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.

Which element's second ionization energy level is large compared to its first ionization energy?

Cl


Which has the larger sixth ionization energy Se or Br?

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, etc. Ionization energy generally increases for every electron that is removed, and increases from left to right in the periodic table or if moving up the periods. In this case, from the periodic table (or according to Mastering Chemistry) Bromine (Br) has a larger sixth ionization energy than Selenium (Se).


What do we mean by the first second and third ionization energies for a particular atom?

The first ionization energy is the energy required to remove the outermost electron from an atom, forming a positively charged ion. The second ionization energy is the energy required to remove the second electron, and so on. Each successive ionization energy tends to increase because it becomes increasingly difficult to remove electrons from a positively charged ion.


What is the difference between 1st 2nd 3rd ionization energies?

The second ionization energy is always greater than the first because once you have pulled off the first electron, you are now trying to remove the second electron from a positively charge ion. Because of the electrostatic attraction between + and -, it is more difficult to pull an electron away from a positively charge ion than a neutral atom.


Which of these elements has the highest first ionization energy Si or C?

Carbon (C) has a higher first ionization energy than silicon (Si). This is because as you move across a period in the periodic table, the first ionization energy generally increases due to increasing nuclear charge pulling electrons closer. Silicon is positioned to the right of carbon in the same period, resulting in a lower first ionization energy compared to carbon.

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.

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.


What is aluminum ionization energy?

Aluminum ionization energy is the amount of energy required to remove an electron from a neutral aluminum atom to form a positively charged aluminum ion. The first ionization energy of aluminum is relatively low, meaning it does not require as much energy to remove the first electron compared to larger atoms.
