Question

the element with atomic number 9 can exhibit oxidation State of
a +1
b +3
c -1
d +5​

Answer 1

Answer:

option number b is A correct na

Answer 2

Answer:
OPTION (C). -1 is the correct answer.
Explanation:
Atomic number of the element = 9
Electronic configuration= 1s2 2s2 2p5
p orbital of the given element contains 5 electrons
Maximum number of electrons filled in p orbital is 6
hence it acquires an electron from the other element to complete it's octet.
Therefore. it acquires -1 charge.
So OPTION C Is the correct option.
