Explanation:
The valency of the element is the measure of the combining power of the element with the other atoms when the element forms compounds or molecules.
<u>Thus, valency has to known to find the how the elements have been combined and how many electrons have been lost, gain or shared.</u>
Given that:
Element A has 3 valence electrons and element B has 2 valence electrons. To find the ionic compound, the valency of the cations and the anions are interchanged and are written in subscripts. Thus,
A B
3 2
Cross multiplying, we get the formula :
<u>Hence, 3 is the subscript for Element B.</u>
Answer to this is O-atom.
Explanation: The Bronsted acid-base theory is the backbone of chemistry. This theory focuses mainly on acids and bases acting as proton donors or proton acceptors.
where is the Lewis Acid and
is the Lewis Base and
is the Covalent Bond.
Reaction of dissociation of in
is given as:
In this reaction O-atom has lone pair in water and therefore it accepts the proton from forming a Lewis Base.
