Discrete energy levels (eigenvalues) in atoms (noticed by experiments in spectroscopy) could not be explained by Newtonian Mechanics. Also, the wave-like nature of electrons (eg: diffraction) indicated the first signs of wave-particle duality. These were the first clues.
The principal quantum number is symbolized as "n" in the context of quantum mechanics. It represents the energy level of an electron in an atom and determines the average distance of the electron from the nucleus.
There are various editions and themes of the Clue board game, such as the classic edition, Junior edition, and specialized versions like Harry Potter Clue or The Golden Girls Clue. The number of different kinds varies depending on the specific editions and collaborations released by the manufacturer.
Haven't got a CLUE! :D
Either way would probably be accepted. The "rules" state you must capitalize all parts of a "proper" noun, such as 'Golden Gate Bridge.' Problem is, there is no formal rule on whether a scientific theory is a "proper" noun, particularly when there is no name attached to it. For example, "Maxwell's Equations" would always be capitalized, while "quantum mechanics" is usually un-capitalized. I searched half a dozen sites for an answer to this but found no clue about a rule. So go either way that makes you happy, but (most of all) be consistent.
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.

No clue. Do you mean astronomers? They are scientists working in astronomy.
Scientists can learn many things. They can learn how large a dinosaur was, what it looked like, what it ate, and how it moved, to name a few things.
