Are the nuclei of final elements produced by nuclear decay more stable or less stable than the nuclei of original radioactive elements?
Of course they are more stable, therefore they formed naturally.
What is the difference between nuclear decay and nuclear fission?
Nuclear decay is any spontaneous process where unstable nuclei release extra energy to arrive at a more stable state. Typical decay processes are Alpha, Beta, and Gamma. Some large unstable nuclei (e.g. Plutonium-240) can sometimes decay by spontaneous fission.Nuclear fission is a process where certain large nuclei (e.g. Uranium-235 & Plutonium-239) absorb a neutron and then split into two smaller nuclei and a few free neutrons. Some large unstable nuclei (e.g. Plutonium-240) don't need to be hit by a neutron to fission.Nuclear fusion is a process where small nuclei under unusual conditions of very high temperature and very high pressure combine to form larger nuclei.All three processes above are exothermic.In stars nuclear fusion stops at nickel and iron (further fusion past this would be endothermic). If all we had was the above processes then that would be where the periodic table ended (therefore there could not be nuclear fission as such heavy nuclei could not exist). However stars die, and some die so spectacularly we call them supernovas.When a supernova occurs, an intense shock wave blows all the outer layers of the star away at very high velocity. At these velocities nuclei collide so hard that normally impossible endothermic nuclear fusion reactions occur. The rest of the periodic table is filled here, including many transuranics not found naturally on earth (e.g. Americium, Californium, Berkelium).
Radioactive decay occurs when atoms of an unstable element?
It means that massive nuclei break apart.
What phylum does scorpions belong to?
Scorpions are members of the phylum Arthropoda, and all arthropods belong to the taxonomic domain of Eukarya, members of which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
When was Kingdom Come - band - created?
Kingdom Come - band - was created in 1987.
Do members of the Monera Kingdom have nuclei?
no
What kingdom has simple cells that lack nuclei?
prokaryotes
Which kingdom has cells that lack nuclei?
prokaryotic cells
Which is the only kingdom in which its cell do not contain nuclei?
Monera (eg. bacteria)
Do bacterial cells contain nuclei?
No they don't i dont' think
Which kingdom contain one celled living things without nuclei?
Monerans.
What do plant and fungi kingdom have in common?
They are both eukaryotes,have cell walls, have nuclei,and are multicellular.
What 2 kingdoms do not have nuclei?
1 kingdom i know of that DOESNT have a nucleus is Eubacteria.
How domains and kingdoms differ?
Domain and kingdom are different because the domain tells you if the cell has nuclei or not (eukaryote). The Kingdom tells you if it is a plant, animal, or fungi.
How is the 5 kingdom system the same as the 6 kingdom system?
i dont knpw
Where did Isambard Kingdom Brunel live?
if you dont know dont answer! dont just say hello i dont know
What kingdom are single celled organisms without nuclei such as escherichia coli which live inthe human body?
Monerans I think
