Yes, that's exactly what it is: when you lose energy your level is lower.

How does the energy of an electron change when the elctron moves closer to the nucleus?
the electrons moving closer to the nucleus have lower energy level.why?AnswerWhen atoms absorb energy, electrons move into higher energy levels, and these electrons lose energy by emitting light when they return to lower energy levels.It's like a sea saw, you go up, you get energy, go back down, lose it.please recommend me :D
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
Can electrons lose energy at ground state explain?
No. At ground state, the electrons are at their lowest energy.
Why does an electron loose energy in its ground state while revolving round the nucleus with changing acceleration?
This was a burning question about a hundred years ago. (Actually, technically, the question was why electrons did not lose energy etc. etc. since it was known that they did not do so.) We now know that this model of the atom is completely wrong. Well, okay: the nucleus is in the center, more or less; that's still true. # Electrons don't lose energy in the ground state; # Electrons don't revolve around the nucleus; # There's no change in acceleration, because there's no acceleration involved. The reason electrons don't lose energy is because electrons obey the mathematics of quantum mechanics, which allows only specific bound-state energy levels because only those energy levels are eigenvalues for the Schroedinger equation.
Why is it easier to lose electrons from a cesium atom than from a lithium atom?
It all has to due with ionization energy. Ionization energy is the energy required to remove an electron from an atom to make it an ion. Cesium has a lower ionization energy than Lithium, so it is easier to remove electrons, and thus lose electrons, from a Cesium atom than a Lithium atom.
Why does an element lose 4S electrons before 3D electrons?
Because 4s is a lower energy level and 3d is higher. In fact, s levels should, strictly, be written first before d levels when writing electron configurations.
What are elements lose electrons and form positive ions named?
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.

Why calcium and magnesium impart colors to the fllame?
When calcium or magnesium is heated by a flame, the outer electrons of the metal ions in the structure are given energy. That energy excites them to a higher energy level. The electrons rapidly lose this energy and emit it, dropping down to lower energy levels. This energy corresponds to a certain frequency, and thus wavelength, of light using the formula below. The flame therefore appears that colour. E = hν Where E = energy, h = Planck's Constant and ν = frequency Energy levels are pre-defined and electrons can only rest in these specific energy levels. That is what gives the flame the same colour each time.

Why a stairway is a good model for the energy levels in a 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.
When compounds gain electrons they lose or gain energy?
Lose
Which family of the periodic table has the strongest tendency to lose electrons and why?
This is the alkali metals family; the ionization energy is lower for these chemical elements.
Can electrons lose energy at ground state explain?
No. At ground state, the electrons are at their lowest energy.
How can you can increase or decrease the energy possessed by electrons?
Electrons can absorb photons and gain energy, and they can emit photons and lose energy.
What do electrons do in Bohr's atomic model?
In Rutherford's Atomic Model, electrons in a circular orbit around a nucleus should emit radiation -- and emit it so rapidly that the electrons should lose all their orbital velocity in less than a millionth of a second. Bohr proposed that electrons are, instead, fixed at specific orbitals (*NOT* orbits!!), each of which has the electron at a specific energy level. Energy is only given off from an atom when an electron goes from an orbital at a higher energy level to one with lower energy. According to Bohr, electrons simply go between fixed energy levels around the nucleus.
