Sodium (Na) and iodine gas (I2) react to form sodium iodine (NaI). Which equation is a correct representation of the balanced equation?
2Na+I2→2NaI
I2→2NaI+2Na
Na→NaI+I2
NaI→2Na+I2

give me abc and i will get it for u.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.

level 4 to level 2 : ))
