Question

The Lewis dot diagram for an unidentified element is shown below.

Which element could X represent?
A. iron
B. chlorine
C. silicon
D. oxygen

Answer 1

• D. Oxygen.

Step-by-step explanation:

What is Lewis dot diagram?

Lewis dot diagram also known as electron -dot diagram represents the number of valence electron of atoms within a molecule.

Gilbert Lewis is the creator of the Lewis dot structure.

Lewis proposed a model for the role of electrons, particularly valence electrons, in 1916. This included the creation of electron dot diagrams or Lewis structures.

Electronic configuration of oxygen is
`\rm \underline{ 1s^2 \: 2s^2 \: 2p^4}`

Since oxygen has six valence electrons so, six electrons are drawn around oxygen atom.

In the given question there are also 6 electrons around the element X.

Therefore, The required answer will be Oxygen.
