Write a generic lewis structure for the elements in the oxygen family (group 6a).

If we talk about elements of group 6a , they have 6 electrons in the outermost shell as the group number indicates. There are 6 elements in group 6a including  oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po).

The general electronic configuration of its all elements is ns^2, np^4 . They need only two electrons to complete their octet therefore, many exist as anions. Their generic Lewis dot is mentioned in the figure and here X indicates group 6a elements.

Hope it helps!

i do not know

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
