Nucleus
protons and neutrons
Atomic mass (A)
protons + neurtrons
Atomic number
number of protons
nuclides
same protons = same element
Isotope
same chemical properties, but different physical properties
Isotope eines Elements stehen an der gleichen Stelle im Periodensystem. Die Anzahl der Protonen im Kern ( Ordnungszahl) ist gleich, die Zahl der Neutronen variiert jedoch, sodass sich Isotope hinsichtlich ihrer Atommasse unterscheiden.
electron orbit
K: 2
L: 8
M 18
N: 32
outer orbit shell
valence
determines the chemical, electrical and thermal properties of the element
ion
electrons <> protons
electron excitation
gains energy and moves to higher energy outer shell
electronic radiation
emision, when excited electron drops back the inner shell with lower energy level
Binding energy E and atomic number Z of
Iodine?
Barium?
Tungsten?
Lead?
energy to remove the electron from the an atom
high, as Z=atomic number is high
high for electron in the inner shell, closer to the nucleus
