Final answer:
The characteristics of metals include high electrical conductivity and ductility.
Step-by-step explanation:
Metals have several characteristics that differentiate them from other types of elements. Some of these characteristics include:
- High electrical conductivity: Metals are good conductors of electricity because their atoms have loosely held electrons that can move freely.
- Ductility: Metals are ductile, which means they can be stretched into thin wires without breaking.
Based on these characteristics, the correct options from the given choices are:
- a) High electrical conductivity
- c) Ductility
