The force of gravity is proportional to 1/r^2, where r is the radius (distance) between the objects.
So if the force was originally
, doubling the distance between them would make the new force
Explanation:
so, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. electronegativity increases as you move from left to right across a period on the periodic table.
