Okay kiddo, let's talk about the lithium atom! Atoms are tiny particles that make up everything around us, like rocks, air, and even you and me!
The lithium atom is special because it has three parts: protons, neutrons, and electrons. Protons and neutrons live in the middle of the atom, called the nucleus. Think of it like the center of a ball. The electrons whizz around the nucleus like little bumblebees buzzing around a flower garden.
The lithium atom specifically has three protons and four neutrons in its nucleus. That's why its number on the periodic table is 3! It also has three electrons that zoom around the nucleus.
One cool thing about lithium is that it's a metal, which means it's really good at conducting electricity. It's also known for being a lightweight and soft metal.
I hope that makes sense, kiddo! If you have any more questions about the lithium atom, feel free to ask!
