as you move from left to right across the second period of the periodic table

• the atomic mass decreases

• the ionization energy increases

• the atomic radii increases

• the electronegativity decreases

an element in which the outermost s and o sublevels are completely filled

• inner transition metals

• metalloids

• transition metals

• noble gases

the vertical columns of the periodic table are called

• groups

• rows

• periods

• sublevels

which of the following atoms would you expect to have the largest atomic radius

• Na

• P

• Ar

• Al

The alkali metals do not include

• Na

• Li

• Rb

• Ca

The energy needed to remove an electron from a gaseous atom

• Electronegativity

• Electron affinity

• ionization energy

• atomic radius

Based on what property did Mendeleev organize his periodic table

• number of neutrons

• atomic mass

• atomic number

• number of photons

which of the following has the smallest ionic radius

Electronegativity

• is the energy change that accompanies the loss of an electron from a gaseous atom

• generally decreases from left to right across a period

• generally decreases as you move down a group

• is generally higher for metals than nonmetals

the tendency of an atom to attract electrons to itself when it is chemically combined with another element

• electronegativity

• elegy or ionization

• bond ionization energy

• ionization energy
