Which obeys the octet rule PF5 Cs2 BBr3 CO3 2-?
Yes, it obeys the octet rule. (Of coarse not an octet for the H atoms: they are saturated with a duplet (=2)). To show you HOW this is done, you will need the structural for… Continue reading
No it is not fully obeying the octet rule. Boron has only 6 electrons (3 own + 3 from each F atom), lacking two for the octet. Fluorine is 3x satisfied, each with 8 electron… Continue reading
Yes it is. It has 10 electrons (five valence electrons from phosphorus and five from five fluorine).
Yes, SO4 2- can be drawn without violating the octet rule. It is also a resonance structure. Here's an illustration below (ignore the dots, it was the only way it posted corre… Continue reading
