Al, Cl, Ga 2. IONIC RADIUS For each of the following sets of ions, rank them from smallest to largest ionic radius. a. Mg 2+, Si 4-, S 2-b. Mg 2+, Ca 2 ...
Explain in words and with a diagram why ionic radius of cations and anions is different from their atoms.
3. What trends do you notice for the atomic radii of Period 3? The atomic radius gets smaller as atomic number increases. 4. Explain why this trend occurs. Going from left to right across a period, the size gets smaller. Electrons are in the same energy level, but there is more nuclear charge (more protons). The increased charge pulls electrons ...
ATOMIC RADIUS 1. What trend in atomic radius do you see as you go down a group/family on the periodic table? 2. What causes this trend? 3. What trend in atomic radius do you see as you go across a period/row on the periodic table? 4. What causes this trend? 5. Circle the atom in each pair that has the largest atomic radius.
