Metal Physical Properties
lustrous (shiny)
good conductors of heat and electricity
high melting point
high density (heavy for their size)
malleable (can be hammered)
ductile (can be drawn into wires)
usually solid at room temperature (an exception is Mercury)
opaque as a thin sheet (can't see through metals)
metals are sonorous or make a bell-like sound when struck
Nonmetal Physical Properties
not lustrous (dull appearance)
poor conductors of heat and electricity
nonductile solids
brittle solids
may be solids, liquids or gases at room temperature
transparent as a thin sheet
nonmetals are not sonorous
These chemical elements are nonmetals.
The metalloids have properties of both metals and nonmetals.
The physical properties of hydrogen are closer to those of nonmetals. Hydrogen is a diatomic gas with low melting and boiling points, similar to other nonmetals. It does not exhibit typical metallic properties like high electrical conductivity or metallic luster.
An element that has properties of both metals and non-metals is called Metalloid. Example is Germanium.
Metals are located on the left side of the periodic table, nonmetals are on the right side, and metalloids are along the zig-zag line that separates metals and nonmetals. This classification is based on the physical and chemical properties of the elements.
These chemical elements are nonmetals.
nonmetals because hydrogen is a gas
Scientists arrange elements into metals, nonmetals, and metalloids based on their physical and chemical properties. Metals are typically good conductors of electricity, nonmetals are poor conductors, and metalloids have properties of both metals and nonmetals.
Metals on the periodic table are elements that are typically shiny, malleable, and good conductors of heat and electricity. Their properties differ from nonmetals and metalloids in that metals tend to be more ductile, have higher melting and boiling points, and are more reactive. Nonmetals, on the other hand, are typically brittle, poor conductors of heat and electricity, and have lower melting and boiling points. Metalloids have properties that are intermediate between metals and nonmetals.
Physical properties of metals include: luster, malleability, and ductility. Chemical properties include: forming cations, and reacting with nonmetals to form ionic compounds.
because metalloids usually have properties that are similar to metals and nonmetals
The metalloids have properties of both metals and nonmetals.
Most elements are classified as metals, nonmetals, or metalloids based on their physical and chemical properties. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally poor conductors and can be gases or brittle solids. Metalloids have properties of both metals and nonmetals.
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals
No, metalloids have properties of metals and nonmetals.
Elements are classified into metals, metalloids, and nonmetals based on their physical and chemical properties. Metals are typically shiny, conduct heat and electricity well, and are malleable. Metalloids have properties that are intermediate between metals and nonmetals. Nonmetals are usually dull in appearance and poor conductors of heat and electricity.
Metalloids have properties of both metals and nonmetals. They can conduct electricity like metals but are brittle like nonmetals. Some examples of metalloids are silicon and germanium.
