Atomic Structure Flashcards
State the charge of the particles of an atom, (proton, neutron & electrons)
proton +1
neutron 0
electron -1
State the relative mass of the particles of an atom, (proton, neutron & electrons)
proton 1
neutron 1
electrons 1/1840
what is a proton number
the proton number is the number of protons in the atom
what is a nucleon number
the nucleon number of an atom is the total number of protons and neutrons
The no. of protons = no. of electrons in an atom, true or false
TRUE!
Describe the structure of an atom
the nucleus of the atom contains protons and neutrons while electrons orbit around in electron shells.
what is a mass number?
number of protons and neutrons, same as nucleon number
what is an atomic number?
number of protons, same as proton number
