Answer:
Coulomb's law, mathematical description of the electric force between charged objects. Formulated by the 18th-century French physicist Charles-Augustin de Coulomb, it is analogous to Isaac Newton's law of gravity.

Answer:
B. Nonpolar covalent bond
Explanation:
Between two Nitrogen atoms, a non-polar covalent bond would be formed.
So, what is the nature of a covalent bond, and what makes a covalent bond non-polar?
A covalent bond is a type of bond that forms between two atoms that shares their valence electrons. The valence electrons are donated by the two atoms and they are shared in order to achieve an octet. This bond type is predominantly between atoms that have an electronegativity difference less than 0.5. Using the electronegativity values, we see that a difference of 0 would be obtained.
Due to equal affinities of the two atoms for the valence electrons, none of them will pull the electrons closer to themselves. There won't be any form of charge separation on the two atoms and a Nitrogen molecule will form. This makes the bond type a non-polar covalent type.
Answer: Some are solid, some are gaseous, a few are liquid. Some are metallic: they have a peculiar lustre; some are coloured (like sulfur) or colourless. Some have a low density; some have a high density. Some are malleable and ductile; some are brittle. Some conduct electricity and heat well; some don’t.
Many metals tend to have structural uses. Nonmetallic elements less so.
Metals tend to have crystal forms featuring close-packed centro-symmetrical structures. Nonmetallic elements tend to have crystal structures featuring more open and directionally packed structures.
Some are especially toxic; some are essential to life; some are both depending on exposure level.
Most are stable; some are less so.
Some elements are highly reactive; some are almost inert (helium, neon, and argon may be completely inert in ambient conditions).
Many metals have basic oxides; quite a few oxides of nonmetallic elements form acids when they are dissolved in water. Some elements can go both ways.
There are many generalisations you can make about metallic and nonmetallic elements, and quite a few exceptions at the margins.
Explanation:
Answer: Solids
Explanation:
In the solid state, the individual particles of a substance are in fixed positions with respect to each other because there is not enough thermal energy to overcome the intermolecular interactions between the particles. As a result, solids have a definite shape and volume.
