Which is the electronic configuration for oxygen?
1s2 2s2 2p1
1s2 2s2 2p3
1s2 2s2 2p4
1s2 2s2 2p6

                     1s², 2s², 2p⁴

                      Electronic configuration is the distribution of electrons of an atom in atomic orbitals. As we know Oxygen is a non metal and is present in group 6 and period 2 with atomic number 8. The atomic number in fact specifies the number of protons. Hence, for a neutral oxygen atom there must be 8 electrons to balance the charges of protons.

                        These 8 electrons are distributed in two main energy levels i.e. n = 1 and 2 and sub energy levels i.e. s and p. According to certain rules like Aufbau Principle, Pauli's Exclusion Principle and Hund's Rule the electronic configuration for eight electrons is as,

                                           1s², 2s², 2px², 2p¹, 2p¹

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /
