Which element has seven energy levels?
When the element is heated, electrons in its atoms are sent into higher energy levels. From there they can lose energy and this is when light is emitted. Each element has its own particular energy levels. The light is an "emission spectrum" and it's different for each element. The detailed explanation involves quantum mechanics.
What do you notice about the number of energy levels in an atom of an element and period the element is in?
Super easy way: whatever row the element is in is the number of energy levels it has. Example: hydrogen in the first row, it has 1 energy level. actually, the easiest way to find the number of energy levels to the nucleus is to look at the top right hand corner and see the number in the chart of the element, however many numbers there are in that right hand corner of the elemnt is…
It depends on what element the atom is. For example if it is Hydrogen it has one ring or energy level. The higher the element's atomic number is on the periodic table the more energy levels it will have. Actually, every atom has an infinite number of energy levels. Yes, hydrogen has as many as plutonium or gold. The difference is how many of these levels are filled with electrons. When asking about how many…
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
These colors are generated by excited electrons relaxing back to lower energy levels. Each element has unique energy levels permitted to electrons by quantum mechanics. As an electron drops to a lower level a photon is emitted, carrying away the difference in energy and the higher the energy the shorter its wavelength.
