Nonmetals
how can you tell if an element is a non metal
look at what side of the periodic table its on
is a metal brittle, malleable,or both
malleable
Do metalloids cross properties with metals and nonmetals?
yes
How many elements does the periodic table have.
118
witch rare earth metal is (Y)
Yttrium
Give the physical and chemical properties of metals and non-metals
what side is the metals on the periodic table
Left side
what are 3 fact about metalloids
1.Brittle
2. Semiconductor
3.Shinny
what is the periodic table
a tabular array of the chemical elements organized by atomic number,
What are rare earth metals
a group of metallic elements.
What is (Br) on the periodic table
Bromine
what are metals
metals are a class of a substances characterized by high electrical and thermal conductivity
what is the definition of metalloids
Metalloids can be defined as chemical elements whose physical and chemical properties fall in between the metal and non-metal categorie
what side is the nonmetals on the periodic table?
Right side
What are some properties of rare earth metals
1.magnetic
2. electrical
3.luminescent
what is the definition of nonmetals
what is the definition of metals
a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
what are metalloids ?
a chemical element that exhibits some metal and some nonmetal properties.
what does the IN stand for on the periodic table
Indium
how can you describe rare earth metals
luminescent, and electrical properties
A substance that is dull, brittle, and a nonconductor would be classified as a
nonmetal
do metals from below the surface
yes
Are metalloids rare
No, because While some metalloids like silicon are very abundant, making them not rare, others like tellurium are considered relatively rare elements, with abundance comparable to platinum, meaning that among metalloids, there is a spectrum of rarity depending on the specific element involved.
what is the periodic table used for..
The periodic table is used by scientists to organize and access information about chemical elements.
why are rare earth metals considered rare
rare earth metals which are considered "rare" because while not actually scarce in the Earth's crust, they are rarely found in concentrated deposits that make extraction commercially viable.
