Explanation / Answer
answers : matching
Si --------------->4
O -----------------> 6
Br -----------------> 7
P ----------------> 5
Se --------------> 6
explanation:
number of valence electrons = group number
Si ---------------> 4th group and its valence = 4
O,Se -----------> 6th group and its valence = 6
Br --------------> 7th group and its valence = 6
P --------------> 5 th group and its valence = 6
