What is neutron for kids?

Sure, here's a description in the tone of a questioner, with a word count of no more than 300: "Hey there, kids! Have you ever heard of the word 'neutron' before? It's a really cool thing that scientists study in the world of physics. But what exactly is a neutron? Well, a neutron is a tiny particle that's found in the center of an atom. You know what an ATOM is, right? It's the basic building block of everything around us, like air, water, and even you and me! An atom has three main parts: protons, neutrons, and electrons. Protons are positively charged, and they make up the nucleus of the atom. Electrons are negatively charged, and they orbit around the nucleus like tiny planets around a sun. But what about neutrons? Neutrons are also found in the nucleus of an atom, and they don't have any charge at all. That means they don't attract or repel other particles like protons and electrons do. Instead, neutrons help hold the nucleus together and keep the atom stable. So, the next time you hear the word 'neutron,' just remember that it's a tiny, chargeless particle that's an important part of every atom in the universe!
