Question

the ability of a substance to be manipulated and pulled out or drawn into wires is called...
ductility
malleability
conductivity
luster
question 16
a substance that consists of one type of atom is called...
molecule
element
compound
mixture

Explanation:

First Question (The ability of a substance...):

To solve this, we recall the definitions of the terms:

• Ductility: Ability to be drawn into wires (matches the description).
• Malleability: Ability to be hammered into sheets (not about wires).
• Conductivity: Ability to conduct heat/electricity (not about shaping into wires).
• Luster: Shiny appearance (not related to shaping).

So the correct option is ductility.

Recall the definitions:

• Molecule: Group of atoms (can be same or different).
• Element: Substance with only one type of atom (matches the description).
• Compound: Substance with two or more different atoms bonded.
• Mixture: Combination of substances (not a single type of atom).

So the correct option is element.

Answer:

A. ductility

Question 16 (A substance that consists...):
