you mess around injecting things with odd stuff you probably shouldn't even be near
8. In a fission reaction-
three nuclei split then combine into one
small nuclei combine to make big ones
a big, unstable nucleus can split into smaller ones when ,for example, absorbing a neutron
an atom splits into two smaller ones
9. true or false- all nuclear reactions can be sources of energy
From a certain point of view
Idk
true
false
10. How are chain reactions controlled?
other
nuclei are kept stable
use a different material to absorb neutrons,slwoing the recation down as there are fewer neutrons to stimulate more fission recations
we don't know how to control a hypothetical chain reaction yet
11. Only one neutron from each _____ can cause another _____
atom
fission
chain reaction
fusion
12. Why is fusion difficult?
Trick question!
Because scientists haven't yet figured out how it works
Nuclei have to be really close before it occurs, and as unless really high temperatures and pressures are reached to overcome this, the positive charges repel one another
Nuclei may blow up if they get to the correct heat and pressure for fusion,so there is a low chance of them being able to fuse
