Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud In general, atomic radius decreases across a period and increases
Describe and explain the observed trends in atomic size, ionization energy, Proceeding down the groups of the periodic table, we find that cations of
In this periodic table, the relative sizes (not absolute - there are no measurements) are shown The sizes of the noble gas atoms (gray) can't really be
These periodic trends can clearly be seen in atomic radii, ionic radii, ionization energies and electronegativities These specific trends will be investigated
Check the Periodic Table to find out how many electrons each element actually has The atomic radius is a measure of the size of an atom The larger the
Write a letter to your friend explaining atomic radii, ionization energy and electronegativity Include an explanation of the trends for each as you move across
Atomic radius: a measure of an atom's size, using the distance from the centre of the nucleus to the outermost electron shell Effective nuclear charge (Zeff):
tions about atomic size, electronegativity, ionization energies, bonding, solubility, and reactivity In this activity you will look at a few periodic
