Why it is difficult to remove an electron from halogens?
In their outer electron shell, halogens have 7 valence electrons, one less than the number needed for a full shell. Therefore, it is much, much easier for the halogen to gain an electron in bonding than for it to lose 7 - the ionization energy (energy required to remove an electron from an atom) is quite high.

How much energy is needed to completely remove an electron from n2 in a hydrogen atom?
How much energy is required to move the electron of the hydrogen atom from the 1s to the 2s orbital
What is the differences between first and second ionization energy?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
When an electron falls back to its ground state how much energy is released?
It releases the same amount of energy that it absorbed when it was excited to a higher energy state.

Why doesn't the electron lose twice as much energy when it moves in two levels as it loses when it moves only one energy level?
The energy gaps between levels are not all the same.

How much energy is required to move the electron of the hydrogen atom from the 1s to the 2s orbital
Why is the ionisation energy of fluorine higher than iodine?
The ionization energy of an atom is the energy required to remove an electron from the atom. Fluorine has a smaller atomic size and higher effective nuclear charge compared to iodine, making it more difficult to remove an electron from fluorine, resulting in a higher ionization energy. This is because the electrons in fluorine are held more tightly due to stronger electrostatic attraction between the nucleus and the electrons.
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 side of the periodic table typically have high electronegativity, meaning they hold their electrons tightly. This results in requiring a large amount of energy to remove an electron from the outermost energy level. This property is known as high ionization energy.
Why does Be have a much larger second ionization energy than the first?
Beryllium has a much larger second ionization energy than the first because after losing its first electron, the remaining electron is held more tightly due to increased electrostatic attraction from the positively charged nucleus. This results in a higher energy requirement to remove the second electron.
What is the difference between electron negativity and electrons affinity?
ok, so electron affinity is the amount of energy given off when a particular atom excepts electrons. Essentially, it is the likelihood that an atom will accept an electron, while ionization energy is how much energy is needed to take an electron off of a particular atom
What is the differences between first and second ionization energy?
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
How much energy you need to lost 1 calorie?
A calorie is a measure of energy. It doesn't make sense to ask how much energy you need to lose energy.
How many molcules are in iodine?
How much iodine...
What is auger effect?
When photons of sufficient energy are incident on a surface, an electron is ejected out from the core shell. The electron from the p-orbital or any other orbital of higher energy loses that much energy to fill up the gap created by the loss of this core electron. The energy lost by the p-orbital electron is absorbed by another electron in the same or higher shell, causing it to eject from the atom. This second atom is called the "Auger electron" and the effect is called Auger effect.
