Matter and Its Properties
What are physical properties?
Any characteristic that you can observe without changing a material’s identity.
What elements are metals?
iron, copper, silver, mercury, lead, aluminum, gold, platinum, zinc, nickel and tin
Nonmetals are elements that have NO...?
Metallic Properties
What is nonmetal?
What is luster?
Luster describes how the mineral reflects light.
What are chemical properties?
Matter’s condition or physical property.
What are the physical properties of metals?
lustrous, malleable, ductile, good conductors of heat and electricity.
Metalloids are elements that have ?
Properties of metals and nonmetals.
What is halogen?
The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
What is ductility?
Ductility is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking.
What is density and how is it used to identify an unknown substance?
A substance’s mass per unit volume
Metals have the unique properties that include the ability to? 1,2,3
What are the physical properties of nonmetals and metalloids?
Nonmetals are generally dull or nonreflective and do not have a metallic luster.
What is a noble gas?
Group 8A of the periodic table are the noble gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
What is malleability?
The property of metals by which they can be beaten into thin sheets
How are physical properties used to identify a mineral?
hardness, density, luster, color, magnetism, strength, flexibility, malleability, ability to conduct heat or electricity, mass, weight, volume, viscosity, and freezing, melting, and boiling points.
How does the position of an element on the periodic table allow you to determine if the element is a metal?
Metals are grouped into blocks on the left and in the middle of the periodic table (groups 1-12, except hydrogen) and below the metalloids in groups 13-15
Where are nonmetals and metalloids on the periodic table?
nonmetals lie to the right of the zigzag line and metalloids form the narrow stair-step pattern between the metals and the nonmetals.
What is metalloid?
A metalloid is a chemical element that exhibits some metal and some nonmetal properties.
What is alkali metal?
any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
If an element does not have the chemical and physical properties of a metal, can it be called a metal?
NO; all metals have certain chemical and physical properties in common that make them distinct from nonmetals.
Name three elements that are alkaline earth metals.
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
What percentage of the human body is made up of oxygen?
65%
What is semiconductor?
Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics).
What is transition element?
Transition elements (also known as transition metals) are elements that have partially filled d orbitals. Their properties are transitional between highly reactive metallic elements of s-block which are ionic in nature and the elements of p-block which are covalent in nature.
