it feels like I am going nuts. I have been told for months that the elements of the second period in the periodic table all HAVE to satisfy the octet rule. What is really driving me crazy is that I've been told numerous times that the number of bonds an atom from the second period is equivalent to: 8 - No. of valence electrons. For Nitrogen that should mean: 8-5=3 bonds max.
How can one explain N2O then? N≡N-O. The Nitrogen in the middle is forming 4 bonds which can not happen by the "formula" I stated above. Is the formula straight up bullcrap or am I overlooking something?
Also, atoms upwards from the third period can contain more than 8 VE. Does that mean they still try to get an octet or are they trying to fill their whole outer shell?
Thanks for anyone who is willing to help.
