Which of the following statements about planetary motion is false? A. Each planet would move in a straight line without the Sun's gravitational pull. B. Each planet has a period of revolution
and a period of rotation. C. Each planet moves in a circular orbit around the Sun. D. A planet's speed changes as it orbits the Sun.
The FALSE statement about Planetary Motion is: Each planet would move in a straight line without the Sun's gravitational pull. ***The sun's gravitational force is very strong. [ If it were not, a planet would move in a straight line out into space forever. The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving
in an orbit around the sun. ]

The number of valence electrons in an atom can often be quickly determined by referencing A. the atomic number of the element. B. the period number on the periodic table. C. the group number on the periodic table. D. the atomic mass of the element.
Weegy: The number of valence electrons in an atom can often be quickly determined by referencing C. [ the group number on the periodic table. The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized. With the exception of groups 3–12 (the transition metals), the number within the unit's place identifies how many valence electrons may be associated with a neutral atom of an element listed under that particular column. ] User: Which of the following men did not help to advance the understanding of the atom?
