Which of the following electron configurations represents an excited state of the indicated atom?A) Ne: 1s2 2s2 2p6B) Na: 1s2 2s2 2p6 3s2 3p2 4s1C) P: 1s2 2s2 2p6 3s2 3p2 4s1D) N: 1s2 2s2 2p

Complete question:

Which of the following electron configurations represents an excited state of the indicated atom?A) Ne: 1s2 2s2 2p6B) Na: 1s2 2s2 2p6 3s2 3p2 4s1C) P: 1s2 2s2 2p6 3s2 3p2 4s1D) N: 1s2 2s2 2p3

C) P: 1s² 2s² 2p⁶ 3s² 3p² 4s¹ → excited state

Explanation:

An excited state configuration is a higher energy arrangement of electrons.

A) Ne: (Neon has 10 electrons)

Ground state configuration:  1s² 2s² 2p⁶

Given configuration: 1s² 2s² 2p⁶ → ground state

B) Na: (sodium has 11 electrons)

Ground state configuration: 1s² 2s² 2p⁶ 3s¹

Given configuration: 1s² 2s² 2p⁶ 3s² 3p² 4s¹ → excess electrons

C) P: (Phosphorus has 15 electrons)

Ground state configuration: 1s² 2s² 2p⁶ 3s² 3p³

Given configuration: 1s² 2s² 2p⁶ 3s² 3p² 4s¹ → excited state

D) N: (Nitrogen has 7 electrons)

Ground state configuration: 1s² 2s² 2p³

Given configuration: 1s² 2s² 2p³ → ground state

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

i believe the answer is true.
