DescriptionTerm
Series of fifteen metallic elements beginning with atomic number 57 & ending with lutetium (atomic number 71) in the periodic table/almost all have 4f electron shell
Each of 2 or more different physical forms in which an element can exist/carbon has variations of charcoal, graphite, diamond, & buckminsterfullerines (buckyballs)
Measure of the tendency of an atom to attract a bonding pair of electrons/usually measured on Pauling scale from 0-4/fluorine has highest value
Created from dyes extracted from lichens which are absorbed onto filter paper/used to indicate pH/first used in 1300 in Spain/blue turns red for acids & red turns blue for bases
Each of 2 or more forms of same element/contain equal numbers of protons but different numbers of neutrons in their nuclei/differ in atomic mass but not chemical properties
Substances that can donate protons or form covalent bonds with electron pairs/types named for Bronsted, Lewis, & Arrhenius/has pH below 7
Subatomic particles with 'flavors' of up, down, bottom, top, strange, & charm/named by Gell-Mann from Joyce's Finnegan's Wake/elementary fermion with spin -1/2
Compound with the formula C20 H14 O4/used to indicate pH/turns colorless in acids & pink in bases
Elements (boron, germanium, silicon, arsenic, antimony, & tellurium) whose properties are intermediate between those of metals and solid nonmetals/very important as semiconductors
Number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
Chemical compound that changes color & structure when exposed to certain conditions/used for chemical tests/includes phenolphthalein, litmus, methyl orange, thymol blue,...
DescriptionTerm
Series of fifteen metallic elements beginning with atomic number 89 & ending with lawrencium (atomic number 103) in the periodic table/almost all have 5f electron shell
Approximately equivalent to the number of protons and neutrons in the atom/is an average due to various isotopes
Highly reactive metals from Group 1 that include lithium, sodium, potassium, rubidium, & cesium/have 1 valence electron & oxidation state of +1
Group 18 elements/very low reactivity/includes helium, neon, argon, kyrpton, xenon, & radon/have 8 valence electrons/can be made to react in extreme conditions
Substances that can accept protons or donate electron pairs/types named for Bronsted, Lewis, & Arrhenius/has pH above 7
Group of chemically similar metallic elements comprising the lanthanide series and (usually) scandium and yttrium/tend to occur together in nature & are difficult to separate
Highly reactive non-metals from Group 17 that include fluorine, chlorine, bromine, iodine, & astatine/have 7 valence electrons & oxidation state of -1
Block of metals in periodic table that include iron, copper, nickel, & many others/have varying numbers of valence electrons/range from Group 3 to Group 8
Ionic compound which along with water is formed by the neutralization reaction of an acid & a base
Metals from Group 2 that include beryllium, magnesium, calcium, strontium, barium, and radium/have 2 valence electrons & oxidation state of +2
