WebIt therefore has 7 valence electrons and only needs 1 more in order to have an octet. One way that this can happen is if two F atoms make a bond, in which each atom provides one electron that can be shared between the two atoms. The resulting molecule that is formed is F 2, and its Lewis structure is F—F. WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts.

Web28 apr. 2024 · Oxygen is found in Period 2, Group 16. Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron. Exclude groups 3 through 12. WebAcross a period, the number of electron shells remains the same, while the number of electrons increases. This has to do with the number of electron shells. While the number of protons and the nuclear size still does increase across a period, the atomic radius actually decreases. ‍Things are a little different when you look across the periods, though. how many human years is a light-year
