The second ionization energy of oxygen is greater than fluorine because in oxygen, after the first electron is removed, the remaining electron is from a filled shell (2p^4). This electron in oxygen experiences greater electron-electron repulsion, making it harder to remove compared to the outer electron in fluorine which is in a half-filled shell (2p^5).
What else can I help you with?
The element fluorine has 9 electrons. Which is the electron configuration for an atom of fluorine?
The electron configuration for an atom of fluorine is [He]2s2.2p5.
Which elemets are in the second period?
The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
How many electrons are in the highest energy occupied shell of a fluorine atom?
The highest energy shell of Fluorine is 2nd shell which contains 7 electrons just like other halogens.
How many electrons are in the third energy level of oxygen?
There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
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.
How does fluorine's electronegativity compare to the electronegativigty of oxygen and chlorine?
Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.
How many electrons does fluorine second energy level have?
9
Why the second ionization energy of Ca is lower than the second ionization energy of k?
Because with the 2nd ionisation of K, you are trying to take an electron from a fully filled orbital (octet rule) whereas with calcium it is getting down to a fully filled orbital
An atom of fluorine has 9 electrons.Its second energy level has?
The second energy level of an atom of fluorine will have 7 electrons. This is because the first energy level can hold a maximum of 2 electrons, and the second energy level can hold a maximum of 8 electrons. Since fluorine has a total of 9 electrons, 2 of them will be in the first energy level and 7 will be in the second energy level.
The element fluorine has 9 electrons. Which is the electron configuration for an atom of fluorine?
The electron configuration for an atom of fluorine is [He]2s2.2p5.
What is the third ionization energy for fluorine?
Second ionization energy of fluorine is the amount of energy needed to remove an electron from a unipositive fluorine atom (F+)to form F2+,in all the gaseous state
Which elemets are in the second period?
The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
Why does neon have a higher second ionization energy than fluorine?
Neon has a higher second ionization energy than fluorine because its first ionization energy removes an electron from a stable noble gas configuration, resulting in a very stable ion. In contrast, fluorine's second ionization energy involves removing an electron from a more unstable anion (F⁻), which is easier than removing a second electron from neon's filled outer shell. Additionally, the effective nuclear charge experienced by the remaining electrons in neon is higher, making it more difficult to remove the second electron compared to fluorine.
How does fluorine's atomic radius compare to oxygen's radius and chlorine's radius?
Fluorine's atomic radius is smaller than that of chlorine but larger than that of oxygen. This trend is due to the increasing number of electron shells: fluorine and oxygen are in the second period, while chlorine is in the third. Consequently, fluorine has a greater effective nuclear charge compared to oxygen, pulling its electrons closer, while chlorine has additional electron shells, leading to a larger radius. Thus, the order of atomic radius from smallest to largest is: fluorine < oxygen < chlorine.
Can you draw a bohr model for fluorine?
Fluorine has 9 electrons. The first energy level holds 2 electrons, and the second energy level holds 7 electrons. The Bohr model for fluorine would show 2 electrons in the first energy level and 7 electrons in the second energy level.
