The size of an anion Is larger than that of its
Parent atom while that of
cation is smaller than that
of its parant atom
Explain​

Anions have more electrons pulling against the nucleus (the nucleus is losing the tug-of-war), thus making the relative size of the ion larger than the parent atom.

ps. I'm also a bhutanese let's follow each other

my name is pelden lhamo

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
