Can u pls explain this?

Simun here total 10 electrons is present... 8 pi electrons from 4 double bonds and there is 2 electrons from negative charge https://youtu.be/1tY6ToTR2rg check this video for con...

it has total 10 electrons. here 4 double bonds so 4×2 = 8 and -2 charge so total electrons will be 8+2= 10. this is an aromatic compound

4pi bonds =8electrons + negative charge (2 electrons) is also delocalisition so total 10 electrons
