How are three isotopes of hydrogen the same? How are they different?

Answer 1

Well, they have the same number of electrons and protons, different number of neutrons, and consequently, different molecular masses as well.

"There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? 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. The atoms of these isotopes have one electron to balance the charge of the one proton. Since chemistry depends on the interactions of protons with electrons, the chemical properties of the isotopes are nearly the same." (excerpt taken verbatim from site listed below)

Answer 2

There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium.
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.

The atoms of these isotopes have one electron to balance the charge of the one proton. Since chemistry depends on the interactions of protons with electrons, the chemical properties of the isotopes are nearly the same.

So the chemical properties such as boiling point, melting point, taste, odour etc are similar. but the only difference is due to the number of neutrons which have no charge but have some wieght, So the 3 isotopes differ in their weights according to the number of neutrons present.

Answer 3

The isotope of hydrogen that we have the most of is just H, a porton with one electron. weight one. The next isotope is often called deuterium, because it weighs 2(one proton and one neutron) the 3rd isotope is often called tritium because it weighs 3(one proton and 2 neutrons) All react the same chemically.The heavier ones are radioactive.They are clear colorless gases.

Answer 4

An atom of each contains one electron and one proton, and they all have the same chemical properties. But ordinary hydrogen has no neutrons in its nucleus. Deuterium has one and tritium has two. Hydrogen and deuterium are stable. Tritium is radioactive with a half life of about 12 years. Deuterium is a little bit heavier than hydrogen, and it has slightly different physical properties; for instance heavy water, D2O boils at about 101 degrees Celsius. But if you drank it, it would have the same effect as ordinary water. Deuterium and tritium are easier to combine in a nuclear fusion reaction than ordinary H.

Answer 5

Same chemical properties; different number of neutrons. In the scientific world, we call these 'isotopes'. Deuterium and Tritium are radioactive, and as a matter of fact are present in certain waters of Long Island.

Answer 6

Hydrogen has one proton and one electron. Deuterium has one proton, one neutron and one electron. Tritium has one proton, 2 neutrons and one electron. Hydrogen in basic terms has 2 isotopes and that they are defined above.

Answer 7

they have the same number of protons (one).
they have different number of neutrons (zero, one, or two).
they may or may not have the same number of electrons (usually one), depending on if the hydrogen is ionized.

Answer 8

They have the same number of electrons, but a different number of nuetrons.

Answer 9

they have the same number of electorns and protons but different number of neutrons
