Hello everyone so here i would like to represent that the bonding of periodic bonding of period of three oxide because here we need to find out that the we need to compare and contracts the trend in the periodic three dioxide with a chloride and along with that we need to find out of four more different things so let us let us see one by one i would like to make a one table over here in that from that particular table we can easily do the things like this is going to become up over here the formula okay i would like to make so let's let's see this is a morning of the period or three oxidization so we have written over here the formula oxides and oxidation number electrical conductivity of molten state and the structure so for n8 -03 which is in the solid that is having a plus two and because of that this is having the high molten set electrical conductivity is high and this is what a structure of mgo is also this is also oxidation number two and this is also high and because of it i would like to write it over here it is an gained ionic in structure both are the same on next one i would like to write it over al 203 is a plus 3 this is having a plus 4 oxidation plus 5 oxidation and this is plus 3 plus 6 oxidation plus 4 oxidation plus 7 and plus 1 a to that we have written over here the oxidation number now electrical conductivity in the multi -state for the al -2 -0 -3 i would like to write it over here this is what this is also high this is very high this is sorry very low and yeah i would like to write it over here this will be the none it is also no none this is also none and this is uh showing this all three are showing the okay i can write it over here this all three are showing the giant structure okay and this is going to be showing this all two three are showing the molecular equivalent this is a giant this is also the giant's i a covalent is showing structure this is showing a molecular covalent in the very next one we are going to see the bonding of what bonding of a period three oxidation for the same we are going to see our over here we are going to see the formula for the chloride all the things you can see the cl cl cl cl l l l l light chloride chloride chloride chloride chloride so oxidation number we are going to see first of all it's having plus two sorry plus one plus two plus three plus four plus five along with it plus three plus one and this is zero and electrical conductivity in the molten set for the nacl is high this is also high another one is this is elcl 3 is l2 cl6 is poor this is having none none this will be none this is also none and the structure when we are doing going to talk about the niclmgc this is a giant ionic next is molecule this is all showing a molecular covalent structure now next we are going to see about the as we can see the oxides of a chlorovalent structure.

Of the period 3 element and their property which is given in that table the oxidation state of the structure is going to give in the electrical conductivity or due to the free electron due to what free electron in the molten state of what we are going to talking about the molten state that is any then oh it's going to become n a to o okay i can write it over here any an a n2 o m g o al2, o3, nacl, and what mgcl 2, which is having a free electron, free electron, and they are what good conductor.

So this is all about the part one.
04:25
Now moving ahead with the part two.
04:27
So here we what we have to explaining, we need why silicon dioxide is insulin water and we need to describe the acids oxide.
04:36
So i would like to write it over here, the point comparison, or we are.
04:41
We can say the comparing silicon and oxygen they are actually very similar they are similar they are too similar in what in the electronegativity and as i is what covalent coventy bonded to the two oxygen as i is covalently bonded to two oxygen and acidic oxide i can write it over here acidic oxides are oxide that treat or we can say that react with oxygen react with oxygen and it's form what acid that is form our acid and here we are going to be talking about when we are talking about the sio2 that doesn't react actually that was doesn't react with water react with water react with water...
