Octet rule - Study guides, Class notes & Summaries

Gaining vs. Losing electrons - ️️N+1 = Losing electron N-1 = Gaining electron Electrons = electronegative Octet rule - ️️Atoms are most stable when their outer shell is full. The outer shell has to be filled with 8 electrons EXCEPT Hydrogen and Helium with just 2 electrons. Three Physical States of Matter - ️️Solid, liquid, gas Element - ️️Substance that cannot be broken down into other substances by chemical reactions Matter - ️️Anything that occupies space and has a...
