How do you write the electron configuration for F?
In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for F go in the 2s orbital. The remaining five electrons will go in the 2p orbital. Therefore the F electron configuration will be 1s22s22p5.

What is the electron configuration of an F atom in the ground state?
Fluorine atoms have 9 electrons and the shell structure is 2.7. The ground state electron configuration of ground state gaseous neutral fluorine is [He].2s2.2p5 and the term symbol is 2P3/2.
What is the electronic configuration of Li and F?
Electron Configuration Standard Notation
For example, the electron configuration of lithium is 1s22s1. The number and letter describe the energy level and orbital, and the number above the orbital shows how many electrons are in that orbital. Using standard notation, the electron configuration of fluorine is 1s22s22p5.
What is the electronegativity of F?
3.98
Fluorine/Electronegativity
The concept of electronegativity was introduced by Linus Pauling in 1932; on the Pauling scale, fluorine is assigned an electronegativity of 3.98, and the other elements are scaled relative to that value.
How many electrons does f 1 have?
Hance in anion F have on additional electron than it normal state. F have atomic number 9 so it have 9 electron in normal state and in anion 9+1 =10 electron. Thus its ion is F^- ion. It can form a negative ion only when it accepts electron, so total number of electrons in F^- ion is (9+1)=10.

Which has higher electronegativity Cl or F?
F is the more electronegative than Cl. The reasons is that it has very small size and Electronegativity depends inversely on size of element.
Is F Cl polar or nonpolar?
FCl is a polar molecule. Fluorine (F) is more electronegative than chlorine (Cl). *Note; this is conventionally written as ClF.
Which has more electron gain enthalpy F or Cl?
According to periodic properties, as we move down in a group of the periodic table the electron gain enthalpy should become less negative and fluorine is placed above chlorine yet has more negative electron gain enthalpy. Thus, the electron gain enthalpy of chlorine is more negative than that of fluorine.
Why is Cl electronegativity less than F?
Why isn’t chlorine as electronegative as fluorine? Chlorine is a bigger atom than fluorine. In the chlorine case, the bonding pair will be shielded by all the 1-level and 2-level electrons. The 17 protons on the nucleus will be shielded by a total of 10 electrons, giving a net pull from the chlorine of about 7+.
Which has highest electron affinity?
Chlorine
Which Element Has the Highest Electron Affinity? Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.
Which of the following would have a more negative electron gain enthalpy why F or Cl?
In F, the electron will be added to quantum level n = 2, but in Cl, the electron is added to quantum level n = 3. Therefore, there are less electron- electron repulsions in Cl and an additional electron can be accommodated easily. Hence, the electron gain enthalpy of Cl is more negative than that of F.
Which halogen has highest electron gain enthalpy?
chlorine
Hence chlorine has the highest value of negative electron gain enthalpy among all of these.
What has the lowest electron affinity?
mercury
What is the lowest electron affinity? Metals are more likely to lose electrons than they are to gain them. Of the metals, mercury has the lowest electron affinity.
Which has higher electron affinity O or SE?
In the periodic table Oxygen, Sulphur and selenium all are present in the same group in the order Oxygen, Sulphur, selenium. As we go down the group the size of the elements increases and the electron gain enthalpy decreases. … Hence, The correct order of electron affinity is $ O < Se < S $ .
