The element beryllium has atomic number 4 and appears in the Group 2 column of the Periodic Table. It has two electrons in its valence shell (like all the other Group 2 elements), and we write it by using its chemical symbol (Be) and two dots like this: Be:
BeF2 forms, with one beryllium central to the two fluoride ions. each fluorine has seven electrons to start, gaining one electron from beryllium each.
H:F with 3 electron pairs (6 electrons) around the F atom. (Too difficult to draw on this site). And as a side, it is called hydrogen fluoride (not hydrogen fluorine).
