What is an atom science simple definition?
An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.
How big is the atom Ted Ed?
The answer is much bigger. It is 6.2 billion. That is almost equal to the number of people in the Earth. So if everyone in the Earth owned their own car — and they don’t — (Cars honking) and we put all of those cars into your box …
What does Ted ED stands for?
TED-Ed — TED’s youth and education initiative — aims to spark and celebrate the ideas and knowledge-sharing of teachers and students around the world.
What is an atom kid definition?
The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. They can change and undergo chemical reactions, sharing electrons with other atoms.
What an atom really looks like?
An atom looks like a very small solar system, with the heavy nucleus in the center and the electrons orbiting it. However, the electrons are in layers and can be simultaneously everywhere that quantum allows. Q: Can an atom be seen? Atoms are like extremely small bricks building any material.
How many atoms are in a human?
7,000,000,000,000,000,000,000,000,000
It is hard to grasp just how small the atoms that make up your body are until you take a look at the sheer number of them. An adult is made up of around 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms.
What is the advantage of TED-Ed?

How did Jonathan Bergmann come up with the idea of an atom?
He proposed that there were, in fact, tiny, indivisible pieces of matter that he called “atomos,” meaning “not to be cut.” This idea languished for about 2,000 years until scientists in the 19th and 20thcenturies gathered empirical evidence to support and refine it.
How does an atom bond with another atom?
Let’s Begin… Atoms can (and do) bond constantly; it’s how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond.
When did Democritus propose the concept of Atomos?
More than 2,400 years ago, the Greek philosopher Democritus began thinking about how many times matter could be divided. He proposed that there were, in fact, tiny, indivisible pieces of matter that he called “atomos,” meaning “not to be cut.”
