Question

2 circle the correct bold word for each choice:
in this experiment, the metal cations’ electrons were initially in the (ground, excited) state.
when placed in the flame, the electrons then (absorbed, emitted) energy in the form of
(electricity, heat). when this occurred, electrons made transitions from (low, high) energy
levels to (low, high) energy levels. the electrons were then in the (ground, excited) state. the
electrons in these metals then made transitions from (low, high) energy levels to (low, high)
energy levels, resulting in the (absorption, emission) of energy as (electricity, heat, light).

Explanation:

1. Initially, electrons in metal cations are in the ground state (stable, lowest energy).
2. When placed in a flame, electrons absorb energy (in the form of heat from the flame).
3. Absorbing heat causes electrons to transition from low to high energy levels, entering the excited state.
4. Excited electrons then transition back from high to low energy levels, releasing energy via emission (as light, producing the flame color).

Answer:

1. (ground)
2. (absorbed), (heat)
3. (low), (high)
4. (excited)
5. (high), (low)
6. (emission), (light)
