well done, so did I cos i got wat u got lol
Question if the electron is the most 'important' sub atomic particle then isnt a positron equally as 'important'
'start physics
Remembering that (goin into physics here') Newtons states that for every action there is an equal but opposite reaction.
For example in a circuit powered by any type of power source, electron flow is measured as Voltage(V) however Current is deemed to move in the opposite direction to electron flow and was proved/found (by someone dunno who) to be the flow of 'positively charged electrons' now known as positions.
'end physics
So yea, after this is the electron still the most important sub atomic particle. I honestly doubt that you could claim any 1 particle to be the most important, however from my current knowledge assuming what i have said earlier is correct i would assume the neutron.
MY QUESTION
A neutron is a proton + electron or is it a positron + electron
either way it is the result of two particles of opposite charge one of which is an electron.....

In this world of ours (i.e. to the limits of the known universe), by its very nature a positron has no real 'chemistry' besides going BOOM when coming in contact with an electron.
A positron is not just a 'positively charged' electron...it IS anti-matter.
When we ask what is the most important sub-atomic particle...you must first ask yourself, what does 'important' mean?
Important to me mean, that which determines the majority of physical and chemical properties of a substance...by this definition, the electron is by a long stretch the most relevent, both in the classical realm and the quantum realm.
Think about all you understand about chemistry and ask yourself, how many of the concepts are a consequence of the nature and behaviour of electrons...

For question 8, a beta particle is the same as an electron...right? If so, then why is (a) the correct answer rather than (c)?
Edit: Never mind, I just found out that a Beta-particle is a high-energy particle which has more energy than an ejected valance electron, thus more than 'just an electron'...
