why all the elements has the same mass as 22.4 dm3 ,while all the elements have different atomic masses? So why the volume increases with the increase in mass and the increase of energy levels? please answer fastly tomorrow is my exam and please explain the answer.
Answers
Firstly, all the elements has not the mass of 22.414dm3. Rather they have same volume that is 22.414dm3. And reason is that they all have same no of particles that is equals to 6.o2 * 10^-23 .......
Secondly, they all have different masses because atmic mass is the sum of protons and neutrons. And all elements have different no of protons, even same element have different no of neutron giving difference in the atomic mass of same element. (that we called as isotope).
Thirdly, with the increase in atomic no, there is an increase in no of electrons and protons. so no of shells increases to accomodate these increasing no of elestrons.
HOPE YOU UNDERSTND AND IT HELPS YOU.
plz mark as BRAINLIEST if you yhink i deserve it.
and ask me about this if you dont understand.
I'll tell you:)
