Which scientist would best describe the motion of the earth

Newton

Explanation:

Ptolemy usually talked about "Earth-centered," or "geocentric" theory that all celestial objects — including the planets, Sun, Moon, and stars — orbited Earth. Earth, in the center of the universe, did not move at all and obviously this theory has been proven wrong.

Brahe model had all the planets (except Earth) orbiting around the Sun, but then the Sun orbited around the Earth. This is also a wrong concept.

Kepler's Laws are mostly based upon the Planetary Motion and are incomplete is some areas.

Only Newton law best describes the motion of all planets where he says that all motion, whether it was the orbit of the Moon around the Earth or an apple falling from a tree, followed the same basic principles.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
