Periodic Table Vocab & concepts practice Play the powerpoint and try to answer the questions
vertical column in the periodic table Group or family
Properties recur at regular intervals when elements are arranged in order of increasing atomic number. periodic law
type of element that is a good conductor of heat and electric current metal
type of element characterized by the presence of electrons in the d orbital transition metal
one-half the distance between the nuclei of two atoms when the atoms are joined Atomic radius
subatomic particles that are transferred to form positive and negative ions electrons
ability of an atom to attract electrons when the atom is in a compound electronegativity
energy required to remove an electron from an atom Ionization energy
The modern periodic table is arranged in order of increasing Atomic number
arranged the elements according to atomic mass Medeleev
atomic number of an element is the total number of protons
the electron configurations of the noble gases Complete outer energy level Octet Full valence shell
Describe and explain the trend in atomic radius from top to bottom within a group AR increasing Increasing numbers of occupied energy levels How does this affect ionization energy and electronegativity?
Describe and explain the trend in atomic radius from left to right within a period AR decreasing Increased charge in the nucleus results in stronger attraction for electrons How does this affect ionization energy and electronegativity?
the energy required to remove an electron from an atom Ionization energy
Determine the group and period location give the type of element and a characteristic property (only outer shell provided): 2s1 3s2 3p5 ... 5s24d6 2s22p6
