[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom.
It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne].
Adding one electron to fluorine makes it F negative. Fluorine has seven valence electrons, and adding one electron gives it a full octet.
1s2 2s2 2p5
Or
[He] 2s2 2p5
Then [He]
Fluorine is normally: 1s22s22p5 But with the addition of an electron to make F-, the answer is: 1s22s22p6
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
A fluorine atom that has seven electrons in its outer shell would be neutral. A negatively charged fluoride ion, Fl-, forms when a fluorine atom gains one electron so that it has an octet, or a noble gas configuration of electrons.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom.It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne]
The electron configuration for an atom of fluorine is [He]2s2.2p5.
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.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
The electron configuration for an atom of fluorine is [He]2s2.2p5.
1s2,2s2,2p5
The answer is carbon
A fluorine atom gains one atom in order to achieve the same electron configuration as neon. In doing so, the fluorine atom forms a fluoride ion with a 1- charge with the formula F-. As a negatively charged ion, it can form ionic bonds with various positively charged ions.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
Fluorine is normally: 1s22s22p5 But with the addition of an electron to make F-, the answer is: 1s22s22p6
The electron configuration of fluorine is 1s2 2s2 2p5.
Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5
