Radius and Isoelectronics
Which direction on the periodic table will result in LOWER atomic radius?
What is up and to the right?
Which group has the HIGHEST first ionization energy?
What is Group 18 (Noble Gases)?
Name a general characteristic of metals
What is mostly solids at room temp, shiny, good conductors, malleable, or form cations?
Which element has the smallest atomic radius?
What is Helium (He)?
Which group has the HIGHEST electron affinity?
What is Group 17 (Halogens)?
Name a general characteristic of nonmetals
What is any state at room temp, dull, insulators, brittle as solids, form anions, or low density?
Which of the following elements create an isoelectronic series with Kr?
Br+, Rb-, Se2-, Cl-
What is Se2-?
Which direction on the periodic table will result in MORE metallic characteristics?
What is down and to the left?
Why do nonmetals form anions?
Arrange the following three species in order of increasing ionic radius: P³⁻, S²⁻, Cl⁻
What is Cl⁻ < S²⁻ < P³⁻?
This Group 2 element has a positive (unfavorable) electron affinity because any incoming electron is forced into a higher-energy p-subshell, altering the expected r² boundary in Coulomb's Law.
What is Beryllium (or Magnesium)?
Electronegativity generally increases going right across a period, but which group, other than Noble Gases, are usually exceptions?
What is Group 2 and 12
While Zeff plays a massive role across a period, this is the primary reason atomic radius increases dramatically down a group
What is the distance between the nucleus and valence electrons (r)?
Why are the noble gases (Group 18) referred to as "inert gases"?
