Question

what atom is this? sulfur, z = 16 chlorine, z = 17 neon, z = 10 nitrogen, z = 7

Explanation:

Step1: Count the electrons

Count the number of electrons in each orbital.

• \(1s\): \(2\) electrons
• \(2s\): \(2\) electrons
• \(2p\): \(6\) electrons
• \(3s\): \(2\) electrons
• \(3p\): \(4\) electrons

Sum them up: \(2 + 2+6 + 2+4=16\) electrons.

Step2: Relate electrons to atomic number

In a neutral atom, the number of electrons (\(e^-\)) is equal to the atomic number (\(Z\)). Since \(e^- = 16\), \(Z = 16\).

Answer:

Sulfur, \(z = 16\)
