How did deuterium and tritium get to be named 2 of hydrogens' isotopes?

Because H-1 is also called protium, H-2 is called deuterium and H-3 is called tritium.
The number of protons is identical in all hydrogen isotopes and is equal to 1; only the number of neutrons is different.

What are some charicteristics and properties of the element hydrogen?
So named as the 'water maker'. Hydro - gen. Deuterium is a hydrogen atom with an extra neutron added to the nucleus. And Tritium, with two extra neutrons added.Tritium is unstable with a half-life of 12.33 years. Use in 'Indiglo' watches.
Why deuterium is heavy hydrogen?
Deuterium is named from the Greek, with deuterios meaning 'second'. This refers to the second particle in the nucleus, a neutron. There is a H variant called Tritium, which contains two neutrons in the nucleus. Plain hydrogen is also called (but rarely) protium. Hydrogen means 'water generator'.
How are isotopes of the same element named?
The same name with a different atomic mass number. As an example U235 and U238 are two isotopes of Uranium
What are the three major subatomic particles in an atom?
The three major sub-atomic particles are : - PROTONS, ELECTRONS and NEUTRONS. Protons are positively charged (+) and found in the nucleus of an atom. Electrons are negatively charged (-) and found around (not IN) the nucleus of an atom. Neutrons have no charge (o) and are found in the nucleus of an atom . The number of protons ( and electrons) is the ATOMIC NUMBER, and the atoms position in the Periodic Table . The number of protons equals the number of electrons ( in order to keep the charges balanced). The Sum total of the protons and neutrons is the ATOMIC MASS/WEIGHT. The number of neutrons can vary This gives a different atomic mass for a given element and are known as ISOTOPES. Taking hydrogen as an example It has three isotopes. [1/1]H (Protium) ; 1 proton . ZERO(NO) neutrons, 1 electron. [2/1]H (deuterium); 1 proton , 1 neutron , 1 electron [3/1]H (tritium); 1 proton, 2 neutrons, 1 electron . (This isotope is radio-active) [1/1] protium is the most common isotope of hydrogen , and what is normally thought of as hydrogen. [2/1] deuterium is sometimes named as 'heavy hydrogen'. It is not a very common isotope. [3/1] tritium is sometimes named as 'super-heavy hydrogen'. It is a rare isotope ,and because of its radio-activity only found in labs. However, as mentioned above for all isotopes the protons and neutrons are in the nucleus of the atom, and collectively they are named as 'nucleons'. The electrons are found outside the nucleus. These 'rules' apply to all elements.
What is the name of a carbon isotopes that has a mass number of 12?
The isotope is named "carbon-12".
What is the difference between mendelevium-256 and mendelevium-258?
They are the isotopes. Because of the difference in the number of neutrons by 2 they have been named that way.
A compound consisting of Br and CD ions would be named?
There are many: for example, bromoform-d (CDBr3), in which a deuterium atom replaces a hydrogen atom. Other methane-based compounds are dibromomethane-d 2 (CD2Br2) and tribromomethane-d 3 (CD3Br). There are many more organic compounds in which hydrogen atoms are replaced by deuterium atoms.
How is an isotope and mass number related?
It isn't, as such. Isotopes of the same element have different numbers of neutrons, and neutrons have a mas of one atomic mass unit (amu). So isotopes have different atomic masses, but being told the number of neutrons any isotope has, will not enable you to say what element or atomic mass it had, unless you remembered the details for every single isotope. Even then different elements can have the same number of neutrons. Isotopes do get named after their atomic mass however - uranaium 235 has an atomic mass of 235, for instance.
What stable isotopes are used in labeling peptides?
Stable isotopes used in labeling peptides may include 2H, 15N & 13C, respectively, or a combination of 15N & 13C.Source: a passage named Stable Isotope Labeled Peptideson the website of Creative Peptides.
Can elements be represented by symbols?
YES!!! Take a look at the Periodic Table. All the named elements are there , together with their elemental symbol and other data. Some elements have a sub-symbol to represent an isotope of that element. Taking hydrogen Symbol ; H However its isotopes are sometimes represented by p ; (protium) for [1/1]H d( or D) ; (deuterium) for [2/1]H t( or T) ; (tritium) for [3/1]H
What is the h-bomb made of?
Hydrogen bombs, or H-bombs, never were used in World War II, even though the idea for them was introduced before 1940 [source: CBS News]. Hydrogen bombs use the process of nuclear fusion -- or fusing instead of splitting nuclei -- to create enormous amounts of heat and radiation explosively. The process of fusion requires that hydrogen isotopes be squeezed together under high temperatures and pressures to fuse into helium, which releases heat, neutrons and energy. There are some challenges to creating fusion in a bomb. First, the hydrogen isotopes deuterium and tritium are gases, which are hard to store. Bomb makers instead use solid lithium-deuterate because it is easy to store, does not radioactively decay at room temperature and can produce both deuterium and tritium under high temperatures and pressures. Second, the bomb must have high temperatures and pressures for fusion to occur; this requires a fission reaction. A hydrogen bomb is essentially two types of bombs -- an implosion-type fission bomb and a fusion bomb -- in one casing. This design is named a Teller-Ulam bomb after the designers, Edward Teller and Stanislaw Ulam. The major inside components are: Fission bomb -- a sphere containing a uranium-235/plutonium-239 core (fissionable material), enveloped by a uranium-238 tamper that is surrounded by chemical explosives. A tamper makes a fission process more efficient by expanding when heated and exerting pressure on the fission process. It also reflects neutrons back into the fission process. Fusion bomb -- cylinder with a core rod of plutonium-239 surrounded by lithium-deuterate fuel and a uranium-238 tamper Polystyrene foam -- fills the empty space in the casing The explosives in the fission bomb go off, which compresses the fission fuel and initiates fission. Fission produces high heat, X-rays and neutrons. The X-rays heat the foam and tamper around the fusion bomb. The heated tamper and X-rays exert high pressure and temperatures on the fusion capsule, which squeezes the fuel and initiates fission in the plutonium rod. The neutrons from the fission of the rod combine with the lithium-deuterate to produce tritium and deuterium. The high temperatures and pressures cause the deuterium and tritium to fuse, which produces helium, high heat, X-rays and neutrons. The bomb explodes and releases heat, X-rays and neutrons. All of these events occur in just billionths of a second and release 700 times more energy than the atomic bombs dropped on Hiroshima and Nagasaki, Japan. -Craig C. Freudenrich-
Where was the first enriched uranium made for the Manhattan Project?
The first separation of uranium isotopes was in 1942 in USA - electromagnetic separation (the installation was named calutron).
