- a The atomic radius is _______ going down a group because the principal energy level increases.
- b Always smaller than their atoms.
- c Distance from the center of an atom's nucleus to its outermost electron.
- d Tendency for atoms to attract electrons in a chemical bond.
- e elements that have characteristics of metals and nonmetals. Right side of stairstep- more of metal characteristics. Left side- more of nonmetal.
5 Multiple Choice Questions
- The atomic radius is ________ going across a period, because adding more protons= more of a pull, pulling electrons in closer.
- The electronegativity of an atom _______ down a group.
- Group IA, one electron in outer level, soft but very reactive.
- Group IIA elements, not as reactive as alkali metals, but still very reactive.
- The electronegativity of an atom _______ across a period.
