Periodic Trends - Warmup Ca2+ and K+ each have 18 electrons around the nucleus. Which has a smaller radius and why?

Warmup - Overview of PT From memory, compare metals, metalloids, nonmetals (see samples at Station 8) and noble gases in terms of: Appearance State of matter Electrical conductivity Heat conductivity Malleability and ductility Atomic radius Ionization energy Electronegativity Electron configuration  

Periodic Trends – Warmup (Honors) 1. List in order of increasing atomic radius: Be, C, Li+, Ne, B3+, F-   2. List in order of decreasing ionization energy: Cs, Na, Ca, H+, K+, Fr

Periodic Trends – Warmup 1. List in order of increasing atomic radius: Li+ or Li, B3+ or B, F or F -  What general statement can be made from the above pattern(s)? 2. List in order of decreasing ionization energy: Cs, Na, Na+, K+, Why is there a different between the cation & its elemental form?
