Explain why Chemistry is an awesome class

:)

300
An atom or group of atoms that has gained or lost one or more electrons, thus acquiring a charge.
What is an ion?
300

Covalent bonds form between these types of elements

What are nonmetals?

300
A covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive.
What is a polar covalent bond?

A type of weak chemical bond formed when the partially positive hydrogen atom participating in a polar covalent bond in one molecule is attracted to the partially negative atom participating in a polar covalent bond in another molecule.
What is a hydrogen bond?
400
The attraction of a given atom for the electrons of a covalent bond.
What is electronegativity?
400
