4.6 Electron Configurations Flashcards
What are the three basic rules of electron configuration?
- electrons occupy the lowest energy orbital that is available
- electrons in the same subshell occupy available orbitals single prior to pairing up
- there can be no more than two electrons in any given orbital
What are the noble gases?
elements in the last column of the periodic table
What are diamagnetic atoms?
atom that has all of its electrons spin-paired
What are paramagnetic atoms?
atom that has at least one of its electron not spin-paired
What is the period on the periodic table?
horizontal row
What is a group or family on the periodic table?
vertical column
What is an ion?
atom that has a net charge
What does it mean to be isoelectronic?
atoms or ions that have the same number of electrons and therefore the same electron configuration
Which direction on the periodic table do we move if an atom becomes anionic? Cationic?
anionic = right
cationic = left
What is unique about the transition metals when losing electrons?
will lose from the s subshell prior to the d electrons
