The scientist which was credited with first stating that electrons orbit an atomic nucleus was Niels Henrik David Bohr. He was the proponent of the Bohr model of the atom, wherein he states that energy level of electrons are distinct and that electrons revolve on stable orbits within the atomic nucleus but can actually transfer from one orbit (level) to another. The orbitals are called: s, p, d and f orbitals.

Breaking glass is an example of a physical change because if you break it, it is still glass.
A dipeptide is formed by the process of dehydration synthesis, which in this case allows two amino acids to come together and form a larger molecule plus water.
Explanation:
Certain materials, called conductors, allow electric charge to move pretty freely through them. ... Other materials, like plastic and rubber, are called insulators because they don't allow electric charges to move through them.
