The outermost electronic configuration of nitrogen (2s22px12p2,2pz1) is very stable because p-orbital is half-filled. The addition of an extra electrons to any of the 2p-orbitals require's energy as it breaks the stability of N. Oxygen has 4 electrons in 2p-orbital and acquires stable configuration i.e. 2p3 after removing one electron and complete octet after gaining two electrons., A nitrogen has positive electron gain enthalpy, whereas oxygen has negative, however oxygen has lower ionisation enthalpy than nitrogen. Hence, both statements 1 and 2 are correct.
