unable to understand the question

Answer 2

Answer:

I don't believe there is any simple way to determine what they are except by just plain memorization. I have given some tricks below that have helped me.

When I write down my poly-atomic ions, I generally put them in similar groups in a certain order. From least amount of oxygen to most amount oxygen.

hypo (name of ion) ite -> least oxygen

(name of ion) ite -> one more oxygen than above

(name of ion) ate -> one more oxygen than 'ite'

per (name of ion) ate -> one more oxygen than 'ate'

Understanding the above helps most with 'ite' and 'ate'. 'Ate' generally being 1 more than 'ite' for oxygen.

Then I list them from least charge to most charge. I order them this way:

Nitr ite NO2−

Nitr ate NO3−

Sulf ite SO32−

Sulf ate SO42−

You can see that 'ate' has one more oxygen, and that I have listed them in charge order. Sometimes looking at the trends in oxygen and charge will help you memorize. I have had to remember them by writing them down several times and now I am comfortable.

pls mark me as a brainliest
