Tell students that hydrogen is the simplest atom. It has only 1 proton, 1 electron, and 0 neutrons. It is the only atom that does not have any neutrons. Explain that this is a simple model that shows ...

Explore the fundamental components of an atom: protons, neutrons, and electrons. This video discusses why the traditional model of the atom is inaccurate, highlighting the unpredictable nature of ...

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 meter. This video also goes the basic parts of an atom (protons, neutrons, and electrons) and why the ...

Save guides, add subjects and pick up where you left off with your BBC account. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It ...

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...

Students will learn about the different particles that make up an atom. Students will understand that the mass of an atom is determined by the number of protons and neutrons in that atom's nucleus.

The collisions will happen under enough heat and pressure to melt protons and neutrons and release their components (quarks ...

The number of protons is what defines the element. Oxygen, for example, has eight protons. However, the number of neutrons in an atom can vary, leading to different forms of elements, called isotopes.
