Subatomic Particles
This is where protons and neutrons are located.
nucleus
Isotopes have the same protons but different ____
neutrons
This type of decay loses 2 protons and 2 neutrons (a helium atom or alpha particle)
alpha decay
The first ring of Bohr model can hold __ electrons.
2
This particle has no charge and is found in the nucleus.
neutron
This number changes when you have isotopes because of the different number of neutrons.
atomic mass
This type of decay is when the nucleus loses a beta particle or electron.
