How many electrons can the third energy level hold?
The third energy level has three subshells (3s, 3p, and 3d). The total number of electrons that it can house is simply the sum of the number of electrons in these subshells. Since the 3s subshell can hold 2, the 3p can hold 6, and the 3d can hold 10, the third energy level can hold 2 + 6 +10 = 18 electrons.It is important to note, however, that when filling the third energy level, the s subshell of the fourth energy level, 4s, must be filled before the 3d subshell.
How much energy does it take to make aluminum?
two electrons
Describe Why a stairway is a good model for energy levels in an atom?
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and the fourth energy level can hold 32 electrons. In order for an element to be as stable as a noble gas, the outermost energy level has to be full, so sometimes an atom will gain or lose electrons to fill it's outer energy level. Other times it might share electrons with other atoms, so that they don't have to gain or lose a lot of electrons. An example of this would be H2O ( water ). There is one oxygen atom with two hydrogen atoms connected to it, and sharing their electrons with each other.
Why is it when sodium was irradiated for 2 seconds with infrared light no electrons were rejected but when it was irradiated with ultraviolet light thousands of electrons were emitted?
Infrared light does not have sufficient energy to remove electrons from the sodium atoms because the energy of the photons is too low. On the other hand, ultraviolet light carries enough energy to overcome the binding energy of the electrons in the sodium atoms, causing the emission of electrons via the photoelectric effect.
Why do electrons have different amounts of energy at different points of the circuit?
Electrons have different amounts of energy at different points in the circuit due to the presence of components like resistors, capacitors, and inductors which can absorb or release energy as electrons move through them. The voltage across different components in the circuit determines how much energy the electrons have at that particular point.
Do electrons lose energy or speed when they cross over a resistor?
Electrons lose energy when they pass through a resistor due to collisions with the atoms in the resistor material. This loss of energy manifests as heat. The speed of electrons may decrease as a result of this energy loss.
How much energy does an object hold?
it depends on the object. be specific............
Where on the most reactive metals on the periodic table?
the bottom of the Periodic Table. why? a metal looses electrons and at the bottom of the periodic table is the lowest amount of ionization energy (the energy needed to remove electrons) with low ionization energy, not much energy is needed to remove those electrons making it faster and easier to do so.
Why electrons are used for the excitation in the argon ion lasers though light travels faster than the electron?
High energy electrons are much easier to create than high energy photons.
Why k shell has low energy than valence shell?
AnswerK-shell electrons generally have much larger binding energies than valence shell electrons. Can you give me a specific example or some more information to clarify your question? is energy level depend on electrons, i means is the shell having more electrons have more energy?
Elements on the side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms?
Elements on the right side of the periodic table require large amounts of energy to remove an electron from the outermost energy level of their atoms. It is much easier for them to gain rather than lose electrons.
What hold huge amounts of energy and their molecules are spread out as much as possible.?
Gases.
