Thermal energy can also raise the electron to a higher energy state...Electrons can also be excited by electrical excitation, where the original electron absorbs the energy of another, energetic electron. The simplest method is to heat the sample to a high temperature.
Read this statement from the internet, in which what the other ways were to move electrons to higher shells.So can you confirm that there are 3 SOLID ways to move electrons to higher shell levels.Here are the statements I read" Thermal energy can also raise the electron to a higher energy state, which is what is happening in your metal salt burning experiment. The cause of excitation is the heat, and light is emitted when the electron returns to the ground state. Each metal salt has a characteristic light color that it releases. Metal salts can be incorporated into fireworks to give them color. In addition to light and heat, another way that electrons can get excited is through the direct transfer of energy that occurs when the electron collides with another atom or electron."So thermal energy is another way, also another statement I read."Electrons can also be excited by electrical excitation, where the original electron absorbs the energy of another, energetic electron. The simplest method is to heat the sample to a high temperature. The thermal energy produces collisions between the sample atoms causing the atom's electrons to be excited.When an excited electron falls back to a lower energy state again, it is called electron relaxation. The resulting emission spectrum can be used to determine the composition of a material, since it is different for each element of the periodic table."Are these guys talking about electromotive force like some of you guys on naked scientists forum told me about.I am grateful for your help, anything helps, even a few words.
