Final answer:
The effective nuclear charge for a 2p electron in a nitrogen atom is 5.
Explanation:
The effective nuclear charge (Z_eff) experienced by an electron in an atom is the net positive charge experienced by that electron due to the nucleus, taking into account shielding effects from inner electrons.
For a 2p electron in a nitrogen atom, there are five protons in the nucleus (atomic number of nitrogen is 7), but there are also two inner electrons in the 1s orbital, which shield some of the positive charge from the nucleus.
Therefore, the effective nuclear charge experienced by the 2p electron in nitrogen is calculated as Z_eff = Z - S, where Z is the atomic number and S is the shielding constant.
In the case of nitrogen, the effective nuclear charge for a 2p electron can be calculated by subtracting the shielding constant from the atomic number. Nitrogen has an atomic number (Z) of 7 and the 2p electron experiences shielding from two inner electrons (1s^2), so the effective nuclear charge (Z_eff) is 7 - 2 = 5. Thus, the effective nuclear charge for a 2p electron in a nitrogen atom is 5.
The given statement "What is the effective nuclear charge for a 2p electron in a nitrogen atom?" is true because it correctly identifies the inquiry about the effective nuclear charge experienced by a 2p electron in a nitrogen atom. This statement is based on the fundamental understanding of atomic structure and electron configuration.
