Which American astronomer in 1905 predicted the existence of Pluto?
It was Lowell
Astronomers predicted its existence by observing the effects of its gravity.?
Neptune
What two heavenly bodies which were predicted to exist before they were sighted are?
Neptune and Pluto are two heavenly bodies that were predicted to exist before they were sighted. Neptune's existence was predicted based on perturbations in the orbit of Uranus, while Pluto's existence was predicted based on gravitational influences on the orbits of Neptune and Uranus.
What did Mendeleev predict about the periodic table?
Dmitri Mendeleev predicted the existence and properties of several elements that were later discovered and filled gaps in the periodic table. He also predicted the properties of these elements based on their position in the periodic table.
Astronomers predicted the existence and orbit of Neptune based on?
Astronomers predicted the existence and orbit of Neptune based on discrepancies in the orbit of Uranus. These discrepancies suggested the gravitational influence of another planet beyond Uranus, leading to the discovery of Neptune in 1846.

Who discovered or first identified the neon atom?
Neon was first predicted byWilliam Ramsay. It was first discovered and isolated byWilliam Ramsay & Morris Travers.
Who predicted the exist of electromagnetic wave and who proved it?
James Clerk Maxwell first theoretically predicted the existence of electromagnetic waves, however David Edward Hughes is partially credited as he made the first successful radio transmission. Heinrich Hertz is the man who actually proved Maxwell's theory of the existence of electromagnetic waves.
How is molecular geometry predicted?
it may be predicted either by no of electrons around the central atom of the molecule or by type of hybridization process of orbirals of central atom....

Who came up with the element Oxygen?
Mendeleev (or at least predicted its existence)
Who predicted that the existence of several missing elements?
You think probable to Dimitri Mendeleev.
What overall change does an atom have?
Dalton predicted that the atom of any element are different from the atoms of all other elements.
When was hafnium discovered?
Hafnium was discovered in 1923 by Dirk Coster and George Charles von Hevesey. Niels Bohr however was the first scientist who predicted its existence. Hope that helps!
What is the subatomic particle known as the maon and who predicted its existence. I'm absolutely sure that it is maon.?
Perhaps you meant the meson. Mesons are composed of two quarks, a quark and its antiquark. I'm not sure who predicted them but I believe the pi-meson was the first discovered. Then suddenly many more were discovered that were not predicted and they didn't know what to do until the current Standard Model was developed.
