Which element's second ionization energy level is large compared to its first ionization energy?
Cl
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.
Why ismthe second ionisation energy greater than first for lithium?
The second ionization energy for lithium is greater than the first because removing the second electron requires breaking a stronger bond due to the higher effective nuclear charge after the first electron is removed. This leads to a greater energy input to remove the second electron compared to the first.
What is the significance of the first ionization energy of s in determining the reactivity of an element?
The first ionization energy of an element, like sulfur (s), is important in determining its reactivity. A low first ionization energy means it is easier for the element to lose an electron and form a positive ion, making it more reactive. Conversely, a high first ionization energy means it is harder for the element to lose an electron, making it less reactive.
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.
What element with the electron arrangement 287?
The element with the electron arrangement 2-8-7 is fluorine, which has the atomic number 9. Fluorine has 9 electrons, arranged as 2 in the first energy level, 8 in the second energy level, and 1 in the third energy level.
What element has the electronic structure 2.7?
The element with electronic structure 2.7 is lithium (Li) with an atomic number of 3. It has 2 electrons in the first energy level and 1 electron in the second energy level.
Which element's second ionization energy level is large compared to its first ionization energy?
Cl
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.
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.

This leads to a greater energy input to remove the second electron compared to the first.
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.
What has a second ionization energy level of 1577?
The element that has the highest second ionization energy is Li. When you remove the first electron from Li you are down to the 1s orbital. They are harder to remove because they are closest to the nucleus.
Which element has configuration 2.7?
The element with the electron configuration of 2.7 is chlorine (Cl). This configuration indicates that chlorine has 2 electrons in its first energy level and 7 electrons in its second energy level. Chlorine is a halogen and is known for its reactivity, often forming compounds by gaining an electron to achieve a stable octet.
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.
