|
Hydrogen 3 has one more electron
|
|
|
hydrogen-3 has two neutrons
|
|
|
hydrogen-2 has three protons
|
|
|
hydrogen-2 does not have protons
|
Detailed explanation-1: -They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. The isotopes of hydrogen have, respectively, mass numbers of one, two, and three. Their nuclear symbols are therefore 1H, 2H, and 3H.
Detailed explanation-2: -Deuterium, or hydrogen-2 (bottom left) has one neutron. Tritium, or hydrogen-3 (bottom right) has two neutrons.
Detailed explanation-3: -Answer and Explanation: The three isotopes of hydrogen are alike because they all have one proton. This is the element’s atomic number.
Detailed explanation-4: -Tritium ( 3H ) It comprises 2 neutrons and 1 proton in its nucleus. Small traces of hydrogen 3 or tritium occurs in nature due to the synergy of cosmic rays with atmospheric gases. They are also released in a small amount at the time of nuclear weapons tests.
Detailed explanation-5: -Hydrogen-4 (atomic mass 4.02643(11)) contains one proton and three neutrons in its nucleus.
