If this is from study island, which I assume it is, I just got this question and the answer is
Potassium (K)
Sulfur has six valence electrons and can therefore attain an inert gas configuration in two different ways: by accepting two electrons to attain the electron configuration of argon or donating or sharing six electrons to attain the electron configuration of neon. In combination with the much less electronegative element sodium, sulfur accepts one electron from each of two sodium atoms to form the ionic compound Na2S, but in combination with the more electronegative element fluorine, sulfur shares its six valence electrons with each of six fluorine atoms to form six polar covalent bonds with fluorine.
Beryllium would have that configuration
this is because a fluorine ion is one electron short of a full valence shell,which makes getting another electron to fill the shell very favourable,filling the shell makes the molecule much more stable
fluoride
This electron configuration is for osmium (Os).
The electron configuration for an atom of fluorine is [He]2s2.2p5.
The answer is carbon
The electron configuration for an atom of fluorine is [He]2s2.2p5.
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.
There are a total of 9 electrons so that would be the element fluorine.

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.
When fluorine (F) takes an electron from sodium (or from any element in an ionic bonding scenario), the 2p6 sub-orbital is filled, which allows fluorine to achieve the electron configuration of nearby neon (Ne).
Because each of them can form a cation with the electron configuration of a noble gas by donating one electron to another element.
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.
If you mean 1s22s22p3, you would refer to the periodic table. Using 2p3, you would look at the second period (row), look at the p block, and count 3 elements to the right to find nitrogen.
This element is fluorine.
