Question

what element is represented in the orbital diagram below?

Explanation:

Step1: Calculate the total number of electrons

Count the electrons in each orbital: \(1s^2\) has \(2\) electrons, \(2s^2\) has \(2\) electrons, and \(2p^6\) has \(6\) electrons.

$$2 + 2+6=10$$

Step2: Determine the element based on atomic number

The number of electrons in a neutral atom is equal to its atomic number. An element with atomic number \(10\) is Neon. But since Neon is not in the options, re - check the problem. Wait, maybe a mis - read: if we assume it's a typo and the user is referring to the electron - filling (the sum of electrons gives the atomic number). Let's check each option:

• Boron (\(B\)): Atomic number \(5\), electron configuration \(1s^22s^22p^1\)
• Nitrogen (\(N\)): Atomic number \(7\), electron configuration \(1s^22s^22p^3\)
• Fluorine (\(F\)): Atomic number \(9\), electron configuration \(1s^22s^22p^5\)
• Lithium (\(Li\)): Atomic number \(3\), electron configuration \(1s^22s^1\)

Wait, there is a mistake in the problem statement. If we assume that the sum of electrons (from the orbital diagram labels \(1s^22s^22p^6\)) is \(10\) (Neon), but if we consider that maybe the user intended to write \(2p^5\) (a common mis - label in diagrams). If \(1s^22s^22p^5\), then the number of electrons is \(2 + 2+5 = 9\).

Answer:

Fluorine
