It is important to read the questions carefully and answer the question.
If the question is 'What is a beta particle?' the answer would be 'an electron'. Everything else is 'icing on the cake'. i.e they describe it - it has a small mass, it comes from the nucleus when a neutron changes to an electron + proton, it has a negative charge. These are all things things which describe the beta particle - they don't say what it is. There is a subtle difference.
The key information - its an electron!!
Example
What is a camera? Ans: Its is a device for taking photographs.
Wrong answer - It weighs about 90 g, sometimes its black or silver, it has a lens, it might be digital and I got one for Christmas.
Get the idea?
