Question

Chemistry question!

Answer 1

I was sorry it was my duty... Anyways isotopes of an element always have same atomic no.. Hence same no. Of protons... But they have different mass and hence their no. Of neutrons will be different

Answer 2

In simpler words... Isotopes are those elements which have same atomic number and different atomic mass

Answer 3

Hmm so that would mean the same element to

Answer 4

because wouldnt the different number be an electron

Answer 5

So ur saying that the no. Of electrons also differ?

Answer 6

no. I saying I thought that Isotopes of the same element differ in the number of electrons

Answer 7

We take a case of neutral atom here... The no. If protons is equal to the no of electrons. I'm reminding u once more.... Neutral atom

Answer 8

So only the no. Of neurons differ right?

Answer 9

Okai let's take 2 isotopes of carbon \[C ^{14}_{6} and C ^{12}_{6}\] So here we can see the atomic number remains same. That is 6! Atomic number shows us the no. of electrons or protons right?
But we can see the atomic mass is different ! atomic muss contains the summation of both neutrons and protons. We know no. of protons and electrons in both isotopes are the same ! Then the difference in atomic mass is due to the change in no . of neurons right ?

Answer 10

oh ok so yes because of there numbers

Answer 11

Mass* Neutrons*

Answer 12

Exactly! I hope now you've understood it :)

Answer 13

Good work with the example Rush :)

Answer 14
