The picture of correct answer is attached it is the second one from the left since it has 5 electrons in outermost shell so it can share 3 electrons to complete the octet rule, while first one contains only one electron in outermost shell so it easier to be lost, third one has 8 electrons so it has complete valence shell and last one with only two electrons in outermost shell so it is easier to lose these two electrons.
from 5 to 7 electrons on outermost shell can form covalent bond
from 5 to 7 electrons on outermost shell can form covalent bond
is the product of a reaction between a strong acid and a sulfite ion (which acts as a base).
A chemical reaction in which an acid and a base interact quantitatively is known as neutralisation or neutralisation. By neutralising a reaction in water, surplus hydrogen or hydroxide ions are removed from the solution.
Despite being a weak base, the sulfite ion can hydrolyze to form basic solutions. The equilibria in an acidic solution are changed to create sulphurous acid, which leads to the development of SO2 gas. A colourless gas with a distinctive suffocating smell, sulphur dioxide.
The reaction mechanism is as follows;
