True or False: Electrons can exist in multiple orbits around the nucleus simultaneously.

The statement that "electrons can exist in multiple orbits around the nucleus simultaneously" is false because, in classical atomic theory and quantum mechanics, electrons occupy specific energy levels or orbitals rather than multiple at the same time. Each electron is situated in a distinct orbital that corresponds to a certain energy state.

According to quantum mechanics, electrons are described by wave functions, which dictate the probability of finding an electron in a particular location around the nucleus. While it's possible for electrons to transition between orbitals when they gain or lose energy, they cannot reside in more than one orbit at the same time. This principle underlies many important concepts in chemistry and physics, including the arrangement of electrons in atoms and the behavior of matter at the atomic level.

The idea of simultaneous existence in multiple orbits might confuse the concept of superposition in quantum mechanics, which refers to the ability of particles to exist in multiple states; however, for electrons in an atom, each electron occupies a defined orbital without sharing space with another electron in multiple distinct orbitals. Thus, the answer is indeed false.
