Which element has the following electron configuration: 1s22s22p63s23p4?Group of answer choicesOxygenSulfurTitaniumChlorinePhosphorus

Step 1: Break Down the Problem

We need to determine which element corresponds to the given electron configuration: $1s^2 2s^2 2p^6 3s^2 3p^4$.

Step 2: Relevant Concepts

The electron configuration describes the distribution of electrons in an atom's orbitals. The number of electrons can help identify the element. The total number of electrons equals the atomic number of the element.

Step 3: Analysis and Detail

1. Count the electrons in the given configuration:

   • $1s^2$ contributes 2 electrons
   • $2s^2$ contributes 2 electrons
   • $2p^6$ contributes 6 electrons
   • $3s^2$ contributes 2 electrons
   • $3p^4$ contributes 4 electrons

2. Total number of electrons: $2 + 2 + 6 + 2 + 4 = 16$

3. The atomic number of an element is equal to the total number of electrons in a neutral atom. Therefore, the element with an atomic number of 16 is what we need to identify.

Step 4: Verify and Summarize

Looking at the periodic table, the element with atomic number 16 is Sulfur.

Final Answer

The element with the electron configuration $1s^2 2s^2 2p^6 3s^2 3p^4$ is Sulfur.
