Nucleus: Common Terms
A technique called mass spectrometry is used to segregate different isotopes of an element. In such a setup, hydrogen gas is sent which is ionized by the ion source and we get nuclei of protium (11H), deuterium (21H) and tritium (31H).
A perpendicular magnetic field is used to deviate these in separate beams. Pick the correct option.
a - protium; b - deuterium; c - tritium
a - protium; b - tritium; c - deuterium
a - tritium; b - deuterium; c - protium
a - deuterium; b - protium; c - tritium
Nuclei with same number of protons but different number of neutrons are called
Nuclei with same number of neutrons but different atomic number are called
Nuclei with same mass number are called

I and II are isotopes
II and III are isobars
II and IV are isotones

Depends on the allotrope, whether it is graphite, charcoal or diamond.

The future you synthesizes a new element. A neutral atom of the element, say 'X', has 4 electrons and 2 neutrons. How will you represent the nucleus of the element in your award winning paper?

The chemical behaviour of an atom depends upon
the number of protons in its nucleus
the number of neutrons in its nucleus
the number of electrons orbiting around its nucleus
the number of nucleons in its nucleus.
