Ionization
What is the widest element
Fr
What is the formula for effeective nuclear charge, Zeff
Zeff = Z - S
What is the Zeff trend
Increases left to right, no vertical trend
define cation, does it lose or gain electrons
positive ion, loses electrons
Define ionization energy
The energy it costs to remove an electron
Define Z
Nuclear charge
What determines bond length
size of the atoms
define anion, does it lose or gain electrons
negatively charged, gains electrons
Define electron affinity
the energy associated with gaining an electron
Define S
Shielding or core electrons
what is an isoelectronic series
all have the same number of electrons
Which is a metal
cation
What is the ionization energy trend
Top to bottom, right to left
Does a more positive Zeff mean electrons are pulled towards the nucleus more or less
More
is ionization energy usually positive or negative
positive
is a cation bigger or smaller than the same element in its neutral state
smaller
What is the electron affinity trend
increases bottom to top towards Cl, left to right
Explain Zeff
How attracted the outermost electrons are to the nucleus, taking into account their repulsion fron the other core electrons
what happens to ionization energy if you remove more than one electron
it goes up
is an anion bigger or smaller than the same element in its neutral state
bigger
