Metals
What is the chemical symbol for Gold?
Au
Nonmetals are generally poor conductors of heat and what else
Electricity
Metalloids share properties with both metals and which other type of element?
Non-metals
Name a halogen
Fluorine, Chlorine, Bromine, Iodine, Astatine, Tennessine
Name a Noble Gas
Helium, Neon, Argon, Krypton, Xenon, Radon, Oganesson (Not always counted)
What is the term for a metal's ability to be hammered or pressed into thin sheets without breaking or shattering?
Malleability
Which group of nonmetals, found in Group 18, are known for being chemically unreactive?
Noble gases
While metals are malleable, how do metalloids typically react when struck with a hammer?
They are brittle and break easily.
As you move down the halogen group, does reactivity increase or decrease?
Decreases
Which group of the periodic table contains the noble gases?
Group 18
What is the term for the property of a metal that allows it to be drawn into a thin wire?
Ductility
What is the name of the "salt-former" group of nonmetals that are highly reactive and have 7 electrons?
Halogens
Compared to metals, are metalloids better or worse conductors of electricity?
Worse
Which halogen is commonly added to water supplies and swimming pools as a disinfectant?
Chlorine
Noble gases are considered "inert." What does this mean?
They are chemically non-reactive.
What is the only metal that is not silver-colored or gray (not including gold)?
Copper
Nonmetals have high ionization energy. What does this mean when they interact with electrons?
They hold their electrons very tightly and do not lose them easily
What kind of compounds can metalloids form?
Both acidic and basic oxides/compounds.
Why are halogens highly reactive?
They have 7 valence electrons and only need to gain 1 electron to achieve a full shell.
What is the primary commercial source of helium?
Natural Gas
Which alloy, often composed of iron, nickel, and chromium, is specifically designed to resist oxidation and corrosion?
Stainless Steel
Which nonmetal has the highest known melting point of all elements
Carbon
In terms of ionization energy, where do metalloids fall compared to metals and nonmetals?
In between the values of metals and nonmetals
Which group number in the periodic table contains the halogens?
Group 17
Which noble gas can diffuse through rubber?
Helium
