Metals are shiny because their outer electrons not attached to any particular atom but are free to wander throughout the material with little resistance. This is also what makes metals conductive. So when light shines on metal it sets these free electrons into vibration so instead of energy springing from atom to atom it's reemitted as visible light. However, nonmetals may not have this property and therefore aren't shiny.

What are the names of the major categories of elements on the periodic table?
The major categories of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are usually not shiny, brittle, and poor conductors. Metalloids share properties of both metals and nonmetals.
What are the three classes of group A elements?
The three classes of group A elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of electricity. Nonmetals are usually dull, brittle, and poor conductors of electricity. Metalloids have properties of both metals and nonmetals.
Is shiny a metal nonmetal or metalloid?
You can make almost anything shiny by polishing it.
What properties do metals generally share Nonmetals How does this relate to their location on the periodic table andor the type of ions they form?
Most are shiny.
Which type of elements are often dull brittle and poor conductors?
Nonmetals are often dull, brittle, and poor conductors of heat and electricity. Unlike metals, which are typically shiny and malleable, nonmetals tend to have a dull appearance and can break easily when subjected to stress. Common examples of nonmetals include sulfur, phosphorus, and carbon in certain forms.
Are physical properties of nonmetals shiny?
Nonmetals are generally not shiny. They tend to be dull.
Do nonmetals look shiny?
No. Nonmetals are dull, not lustrous.
What distinguishes nonmetals from metals?
metals are shiny and good conductors of heat and electricity. Nonmetals are dull and poor conductors of heat and electricity.
Shiny malleable ductile and generally conduct electricity and heat are qualities of what?
nonmetals
Does nonmetal have a luster?
Nonmetals typically do not have a luster. They have properties like dullness, low conductivity of heat and electricity, and fragility. Common examples of nonmetals include sulfur, oxygen, and nitrogen.
Which of the following is a property of nonmetals poor conductors of electric current very reactive with water malleable shiny?
Many - but not all - are poor conductors of electric current.
What are the names of the major categories of elements on the periodic table?
The major categories of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are usually not shiny, brittle, and poor conductors. Metalloids share properties of both metals and nonmetals.
What are the three main types of elements on the periodic table?
The three main types of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, conductive, and malleable. Nonmetals are typically dull, poor conductors, and brittle. Metalloids have properties that are between metals and nonmetals.
What are the three classes of group A elements?
The three classes of group A elements are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of electricity. Nonmetals are usually dull, brittle, and poor conductors of electricity. Metalloids have properties of both metals and nonmetals.
What are the 2 categories of elements?
Elements can be categorized into metals and nonmetals. Metals are typically shiny, malleable, and good conductors of electricity, while nonmetals are often dull in appearance, brittle, and poor conductors of electricity.
What are the three categories of elements?
Metals, non-metals and transition metals.
What are the different types of elements on the Periodic table?
The periodic table includes metals, nonmetals, and metalloids. Metals are typically shiny, ductile, and good conductors of electricity. Nonmetals are often dull, brittle, and poor conductors. Metalloids have properties of both metals and nonmetals.
