abhisar · Answer

Sorry at first i didn't looked it that way

abhisar · Answer

Then it will contain 6 protons and 6 neutrons. This is the nucleus of carbon-12

abhisar · Answer

Got it ?

anonymous · Answer

how so?

abhisar · Answer

Oxygen-16 means Oxygen whose atomic mass is 16

anonymous · Answer

is it because there was the subtraction the element changes?

abhisar · Answer

Atomic mass = No of protons + no of neutrons

anonymous · Answer

oh so the atomic mass changed therefore the element changed

anonymous · Answer

i get it

abhisar · Answer

Oxygen - 16 has 8 protons and 8 neutrons, now if u will remove 2 protons and 2 neutrons 6 neutrons and 6 protons will be left

abhisar · Answer

$\bigstar$ An element is recognised by its atomic number i.e number of protons

@Abhisar when you get a minute, would you mind looking at my problem? Sorry, I wouldn't normally be so rude, but I need it to finish a quiz, and it's quite rare that I find anyone willing to answer questions in Chemistry. Sorry again. :(
