What is the electron configuration of Li and F?

The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.


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 electron configuration of florine?

1s2 2s2 2p5


1s2 2s2 2p5?

The electron configuration of 1s2 2s2 2p5 is for the element fluorine. Fluorine is a corrosive and poisonous gas. It has an atomic number of 9 and its group number is 17.


What is the short form electron configuration for fluorine?

1s2 2s2 2p5


What is the general electronic configuration of f-block elements?

Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5


What is the difference between fluoride's electron configuration and fluorine's electron configuration?

Fluorine's electron configuration is 1s2 2s2 2p5, and since fluoride is just fluorine with an extra electron, or F-1, its electron configuration is 1s2 2s2 2p6.


What is the noble gas notation for F?

The electron configuration of francium is [Rn]7s1.


What is the condensed electron configuration of fluorine?

Fluorine's atomic number is 9. Thus, neutral fluorine has 9 protons and 9 electrons. It's total configuration then is 1s2 2s2 2p5, so its valence configuration is 2s2 2p5.


Write the noble-gas electron abbreviation of chlorine?

The electron configuration of fluorine is 1s2 2s2 2p5.


What is the outermost electronic configuration of the most electronegative element?

Electronegativity is, to some extent, a subjective value (though based on a composite of actually measurable physical properties). The highest electronegativity is usually assigned to fluorine. The electron configuration of fluorine's outermost shell is 2s2 2p5.


Why electron affinity of fluorine is large?

Electron affinity of an element is defined as the energy released by adding an electron to a gaseous atom of the element. With the electronic configuration of the fluroine atom being [Ne] 2s2 2p5, it needs just one more electron to form the fluoride ion (F-) which has the noble gas structure and is much more stable.
