Final answer:
The assertion that an electron in a silver atom has an average orbital speed of about 1.0 x 10⁸ m/s is false. The orbital speed of electrons is complex in multi-electron atoms and cannot be effectively compared to the simplistic Bohr model, which is best applied to single electron systems like hydrogen.
Step-by-step explanation:
The statement about the average orbital speed of an electron in a silver atom being about 1.0 x 10⁸ m/s is false. In the Bohr model of the atom, which simplifies the mechanics of atomic structure, the electron orbits at discrete orbital speeds which depend on the principal quantum number of the orbit. For hydrogen, the first Bohr orbit for n = 1 has a speed of approximately 2.18 x 10⁶ m/s. The orbital speed for electrons in different atoms will not be the same as for hydrogen, and certainly not as high as 1.0 x 10⁸ m/s due to the larger number of protons affecting the electron's motion.
Considering silver (Ag) specifically, it has 47 electrons, significantly more than hydrogen, and the behavior of these outer electrons is far more complex than can be described by the simple Bohr model. Realistically, the orbital speeds of electrons in atoms like silver are gauged and predicted using more advanced quantum mechanics, which reflects the wave-like nature of electronic motion rather than a fixed circular orbit with a defined speed.
