Review :
All atoms contain apositively charged nucleus that has protons t
neutrons .surrounding it are electrons in orbitals freely charged).
Orbitals vary in energy and are arranged in shells .
We only Care about atoms in the first two rows -they contain
and orbitals

Periodic table trend .EN increases up and to the right
Review .An atom always wants astable octet .With anything in them .
always count if an octet is fulfilled
and count the formal charge
