Given :
An atom Iodine.
To Find :
How many electrons will an iodine atom donate or accept, based on its number of valence electrons :
A.donate seven electrons
B.accept one electron
C.donate one electron
D.accept seven electrons
Solution :
We know, valence electron in Iodine is 7 electrons.
So, it is easy for iodine to accept 1 electron rather than giving all 7 electrons to another element.
Therefore, Iodine will accept one electron ( Option B.).
Hence, this is the required solution.
