it's broken, plants can use it. Nitrogen plus hydrogen makes ammonia (NH₃). Ammonia is in fertilizer. It's in some cleaning stuff. Plants use it to build amino acids. Nitrogen, carbon, hydrogen, and oxygen make amino acids. Your body has 20 kinds of amino acids. All of them have nitrogen. Amino acids are the building blocks for proteins. Amino acids link up to make proteins. They connect with special C-N bonds. Proteins are long chains. They do everything in your body. They build things. They help things happen. They carry stuff. They send messages. DNA bases have nitrogen. Adenine, guanine, cytosine, thymine. These are the letters of your DNA code. They all have rings full of nitrogen. Two DNA strands stick together. They use hydrogen-bonds. Whisperer teaches about those. These bonds are between the nitrogen-filled bases. Don't just think of it as a personality. Nitrogen is slow to warm because of its strong triple-bond energy. Its loyalty is the strength of its C-N bonds in proteins. The way atoms act is its personality.
