Re: Radius
The higher the electronegativity, the smaller the atomic radius. This is due to the electrons being closer to the nucleus, thus causing the atomic radius to be higher.

Each of the bonds determine the shape that will be used. Based on the number, you have to pick a shape.

Re: Isotopes [ENDORSED]
This means that the element does not have the same amount of neutrons in the nucleus but does have the same number of protons. This causes the molar mass of an element to vary because the molar mass depends on the sum of the neutrons (which vary) and the protons.

Re: Law of Conservation of Mass [ENDORSED]
The Law of conservation of Mass means that the mass of an equation can not be created or destroyed. Therefore, the mass in the reactants (left side) should be the same as the mass in the products (right side).
