Whats the atomic mass of thallium 203 and thallium 205?
the overall atomic mass is 204.37, but for thallium 203 it is 203, and for thallium 205, it is 205.
The metal thallium occurs naturally as 30 percent thallium - 203 and 70 percent thallium - 205 calculate the atomic mass of thallium?
(203 x 0.30) = 60.9 (205 x 0.70) = 143.5 60.9 + 143.5 = 204.4 The answer is 204.4 amu !
Answer the alpha decay undergo in nuclear equation thallium-230?
There is no thallium-230 isotope.Also no thallium isotope decays by alpha decay, the unstable isotopes all decay either by K capture or beta decay.
How many protons does thallium-201 have?
Thallium has 81 protons.
Why is 81 the answer to how many protons and neutrons in a thallium atom?
Thallium has 81 protons. Look on the periodic table. Thallium is number 81. That means it has 81 protons.
