Identify the type of solid from the description. Select from the following choices: metallic solid, network solid, molecular solid, ionic solid, or amorphous solid. a. This solid is ductile and conducts electricity.b. This solid is not conductive and has a low melting point.

Metallic solids have high melting point and also are good conductor of electricity and heat. Metallic solids are structured by metal atoms closely attached due to metallic bond. Example: Iron, copper & aluminum.

There are many forms of metals:

Malleable : They can be molded into materials like sheets i.e by hammering . They can be pressed into shape without being smashed or cracked
Ductile: They can be shaped into wires.
Solid: Most of the metals are solid are room temperature except mercury( which is a liquid).

Metallic solids are ductile and conducts electricity.

Option B. This solid is not conductive and has a low melting point.

Answer: Molecular solid

Molecular solids are consist of atoms or molecules. Molecular solids are not conductive and have low melting point. Example: sucrose

Reason behind not choosing other options:

Iconic solids: Consists of positive and negative icons. Iconic bonds have high melting point and are poor conductors. They are very brittle and hard in form Example: NaCl

Network solids: Consists of atoms connected by covalent bonds. Network solids have high melting point and non/poor conductors. Example: diamonds
