"hello everyone welcome to lito this is priya and here we have a question about isotopes of hydrogen so let us look into the question for the symbol of hydrogen t h d and t tabulate three subatomic particles found in each of them so these h d and t are the isotopes which means they have same atomic number but their number of neutrons will be different in that atoms so let us look into the symbol of these h d p h means hydrogen d means deuterium and t means tritium and the symbol of hydrogen is h symbol of deuterium is b and symbol of tritium is t and mass of these three isotopes are one two and three and atomic atomic number of these atoms are 1 1 1 so number of electrons present in these atoms are also 1 1 1 and number of protons present in these atoms are again one one and one but there will be only change in the number of neutrons so the number of neutron is zero one and two because of this the mass of these three isotopes have changed hydrogen is fun deuterium is two and tritium is three because they have different number of neutrons and their mass has changed so this is about the subatomic particles present in hdnt hope you understand this video if you like my video please subscribe to our little channel and if you have any doubts you can leave a message in comment box thank you"
