physics Flashcards
what 2 particles does atoms contain in the nucleus.
neutrons and protons
what smaller particle is circling around the nucleus
electrons
what 2 types of electrical charges are there
positive and negative
what electrical charge does protons have
positive
what electrical charge does electrons have
negative
what electrical charge does neutrons have
non neutrons don’t have an electrical charge
how does the atom stay stable
it has an equal number of negative and positively carged protons and electrons
this makes atoms non electrical ( electrical neutral)
what 2 particles have the same mass
neutrons and protons mass of 1
what mass does electrons have
almost 0
why can a atom be unstable
has the wrong ratio of neutrons and protons.
how does a atom become stable
the nucleus can emit an energy-carring particle
what happens when the nucleus emits an energy-carring particle
a different atom is formed due to different number of neutrons and protons to the original nucleus
what is a nuclear radiation
nuclear radiation is a particle or wave emitted from the unstable nucleus of an atom
what are the 3 main nuclear radiation
alpha particles
beta particles
gamma rays
