MOD 17: Properties and Types of Metals

Element that is shiny, malleable, ductile, and a good conductor of heat and electricity?

• Metallic Bonding

• Metal

• Transition Element

• Non-metals

Occurs because some electrons move freely among a metal's positively charged ions, explains properties such as ductility and the ability to conduct electricity?

• Metals

• Non-metals

• Metallic Bonding

• Transition Element

Element, such as radium, whose nucleus breaks down and emits particles and energy?
