chem periodic trends

test on 12/4/14

what is group one on the periodic table called alkali metals
what is group two on the periodic table called alkaline earth metals
what are groups 3-12 called transition metals
what is the metalloid in group 13 boron
is aluminum a metalloid no
is polonium a metalloid no
what are the lanthanide and actinide series called inner transition metals
what is group 17 called halogens
what is group 18 called noble gases
is hydrogen an alkali metal? no
what is the trend for reactivity for metals increases to the left and down
what is the trend for reactivity in nonmetals increases up and to the right
why do families have similar chemical reactivity similar valence electrons within a group results in similar chemical properties
what is periodicity or the periodic law when elements are arranged in order of increasing atomic number, elements with similar properties appear at regular intervals
what is the most reactive metal francium
what is the most reactive nonmetal fluorine
what is shielding core energy levels block the attraction between the nucleus and the outermost energy level
what is repulsion electrons in the inner shells repel each other
what is the periodic trend for atomic radius increases down and to the left
what is atomic radius size of the atom, 1/2 distance between the uncle of identical atoms bonded together
why is atomic radius larger as you go down a group higher energy levels have larger orbitals
why is atomic radius smaller to the right of a period increased nuclear charge without additional shielding pulls electrons in tighter (greater effective nuclear charge)
what is ionic radii size of an ion in an ionic solid
what is a cation ion with a positive charge due to a loss of electron(s)
what is an anion ion with a negative charge due to the gain of electron(s)
are cations larger or smaller than their neutral atom smaller than neutral atom
are anions larger or smaller than their neutral atom larger
do cations have an increased or decreased effective nuclear charge and why increased, same number of protons with fewer electrons
do anions have an increased or decreased effective nuclear charge and why decreased, same number of protons with more electrons means lower effective nuclear charge
what is the trend of ionic radii increase down and to the left
what is electronegativity measure of the ability of an atom in a chemical compound to attract electrons
what is the trend of electronegativity increases up and to the right
why does electronegativity increase up less shielding in smaller atoms
why does electronegativity increase to the right more protons pulling on the same energy level, no additional shielding
what is first ionization energy energy required to remove one electron from a neutral atom
what is the trend of ionization energy increases up and to the right
why is ionization energy trend opposite of atomic radius trend in small atoms, electrons are close to the nucleus where the attraction is stronger
why are there small jumps (higher first ionization energies in some elements than others) within each group stable electron configurations require more energy to remove electrons (half full sub levels, full sub levels)
why does ionization energy increase across a period greater effective nuclear charge (more protons pulling on the same energy level)
why does ionization energy decrease down a group more shielding, so the farther the electrons get from the nucleus, the less energy it takes to remove them
who is the father of the periodic table mendeleev
how was mendeleevs periodic table organized in order of increasing atomic mass
how is moseys periodic table organized in order of increasing atomic number
who invented the periodic table we use today moseley
what is the most reactive type of metal alkali metals
what are most of the elements on the periodic table metals
what is the chemical reactivity of noble gases no reactivity
what is the electronegativity for helium, neon, argon no electronegativity for the first three noble gases
in which state are most metals and what is the other most are solids, but one is a liquid; mercury
who developed electronegativity linus paulong
which element are all electronegativity values relative to fluorine (4.0)the most electronegative element
how to use electronegativity scale find difference: less than 1.7 is covalent bond, greater than 1.7 is ionic bond
in which state is ionization energy measured the gaseous state (kJ/mol)
how many elements are liquids at room temperature (25*C) 2; mercury and bromine
