Atoms: Protons, Neutrons, & Other Particles?

In summary, the conversation discusses the concept of atoms and their composition of protons, neutrons, and electrons. It also mentions the existence of other particles such as leptons and hadrons, and how they are produced through high-energy collisions at places like CERN and Fermilab.

Just one quick question I couldn't find an answer on the internet to, after a long search.
We are taught that atoms are made from protons, neutrons and electrons only. There are many other leptons and hadrons existing, but where are they in this story?

Okay, so in a usual atom, only protons, electrons and neutrons exist. But how are those exotics produced?

You smack "normal" particles together with high energies at places like CERN and Fermilab. Some of the energy creates the masses of the "new" particles.

Okay, thanks.
 

What are atoms?

Atoms are the basic building blocks of matter. They are the smallest unit of a chemical element, made up of a nucleus containing protons and neutrons, surrounded by electrons.

What are protons, neutrons, and electrons?

Protons are positively charged particles found in the nucleus of an atom. Neutrons have no charge and are also found in the nucleus. Electrons are negatively charged particles that orbit the nucleus.

How do protons, neutrons, and electrons contribute to the properties of an atom?

The number of protons determines the element's atomic number and therefore its identity. The number of neutrons affects the atom's stability and can vary within the same element, creating isotopes. The electrons are involved in bonding and determine the atom's reactivity.

How are atoms of different elements different from each other?

The number of protons in the nucleus is what distinguishes one element from another. This number is known as the atomic number and is unique to each element. For example, hydrogen has one proton, while carbon has six.

Can atoms be broken down into smaller particles?

Yes, atoms can be broken down into smaller particles called subatomic particles. These include protons, neutrons, and electrons. However, these subatomic particles are fundamental and cannot be broken down further.
