Chemistry Test#1

Name the order of subshells: HINT* _<_<_<_ s<p<d<f
Write out the electronic configuration, including the subshells: 1s2,2s2,2p6,3s2,3p6,4s2, 3d10,4p6,5s2,4d10,5p6 6s2,4f14,5d10,6p6,7s2, 5f14,6d10,7p6
What is Group 1 called? Alkaline Metals
What is Group 2 called? Alkaline Earth Metals
What is Atomic Radius? The distance from the nucleus to the outermost electron shell. Atomic radius (distance) increases down a group and across a period.
What is Ionization Energy? The minimum energy required to remove one electron from the outer shell. Ionization decreases down a group and increases across a period.
What is Electronegativity? The ability of an atom to attract electrons. Elements closer to completing their valance shells are more electronegative. Electronegativity decreases down a group and increases across a period.
Which group is considered to have no electronegativity? Noble Gases, Group 7 & 8
What is Metallic Character? The tendency to lose electrons instead of gaining them. Elements become less metallic as you move along a period.
