But sir in the first practice question, you said that valence electron determines The number of bond. ok Does it mean that element that has 7 valence electrons has 7 bonds...??
Atoms or elements like to have a full outer shell of electrons to be stable. Most atoms want 8 electrons in their outer shell (octet rule), but some only need 2 electrons to be in their outer shell to be stable (duplet rule). I believe this part is clear Now let us proceed If an atom has 7 valence electrons based on your question and it is applicable to any element at all, it needs 1 more electron to complete its outer shell. To get that extra electron, it will form 1 bond with another atom. So, an atom with 7 valence electrons typically forms 1 bond to reach a stable configuration. I hope this is clear now?
