Are metals located mostly on the left, right, or middle of the periodic table?
The left side and middle (most of the table).
Most nonmetals are found on which side of the periodic table?
Right
Where on the periodic table are metalloids located?
Along a zigzag 'staircase' line between metals and nonmetals.
If an object's density is greater than water's, will it sink or float?
Sink
What is the smallest unit that makes up an element?
An atom
Name one physical property of metals.
Shiny/lustrous, conducts electricity, conducts heat, malleable, ductile, or high density.
Name a physical property of nonmetals.
Dull, poor conductors of heat/electricity, brittle, or often gases.
Metalloids have properties of which two types of elements?
Metals and Nonmetals
If an object's density is less than water's, will it sink or float?
Float
Name the three main categories elements are classified into by properties.
Metals, nonmetals, metalloids
What does it mean for a metal to be malleable?
It can be hammered or rolled into thin sheets without breaking.
Do nonmetals conduct electricity well or poorly?
Poorly- they are insulators.
Name a metalloid.
Silicon, boron, germanium, arsenic, tellurium, astatine or antimony.
What is the density of water?

An element that is shiny and conducts electricity is most likely a ___.
Metal
Which property allows metals to be drawn into wires?
Ductility
Many nonmetals exist as which state of matter at room temperature?
Gases (some are solids, like sulfur and carbon; only bromine is a liquid).
Name a way that metalloids are used in modern life.
Solar cells, detergents, batteries

Nonmetal
What metal is not solid at room temperature?
Mercury
Name one element that is a nonmetal.
Oxygen, nitrogen, hydrogen, carbon, sulfur, chlorine, etc.
What does 'semiconductor' mean?
It can conduct electricity under some conditions but not others — the basis for electronic devices.
What happens to an object whose density equals the density of the fluid it's in?
It hovers / neither sinks nor floats (neutral buoyancy).
Which category has some properties of both metals and nonmetals?
Metalloids
