Problem: The shape of the methane molecule is called__________.

We’re being asked to determine the shape of methane (CH₄). The possible molecular shapes are:

To do so, we first need to draw a Lewis structure for CH₄. For this, we need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the shape of the molecule.
