Question

what is the valency of potassium and ozone.​

Answer 1

$<b>hlo frnd here is ur answer$

valency of potassium is +1

valency of ozone is +3

hope helps mark as brainliest plz

Answer 2

Hello your answer...

If the last number is equal or less than 4 than the valency is equal to that number but if the last number is bigger than 4 then we have to subtract that number by8

let us find the valence electron of potassium so we need atomic number and electronic configuration..

1)Patassium
Atomic no.=19
So electronic configuration is2,8,8,1
last number is 1 so the valency of potassium is 1

2)Ozone

it has3 valencies that is 3,2,1 because its structure is 0-0=0

The valency of Ozone is 3 because the central atom makes 3bond...

Thanks..

hopr it helps u
