General Chemistry

Atom

Smallest particle

Electron

A negative charged part of the atom

Proton

A positive charged part of the atom

Neutron

An 0 charged part of the atom

BEC

Bose Einstein condensate

Pure substance

One of the 2 major classification of matter, and this derives to the element and compounds

Mixture

One of the two major classification of matter, and derives to two things, the heterogeneous and homogeneous

Elements and compounds

Derived from a major classification of matter called pure substance

Homogeneous and heterogeneous

Derived from a major classification of matter called mixture

Solid, liquid, gas, plasma and BEC

Are the 5 states of matter

Ionic bonds

occur between metals, losing electrons, and nonmetals, gaining electrons.

Covalent bond

the interatomic linkage that results from the sharing of an electron pair between two atoms.

Metallic bond

the way that metal atoms are kept together within a metal material.

Electron configuration

a symbolic notation of the manner in which the electrons of its atoms are distributed over different atomic orbitals.

Electronegativity

a measure of the tendency of an atom to attract a bonding pair of electrons.

Atomic mass

the total mass of one atom of the given element.

Atomic weight

The total weight of an atom

Atomic sublevel

The sublevels are represented by the letters s, p, d, and f.

Orbital

a three dimensional description of the most likely location of an electron around an atom.

Atomic number

The number of protons In a nucleus

Diatomic

consisting of two atoms.

Molecule

Consists of two similar atoms

Compounds

Consists of two or more different atoms

Ionic compounds

compounds made up of ions that form charged particles when an atom (or group of atoms) gains or loses electrons.

Covalent compounds

a molecule that is formed when two or more different atoms are connected with a covalent bond.

Physical properties

Can be observed through using your 5 senses example: sight, hearing, etc.

Chemical properties

a characteristic of a substance that may be observed when it participates in a chemical reaction.

Color

How objects absorb light or reflect light

Texture

A physical properties the way something feels when you touch it.

Odor

is a physical property that will be observed when a substance does not changes into another substance. The substance should remain the same.

Hardness

a material's ability to resist permanent indentation (plastic deformation).

Malleability

a solid to bend or be hammered into another shape without breaking.

Conductivity

It is a physical property because the identity of the substance used is not changed i.e. no change in chemical composition.

Ductility

ability to be stretched, pulled, or drawn into a thin wire or thread without breaking.

Magnetism

is a physical properties on the macro- level.

Solubility

the ability of a solute (usually a solid) to dissolve in a solvent (usually a liquid).

Viscosity

a liquid's resistance to flow.

Freezing point

the temperature at which a liquid changes to solid.

Specific heat

describes how much heat must be added to a particular substance to raise its temperature.

Density revisited

Density of a substance in unique to that substance

Reactivity

the ability of matter to combine chemically with other substances.

Chemical changes

the kind of matter changes and at least one new substance with new properties is formed.

Composition

the arrangement, type, and ratio of atoms in molecules of chemical substances.

Kinetic energy

An energy the object has because of its motion.
