The valence electron configurations of several atoms are shown. how many bonds can each atom make without hybridization? 2s^2 2p^3

3 bonds

Why?:
In 2p3 we have 3 unpaired electrons as the electrons in 2s2 are paired
whereas the electrons in 2p3 are unpaired (as max number of electrons in p sub shell is 6 so 2 in each of the 3 orbitals but we put single electrons in first so all 3 orbitals are filled)
so another atom can form bond pairs with those 3 unpaired electrons without hybridisation to form a full octet.

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
