"Excited", or in an "excited state".
Like a ladder, the electrons can be on discrete energy levels. Just like you can't be stepping halfway between the rungs, the electrons can't exist in between the energy levels.
6 p-shell electrons.

Electrons can exist only in certain allowed discrete energy states/ Photon absorption and emission are the result of transitions between energy states/ Electrons with more energy have orbits further from the nucleus
These electrons are called "excited".
An electron may move to an electron shell farther out from the nucleus.

When an atom gains or loses energy, electrons are the subatomic particles that jump between energy levels. Electrons exist in distinct energy levels or shells around the atomic nucleus. These energy levels are quantized, meaning electrons can only occupy specific orbits. When an atom absorbs energy, typically in the form of light or heat, electrons can move to a higher energy level (excited state). Conversely, when an electron loses energy, it returns to a lower energy level (ground state) by emitting energy, often in the form of light. This process is governed by the principles of quantum mechanics and is described by the Bohr model for simple atoms and the more accurate quantum mechanical model for complex atoms. In the quantum mechanical model, electrons are described by wave functions, and their behavior is probabilistic, reflecting the uncertainty principle.

It takes no time as electrons can not exist in an inbetween state of charge

D.) Electrons exist in energy levels
Because, due to the absorption of heat energy by the calcium atom in the flame. The electrons in the atom get promoted to a higher energy level, and exist in an unstable excited state. As they are unstable and prefer to be at their normal ground state, the extra energy that the electrons absorbed to be promoted in the first place is emitted in the form of a photon, light. The light emitted from the electrons of the calcium atoms will be at a specific wavelength, which is the red light you see emitted from the flame.
