So why isn't energy released when combining the two bowls of potatoes? I mean each bowl is a combination of protons and electrons and neutrons, right? So we combine both and don't release energy, but when we combine an electron and proton we do release energy?
Thanks for the refresher.
The reason I asked was because I was thinking about how a hydrogen atom could weigh less than when it's proton and electron are considered individually. This is due to negative binding energy, meaning you have to put energy into the atom to seperate the proton from...
Just a quick (hopefully not too dumb) question :
How do physicists determine the mass of an electron? Is there a device or experiment used? I am just confused because of its particle / wave properties.
