What are the general properties of metals?

Metals are poor conductors of heat and electricity.

Metals are always brittle and dull.

Metals have low density and are non-malleable.

Metals are good conductors of heat and electricity, malleable, ductile, lustrous, and have high density.

what are general properties of nonmetals

Nonmetals are generally poor conductors, dull, unmalleable

Nonmetals tend to lose electrons easily.

Nonmetals always exist as solids at room temperature.

Nonmetals are excellent conductors of electricity.

what are general properties of metalloids?

Metalloids are excellent conductors of electricity.

Metalloids have no luster and are always gases at room temperature.

Metalloids are semiconductors, have metallic luster, and exhibit mixed chemical properties.

Metalloids are always ductile and malleable.

what atoms are these and how many H2O

2 H atoms and 2 O atoms per H2O molecule.

1 H atom and 1 O atom per H2O molecule.

2 H atoms and 1 O atom per H2O molecule.

3 H atoms and 2 O atoms per H2O molecule.

what are the three bonds used to form compounds and mixtures

Ionic bonds, covalent bonds, metallic bonds

Dipole-dipole interactions

Van der Waals forces

Hydrogen bonds

what are metallic bonds

Metallic bonds involve the sharing of electrons between two metals or more

Metallic bonds are the result of ionic interactions between metals.

Metallic bonds are formed between non-metal atoms.

Metallic bonds are the attraction between metal ions and delocalized electrons.

what are covalent bonds

Covalent bonds are chemical bonds formed by the sharing of electron pairs between atoms that are only nonmetal

Covalent bonds only occur in ionic compounds.

Covalent bonds are weak attractions between molecules.

Covalent bonds are formed by the transfer of electrons between atoms.

what are ionic bonds

Ionic bonds occur only in metals and do not involve nonmetals.

Ionic bonds are formed by sharing electrons between atoms.

Ionic bonds are chemical bonds formed through the electrostatic attraction between metal and nonmetals

Ionic bonds are weak attractions between neutral molecules.

what is the difference between a mixture and a compound

mixtures are not chemically combined and compounds are, mixture have no definite ratio of elements while compounds do.

A mixture can only be made of solids, while a compound can be made of liquids and gases.

A mixture has a fixed composition, while a compound retains the properties of its components.

A mixture is always homogeneous, while a compound is always heterogeneous.

10.

what are ways to seperate a mixture

Sifting, crushing, blending

Heating, cooling, mixing

Dissolving, freezing, solidifying

Filtration, distillation, evaporation, centrifugation, magnetic separation.

11.

what is the difference between a pure substance and a mixed substance

A pure substance can be a mixture of different elements.

Mixed substances always have a uniform composition.

A pure substance contains multiple types of particles.

A pure substance has one type of atom while a mixed substance contains multiple types of particles.
