Test 1: Periotic Table & Electron Configuration Flashcards
Periodic means
repeating pattern
Periodic Table is really a
Repeating table: where elements which react similarly are grouped together and that reactivity tends to repeat itself.
On the periodic table, all of the atoms in the middle block are known as
Transition metals or Transition elements (although they are all metals).
On the periodic table, the block that is separated from the rest of the table and put down below is known as
the Inner Transition metals. This block actually belongs in the middle of the normal periodic table
The four major groupings on the periodic table
Metals
Non-metals
Metalloids
Noble gases
Metalloid properties are similar to both
metals and non metals
Properties of metals
malleable (can be hammered into a thin sheet), ductile (can be drawn into a thin wire), lustrous (shiny, reflective), and they conduct Electricity and heat.
Properties of nonmetals
tend to be brittle in their solid forms, and poor conductors of both electricity and heat.
Properties of metalloids
Topside: nonmetals with some properties of metals
Bottom-side: metals with some properties of nonmetals.
the only particles on the surface that interact with the surroundings of an atom are
electrons
Valence electrons dictate
how atoms interact with other atoms, which influences physical properties and chemical reactivity of the elements as a whole.
Electrons are confined to discrete areas called
orbitals
it is natural for each electron to fall into the ___ energy orbital possible
lowest
electrons fit into discrete energy levels known as
shells
Shells contain
subshells
