Basic CHM

electrons that participate in chemical bonds, found in the atoms outer most shell.

Region that forms when electrons from different atoms interact with each other.

formed when one atom accepts or donates one or more of its valence electrons to another atom

formed when atoms share valence electrons.

when atoms do not share electrons equally Polar Covalent bond is result

negative electric charge

positive electric charge.

equal in magnitude.

yet opposite in sign, therefore electrically atrracted to each other.

electrically neutral, have no charge and are not electrically attracted to either electrons or protons

Protons and nuetrons.

both much larger in size as well as a mass difference of 1840 times greater then electron.

of atom contains protons and nuetrons. Carries a positive electrical charge.

electrons move around outside the nucleus
