Answer:
The correct option is B. an alpha particle.
Explanation:
When ²³Na is bombarded with protons 
, ²⁰Ne and one alpha particle 
is released.
The reaction is as follows:
Therefore, an alpha particle and ²⁰Ne are released when ²³Na is bombarded with protons.
In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235.
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.
Solution :
Given :
L = 1 in
d = 0.75 in
D = 1 in
Fillet radius, r = 0.063 in
We know that :
MPa
= 130 MPa
Therefore, the stress concentration factor is :
= 1.157922
The number of protons tells you what element an atom is. Just knowing the number of neutrons/mass number does not tell you what element an atom is, since atoms of the same element can have different mass numbers. But all atoms with the same number of protons, are also always of the same element.
Hence, we can identify an atom by the number of protons it has
