Manganese-56 is a beta emitter with a half-life of 2.6 hour. What is the mass of manganese-56 ina 1 mg sample of the isotope after 10.4?

you do 10.4/2.6 to get 4. then you have to divide 56 by 4 half lives.
56/2/2/2/2= 3.5g

Is californium poison?
Californium is radioactive and a strong neutrons emitter; californium may be a cause of cancers and can be lethal.
How is californium dangerous?
Californium is dangerous because is very radioactive (gamma or alpha, depending on the isotope) and also a strong neutrons emitter. Californium may be a cause of cancers.
What are the names of the of the unstable hydrogen isotopes?
The only UN-stable Hydrogen isotope is Tritium, atomic number 1 (of coarse!), mass number 3, with 2 neutrons in nucleus, beta- electron emitter, (max.) 0.018 MeV, half-time 12.3 yr.
What is the stable isotope that is formed by the breakdown of a radioactive isotope?
That's called a daughter isotope, or a daughter product. (The original isotope that decayed is the parent isotope.)
Mass number of actinium?
Unable to answer without knowing the specific isotope. However I will assume you mean actinium-227 as it is the only isotope with a halflife longer than a few days.227 protons and neutrons each composed of 3 quarks, total 681 quarks89 electronsThis gives a total of either 316 electrons, protons, and neutrons or 770 electrons and quarks. However this does not count the undeterminable number of virtual photons, muons, and gluons being exchanged by those electrons, protons, neutrons, and quarks to couple the electromagnetic, weak, and strong forces between them.
Is lithium 8 an isotope why?
Yes, but it has a halflife of only 0.86 seconds.
Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.
Is any isotope of lead is radioactive?
many. one example is lead-214 with a halflife of 26.8 minutes.
What is the time needed for half of a sample of a radioactive isotope to break down to form daughter isotopes called?
halflife
What are the naturally occurring isotopes of polonium?
This isotope is 210Po, an alpha emitter with a half life of 138,376 days.
What is actinium -227?
Actinium-227 is a natural isotope; the half life is 24,77 years. It is a emitter of alpha and beta.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
How does californium help medical care?
The isotope californium-252 (a neutron emitter) is used for the treatment of cervical and brain cancers.
How does uranium 234 behave?
Uranim-234 is a rare natural isotope of uranium - the abundance is 0,0054 %.This isotope ha 92 protons, 142 neutrons and an atomic mass of 234,040 952 1(20).His halflife is 245 500 years.
Explain thorium as a type of radiation source?
The natural isotope 232Th is an alpha particles emitter but it is not important and it is not used as a source of radiations.
Why is americium-241 ideal to use in gauges?
Americium 241 is an artificial isotope with a long half life - 432,2 years - and a gamma ray emitter. Being a strong gamma emitter it can be used for gamma radiography of materials and for thickness gauges.
Is californium poison?
Californium is radioactive and a strong neutrons emitter; californium may be a cause of cancers and can be lethal.
