What are metalled and non-metalled roads?
Metals are elements that are typically lustrous (shiny), malleable, ductile (can be made into wires) and are usually good conductors of heat and electricity. Except for the element mercury metals are solid at room temperature. Most metal ions have a positive charge. Nonmetals are typically dull in color and brittle when solid and are usually poor conductors of heat and electricity (graphite, a form of carbon is an exception to this as it conducts electricity). Some of the nonmetals are gasses at room temperature, some are solids, one (bromine) is a liquid. Unlike metals, some of the nonmetals exist as distinct molecules. Nonmetals generally form negative ions. Metalloids have properties of both metals and nonmetals and do not fit neatly into either category. They are often lustrous like metals but tend to be brittle like nonmetals. metalloids are classified as semiconductors as they have a moderate ability to conduct heat and electricity. They are solid at room temperature..
What civil rights activists used interstate buses to protest segregation at terminals?

What was the result of the integration of Montgomery buses?
African American integrate its buses.
What were some of the tactics used by the civil rights activists to bring out these changes?
Encouraging people, i.e. to boycott buses.
What did blacks hope to gain by boycotting the buses in Montgomery Alabama?
They hoped to use economic pressure to end segregation on the buses.
How are metals used in chemistry?
Metals are used in chemistry for coating of some metalloids and nonmetals
What is the most reactive group of a metals and nonmetals?
Metals: alkaline metals Nonmetals: halogens
How are metalloids differents from metals and nonmetals?
because metalloids usually have properties that are similar to metals and nonmetals
What are uses of nonmetals?
Non metals are used as insulators (poor conductors)
What kind of bonds do metals and nonmetals form?
Metals and nonmetals form ionic bonds.
Elements can be classified as metals semi metals non metals?
Metals are good conductors of heat and electricity, while nonmetals are poor conductors. Metalloids have properties that are intermediate between metals and nonmetals.
What is an element that has characteristics of both metals and nonmetals?
An element that has characteristics of both metals and nonmetals is a metalloid.
Can color or be used to distinguish metals from non metals?
Yes, color can be used to distinguish metals from nonmetals. Generally, metals have a characteristic metallic luster or shine, while nonmetals can appear dull or have a wide range of colors depending on the element. Conductivity and malleability are other properties that can help distinguish between metals and nonmetals.
What have the qualities of both metals and nonmetals?
They are metals.
Do metaloids contain metals and nonmetals?
Metalloids do not contain either metals or nonmetals. They are elements that have properties of both metals and metalloids, and are found between the metals and nonmetals on the periodic table.
What are three types of categories found in the periodic table?
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
Do the elements go from metals to nonmetals or nonmetals to metals?
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.
