Hi Sorry for late reply
Aditi H is atom and do not exist as it is very reactive. H is always H₂ in reactions like O is O₂ ,Cl is Cl₂ .K is very reactive and displaces H from water as H₂ gas. You need to balance the equation also.
2K(s) + H₂O (l) ---> K₂O + H₂

I did a seperate page,  but here is the question

its not letting me upload the question

I'm very confused about this question, first, why did the answer have H2 on the product side? I thought H+ ions were forming on the product side, not H2 gas? It also says 'aqueous,' which means it's in water. So, wouldn't the balanced chemical equation be, K (s) + H20 (L) ----> KOH (aq) + H+ (L)? I'm confused about how they obtained the gaseous H2. 

I'm still confused, slightly

As we move down the group size increases and acidity also increases because it is easy to break the bond of H .Big bonds are weak bonds.Hence H₂Po is stronger than H₂Te.
However we know that Po is a rare and radioactive element.

because as you go down the group size increases? So that would mean Po would be the biggest in size and be the weakest Bronsted acid?

wait a second, i am still confused. What about Po? Polorium  is the biggest in size, so isn't that the weakest?

Ohhh! So basically, a Bronsted acid releases a hydrogen ion! Oh, and then that also means we are looking at the strongest bonds because of the difficulty in breaking the bond with hydrogen. Okayy. Makes sense, thank you!

Think in terms of s,p,d and f orbitals and you will get more clear picture.
