Would you expect the second electron gain enthalpy of O as positive more negative or less negative than the first Justify your answer?
The second electron gain of an oxygen atom would be expected to be less negative. The reason for this outcome is that the oxygen atom gaining a second electron already has one electron and thus a negative charge. This negative charge repels the second electron to some extent, making the enthalpy of this process less negative than when the first electron was added to the neutral oxygen atom.
When compared with the energy of an electron in th first shell of a carbon atom the energy of an electron in the second shell of a carbon atom is?
greater
How does the electron transport chain transfer light energy photosynthesis?
Light breaks down water into hydrogen and oxygen, the oxygen is then released. Next the hydrogen and its electron separate so that they are H+ and e-. The electrons are dragged across which creates massive energy.
Do an atom's successive ionization energies increase regularly?
No, an atom's successive ionization energies do not increase regularly. The first ionization energy, which is the energy required to remove the outermost electron, is typically lower than the second ionization energy, which is the energy required to remove the second electron. The ionization energies generally increase as more and more electrons are removed from an atom. However, there can be irregularities due to factors such as electron-electron repulsion and electron shielding.
What is second ionization energy of hydrogen?
hydrogen has only one electron so after you remove that electron you do not have any electrons left to remove so hydrogen doesn't have a 2nd ionization energy. hydrogen has 1 proton and 1 electron.
Which electron in oxygen have the higher energy those in the first energy level or those in the second?
The second level is associated with higher energy than the first is. Keep increasing the energy of an electron enough, and eventually it breaks free of the atom completely.
What is the numbers of electron in the outermost energy level of an oxygen atom?
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
If an electron is in the second energy level in which type of orbitals could this electron be in?
If an electron is in the second principle energy level, that is, n = 2, then that electron could be in an s or p orbital.
What happens when an electron moves from the excited state to the ground state?
when an electron moves from excited state to ground state it emits photons of wavelength equal to the difference between the two energy levels. Consider a hydrogen atom. If the electron is at the second energy level in the atom (the energy of this level is -3.4 eV )it can stay there for about only 10^-8 s and then after that it just to the level below .If it jumps from second to ground state (energy of ground state is -13.6 eV) it emits aphoton of energy = 13.6-3.4 =10.2 eV. .............................Gho$t
Which electrons in oxygen have more energy those in the first energy level or in the second?
More energy have the electrons in the second level of energy.
Why does Be have a much larger second ionization energy than the first?
The energy to remove 1 electron is the first ionization energy. To remove a second electron requires more energy. This is because the electron being removed now has to overcome the +1 positive charge introduced after the 1st electron was removed.

What do we mean by the first second third ionization energies for a particular atom?
First ionization energy is the energy required to remove the first outermost electron from an atom. The second ionization energy is the energy required to remove the next available electron, and is greater than the first IE. The third IE is that energy needed to remove the third electron, and is greater the the second IE.
The first element with an electron in the second energy level?
Lithium
What is the second electron affinity positive or negative?
It is positive. In relation to oxygen at least.
Would an electron have to absorb or release energy to jump from the second energy level to the third level?
Electrons are attracted to the nucleus of the atom of which they are a part; this is because of the electrostatic force between the negatively charged electron and the positively charged nucleus. Therefore it takes energy in order to pull an electron farther away from the nucleus and to enable it to remain at a greater distance. This is exactly the same phenomenon as raising a heavy object such as, let us say, a bowling ball, to a greater elevation. It takes energy to do it, since you have to overcome the force of gravity.
