Electron Configuration Flashcards
Which subatomic particles are inside of the nucleus?
protons and neutrons
what is the proton charge?
positive
what is the neutron charge?
neutral
electron charge and placement
electron cloud, negative
which part of an electron makes up the mass? volume?
mass- nucleus (dense)
volume- electron cloud
Isotope
number of neutrons changes
in a neutral atom which two particles have an equal amount?
protons and electrons
anion
negative ion (gains electrons)
cation
positive ion (losing electrons)
Subshells, orbitals, and electrons
s,1,2
p,3,6
d,5,10
f,7,14
Where do you remove electrons from
Highest number in highest subshell
which elements round up
any at d4 or d9
Isoelectronic
2 atoms of different elements with the same electron configuration (like Ne and Na+)
Coulumb’ law formula
F=q/r^2
(F= force of attraction, q=#protons, r^2=energy level)
Ionization energy
energy required to remove an electron
relation between force of attraction and ionization energy
greater F=greater Ionization energy
Steps to determining which element has greater ionization energy
1) compare each atom in terms of which Valence electron is closer to the nucleus
2)if valence electrons are in the same energy level, look at number of protons (less protons=higher IE)
on which energy level does it take the most energy to remove an electron
the lowest (closest to nucleus)
how do you identify an isotope from a mass spec reading
find the number of neutrons in the largest peak, subtract atomic # from mass
