how did I get here all I remember is that there was an explosion in my science class, we were studying atoms the building blocks of life and it is also the smallest unit of matter.
no he means protons a subatomic particle with a positive charge and it's in the nucleus with an AMU of 1
good morning boys and girls today we're studying atoms!
do you mean the nucleus the center of the atom with a positive charge where protons and neutrons live
or the electron cloud that surrounds the nucleus and contains the electrons?
HA HA HA.....NO
of course you also forgot the electron the subatomic particle with a negative charge which is in the energy levels and in the electron cloud and the AMU is almost zero!
don't energy levels surround the nucleus and the electrons fill order is 288
that's correct but there's also a neutron a subatomic particle with a neutral charge that is in the nucleus with an AMU of 1!
hey guys look I'm going to split an atom
but then of course there's the atomic number the number of protons identifies the element that is equal to the number of electrons. but then of course there's valence electrons, electrons in the outermost energy level
but then there's atomic mass proton AMU + Neutron Amu
