Which of the following is true about metallic solids? Question 12 options: Metallic solids do not conduct electricity Metal atoms arrange in a regular, repeating pattern known as a crystal lattice Metal atoms do not exhibit a crystal lattice

To determine which statement is true about metallic solids, let's analyze each option step by step:

1. Metallic solids do not conduct electricity

   • This statement is false. Metallic solids are known for their ability to conduct electricity due to the presence of free-moving electrons within the metal lattice.

2. Metal atoms arrange in a regular, repeating pattern known as a crystal lattice

   • This statement is true. Metallic solids have a structure where metal atoms are arranged in a regular, repeating pattern, forming a crystal lattice. This arrangement contributes to the properties of metals, such as malleability and electrical conductivity.

3. Metal atoms do not exhibit a crystal lattice

   • This statement is false. As mentioned in the previous analysis, metal atoms do exhibit a crystal lattice structure.

Therefore, the correct answer is:

Metal atoms arrange in a regular, repeating pattern known as a crystal lattice
