The A group elements of the periodic Table
The B group elements of the periodic table
elements in which electrons are beings added to the f orbitals
-the outermost electrons in an elements orbitals. ( Can only be S or P orbitals)
What happens when you add electrons to the the S or P orbitals? D or F orbitals?
S or P Electrons being added usually causes dramatic changes in the physical and chemical properties. Adding D or F electrons usually has a smaller effect on properties.
What kind of physical properties show periodic variations?
Melting points, boiling points, and atomic volumes
Effective Nuclear Charge- Zeff
the nuclear charge experienced by the outer most electrons of an atom; the actual nuclear charge minus the effects of shielding due to inner shell electrons
the radius of an atom
electrons in filled sets of s and p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus; also called the screening effect
Atoms become increasingly smaller due to increasing effective nuclear charges even though more electron are being added in which direction on the periodic table?
as we move across the periodic table
as shells are being added to shells further from the nucleus, what happens to the atomic radii from top to bottom on the periodic table? across the periodic table?
First Ionization Energy (IE1)
the minimum amount of En required to remove the most loosely bound electron from an isolated gaseous atom to form an ion with a 1+ charge
Second ionization Energy (IE2)
the amount of En required to remove the second electron
Electron Affinity (EA)
the En change when an electron is added to an isolated gaseous atom to form an ion with a 1- charge
having the same number of electrons
Transition Series (4)
1st transition series- 4s and 3d orbitals occupied
