During a flame test
protons move from the nucleus into
the electron cloud. Their movement
generates a photon of light.
electrons transform into protons to
produce light.
electrons absorb energy and jump to an
excited state. They release energy, give off
light and return to their ground state.
protons absorb energy and jump to an excited
state. They return to their ground state,
release energy, and give off light.
A lithium ion is much less reactive than a lithium atom because it
is much more massive.
has a full outermost energy level.
has a negative electric charge.
is in a different group in the
periodic table.
Most halogens form compounds by
gaining an electron to form a
negative ion.
losing an electron to form a positive ion
losing protons.
