what are periodic trends
observable patterns in the properties of an element that are dependent on its position in the periodic table
which properties can be identified using periodic trends
electronegativity, atomic radius, ionzation energy, reactivity, and electron affinity
atomic radius definition
describing the distance between an atom’s nucleus and its outermost shell
describing the distance between an atom’s nucleus and its outermost shell
atomic radius
electronegativity
a property that measures the tendency of an atom to attract electrons to form a bond
a property that measures the tendency of an atom to attract electrons to form a bond
electronegativity
ionization energy
the minimum amount of energy required to restore an electron from a neutral atom’s outermost electron shell in the gaseous phase
the minimum amount of energy required to restore an electron from a neutral atom’s outermost electron shell in the gaseous phase
ionization energy
electron affinity
a property describing the tendency of a neutral atom to gain an electron in order to form a negative ion
a property describing the tendency of a neutral atom to gain an electron in order to form a negative ion
electron affinity
groups
vertical, determine similar properties same valence electron number
periods
horizontal, same valence electrons in the same energy levels
isotopes
forms of an element w different number of neutrons and masses
orbitals
s, p, d, f, represent different locations in the space that electrons can occupy
orbital letters
s, p, d, f
