Modern Periodic Table 4 New elements have been added to the periodic table in 2016! Elements are still being hunted!

Element 113 Discoverers: RIKEN Nishina Center for Accelerator-Based Science (Japan) proposed the name nihonium  Proposed symbol Nh. Nihon is one of the two ways to say “Japan” in Japanese, and literally mean “the Land of Rising Sun”. The name is proposed to make a direct connection to the nation where the element was discovered

Element 115 Discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) Proposed name is moscovium  Proposed symbol Mc  Moscovium is in recognition of the Moscow region and honors the ancient Russian land that is the home of the Joint Institute for Nuclear Research

Element 117 Discoverers: Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA). Proposed name tennessine Proposed symbol Ts Tennessine is in recognition of the contribution of the Tennessee region including the production and chemical separation of unique actinide target materials for superheavy element

Element 118 Discoverers: Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) Proposed the name oganesson  Proposed symbol Og Honoring a scientist and recognizes Professor Yuri Oganessian (born 1933) for his pioneering discovery of superheavy elements and significant advances in the nuclear physics

Wrap-UP Newly discovered elements can be named after: (a) a mythological concept/character or astronomical object (b) a mineral or similar substance, (c) a place, or geographical region, (d) a property of the element, or (e) a scientist. On your paper create a new Element! Include: Name, Atomic #, Mass, Properties

Family 8 Family Name: Noble Gas Valence Electrons: 8 Ion forming: None Classification: Nonmetals Properties: Most stable elements

Color in your PT

Periodic Table Families You will receive a set of cards. You will follow the instructions on the WORKSHEET! Fill in the worksheet as you go. When you’re done make an observation about the radius of atoms on pg 54 Try to determine the trend/pattern for atomic radius from the cards.

PG 54: Electron Configuration Families (columns) get names. Periods (rows) get numbers. Number your periodic table by rows. These are ENERGY LEVELS We can further divide the periodic table into 4 sections or SUBLEVELS In you groups come up with 4 blocks on the periodic table- think about properties!

Sublevels Sublevels describe the shape of atoms in 3D space. Used to predict bonding We divide the PT into S, P, D, F, Sublevels

Sublevels Color your PT you just numbered

Orbitals Orbitals: within a subshell, the position or house for an electron. Where electrons reside There are always 2 electrons in 1 orbital. S block has ____ orbitals P block has ____ orbitals D block has ____ orbitals F block has ____ orbitals

3 minutes Create an anagram to help you remember the electron configuration sublevels and orbital #’s!

Metric Conversion with SigFigs Practice You will solve the problem on your white board. When you are done stand up so your group members know you’re done. When everyone is standing compare answers. Coach and give tips once you’ve decided on an answer When you agree on an answer and everyone understands take a seat.
