Dear Student,
a. These elements belong to Period 2 .
b. Nitrogen (N) is missing from the list of elements and it should be placed before oxygen and after carbon.
c.Carbon (C) element shows the property of catenation.
d. Order of increasing electronegativity : Be < N < F
e. Element which belongs to the halogen series is Flourine (F).
