Download Chemical Bond – a force that holds two atoms together, the bond

Chemical Bond – a force that holds two atoms
together, the bond could be between two elements
that are the same element or different elements.
Ionic Bond – an electrostatic force between two
different atomic elements (atomic nonmetal and
an atomic metal) in which the atomic nonmetal
steals the available electron/s for bonding from the
atomic metal, thus creating a positive cation on
the atomic metal, and a negative anion from
atomic non metal.
Cation – an atom with a positive charge because it
gives or loses an electron to another element.
Anion – an atom with a negative charge because it
receives or steals an electron
Oxidation Number – the charge of a monoatomic
ion
Monoatomic ion – a one-atom ion
Polyatomic ion – an ion with more than one atom
bonded together
Metallic Bond – is the attraction of a metallic
cation for delocalized electrons; electrons are not
localized to one metallic atom.
Delocalized Electrons – electrons that freely move
from one metallic atom to another metallic atom.
Covalent Bond – a chemical bond between two
different atomic elements (atomic nonmetal and
an atomic nonmetal) where two atoms share the
electrons available for bonding, or valence
electrons
Molecule – a structure that is made up of two or
more atoms bonded covalently.
Lewis Structures – they are electron dot-diagrams
that show how electrons are arranged in
molecules.
Covalent Single Bond – a covalent bond in which 2
electrons are shared between two nonmetal atoms.
Covalent Double Bond – a covalent bond in which
4 electrons are shared between two nonmetal
atoms.
Triple Bond – a covalent bond in which 6
electrons are shared between two atoms.
Polar Covalent Bond – it is an unequal sharing of
electrons between two different kind of element
atoms; due to different electronegativites.
Non-Polar Covalent Bond – it is an unequal
sharing of electrons between two different kind of
element atoms; due to different electronegativites;
but gets cancelled out because there is the same
bond with the same element’s atom on the
opposite side of the center atom, thus cancelling
out the unequal force of the sharing of electrons.
Avogadro’s number – it is number of anything
that is equal to 6.02 x 1023
602,000,000,000,000,000,000,000
Mole – it is a unit used to measure the amount of a
substance in 6.02 x 1023 atoms of any substance
Molar Mass – the mass in grams of one mole of
any pure substance.
Molecular Formula – the actual number of atoms
of each element in one molecule or formula unit of
the substance.
