The mass is made up of protons and neutrons, the valence electrons only determine stability, not mass
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Answer:
Theory
Explanation:
It is a substantiated explanation because of the set of facts and observations on the experiment.
Physics is very common in our lives, and of course this also applies to the performance of a runner.
For example, he or she needs to understand the air resistance when running, they may need to find a way to reduce the most air resistance that is against them so that they can show their best performance.
Or another example is they may need to find out the friction acting on between their feet and the track, they may need to adjust their training in different textures of running tracks, as each acts a different amount of friction.
