   What are atoms made of?

   • It includes observations and conclusions that students are meant to make on their own. Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.

   Which atom contains all neutrons and protons?

   • Neutrons are found in all atoms (except for most atoms of hydrogen) and may be found bound together with other neutrons and protons in the atomic nucleus. Since protons and neutrons are so much more massive than electrons, almost all of the mass of an atom comes from the nucleus, which contains all of the neutrons and protons.

   Which particles make up an atom?

   • The last of the three main particles that make up the atom is the neutron. Atoms of all elements (except for most atoms of hydrogen) have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge – they are electrically neutral.

   How many protons and neutrons are in an atom?

   • An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons. The chemical elements are distinguished from each other by the number of protons that are in their atoms. For example, any atom that contains 11 protons is sodium, and any atom that contains 29 protons is copper.

   What is the difference between protons and neutrons?

   • Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force.

   How are protons and neutrons packed together in an atom?

   • The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw pictures of atoms, they show the electrons like satellites spinning round the Earth in orbits.

   Jul 29, 2022 · Atoms of all elements—except for most atoms of hydrogen—have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge—they are electrically neutral. That's why the neutrons in the diagram above are labeled n0. The zero stands for "zero charge".

   Oct 8, 2024 · The protons and neutrons form the atom’s central nucleus. (The ordinary hydrogen atom is an exception; it contains one proton but no neutrons.) As their names suggest, protons have a positive electrical charge , while neutrons are electrically neutral—they carry no charge; overall, then, the nucleus has a positive charge.
