3he
Hydrogen has three isotopes with different names: protium (1H), deuterium (2H), and tritium (3H). Each isotope has a different number of neutrons in its nucleus.
H-3 (a more correct writing is 3H) is a radioactive natural isotope of hydrogen, also called tritium. Tritium has in the atomic nucleus 1 proton and 2 neutrons.
Tritium (3H) decays into 3He via beta decay.
Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Carbon has two stable isotopes: carbon-12 (12C) and carbon-13 (13C), along with a radioactive isotope, carbon-14 (14C). Oxygen has three isotopes: oxygen-16 (16O), oxygen-17 (17O), and oxygen-18 (18O).
Hydrogen (H) (Standard atomic mass: 1.00782504(7) u) has three naturally occurring isotopes, denoted 1H, 2H, and 3H. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature.Hydrogen is the only element that has different names for its isotopes in common use today. (During the early study of radioactivity, various heavy radioactive isotopes were given names; but such names are rarely used today). The symbols D and T (instead of 2H and 3H) are sometimes used for deuterium and tritium. IUPAC states that while this use is common it is not preferred.
1H, 2H, and 3H refer to different isotopes of hydrogen, with the number indicating the total number of particles in the nucleus (protons and neutrons). 1H is the most common isotope of hydrogen, consisting of just one proton in its nucleus. 2H is a stable isotope of hydrogen, also known as deuterium, with one proton and one neutron. 3H is a radioactive isotope of hydrogen, also known as tritium, with two neutrons in its nucleus.
simplify both sides of the equation: 1/3h+(-4)(2/3h)+(-4)(-3)=2/3h+-6 ~ distribute that 1/3h+-8/3h+12=2/3h+-6 (1/3h+-8/3h)+(12)=2/3h-6 ~ combine like terms for this -7/3h+12=2/3h-6 -7/3h+12=2/3h-6 subtract 2/3h from both sides: -7/3h+12-_2/3h=_2/3h-6-2/3h -3h+12=6 subtract 12 from both sides: -3h+12-12=-6-12 -3h=-18 divide both sides by -3 -3h/-3=-18/-3 h=6
3h+13 = 7 3h = 7-13 3h = -6 h = -2
The isotope used was thymidine labeled with a radioactive isotope such as tritium (3H) or carbon-14 (14C). Thymidine is a nucleoside that gets incorporated into DNA during the replication process, allowing researchers to track the synthesis of new DNA molecules.

h = -5 8h - 10h = 3h + 25 -2h = 3h + 25 -2h - 3h = 3h - 3h + 25 -5h = 25 h = -5 CHECK: 8(-5) - 10(-5) = 3(-5) + 25 -40 - -50 = -15 + 25 -40 + 50 = 10 10 = 10 CORRECT
8h - 10h = 3h + 25-2h = 3h + 25-5h = 25-h = 5h = -5
The most common isotope of hydrogen is protium, which has one proton and no neutrons in its nucleus. Other isotopes of hydrogen include deuterium, which has one proton and one neutron, and tritium, which has one proton and two neutrons.
each isotope of hydrogen has one proton in its nucleus. The most common hydrogen isotope has no neutrons. It's mass number is one so it would be (1/1H) the second would have one neutron and a mass number of 2 (2/2H) and the third (3/3H)
To simplify the expression (3h - 2(1 + 4h)), first distribute the (-2) across the terms in the parentheses: [ 3h - 2 - 8h. ] Next, combine the like terms (3h) and (-8h): [ (3h - 8h) - 2 = -5h - 2. ] Thus, the expression in standard form is (-5h - 2).
Tritium (3H) decays into 3He via beta decay.
