Today in ScienceYou will Need:•Pencil, Periodic Table•Power Notes – Atomic Structure– 2 page 4sides- Picked up yesterday(Wed.)•Atomic Structure – Application Part 2 –Bookshelf-1 page 2 sides
Review•Which subatomic particle in the atom has apositive charge?•Which subatomic particles are found in thenucleus of the atom?•Of the three major subatomic particle in theatom, which is the smallest?•Why are atoms found on the periodic tableneutral….why do they not have any charge?•Which scientist found that the atom wasmostly empty space?
Review•Which subatomic particle “IDENTIFIES”which element it represents?•Which subatomic particle is neutrallycharged and found in the nucleus?•Which scientist named his model the “PlumPudding Model”?•What does the atomic number on theperiodic table represent about the atomicstructure?
Review•When an atom has more electrons than protons ithas what charge?•What do you call an atom that does not have thesame number of electrons and protons?• Protium, Deuterium and Tritium are all forms ofHydrogen. How do we know they are all Hydrogen?•When thee are different forms of the sameelement with different amounts of neutrons whatdo we call them?
Review•Who was the scientist that created the 1st ModernAtomic Theory?• What particles does the Atomic Mass representon the Periodic Table?• How many protons does Fluorine have?• How many electrons does Calcium have if it is aneutral atom?•What is the chemical symbol for GOLD?• Would I add, subtract, multiply or divide to findthe volume of a substance if I knew the mass anddensity?
Review•Slicing a piece of Sodium Chloride in half. Physicalor Chemical?• Decaying trash. Physical or Chemical?• How many neutrons are in the most commonform of Lithium?• Most of the MASS in the atom is found in whatpart?• The phase of matter dependends on what?• The most abundant form of matter in the universeis _______________?
All atoms found on the • Neutral – same # of protons(+)Periodic Table are and # of electrons(-)Isotope • Atoms of the same element with same number of protons and different number of neutrons. nucleus nucleus ProtonHydrogen has 3 naturaloccurring ISOTOPES:Protium, Deuterium and Protium nucleus DeuteriumTritium are Neutro All ROGEN have n l HYD use al Tritium a bec oton. r 1 p
Atomic MASS • On the Periodic Table represents a weighted average of the mass of all naturally occurring isotopes of each element. (based on mass and abundance of each isotope). • When atoms gain or lose electronsIONS they become charged. (number of protons (+) and electrons (-) particles are NOT EQUAL)REVIEW & REFLECT + -
Coloring the Periodic • Outline each box in the followingTable way: • Metalloids – in BLUE • Nonmetals – in ORANGE*Textbook pg 196-197 – Use the • Metals – in GREENkey
NONMETALS- gain electronsMETALS- lose electrons Metalloids
Atomic Structure • The ATOMIC NUMBER of anApplication element is the number of PROTONS Can also be # of electrons if in the center, nucleus of an atom. neutral • It is the PROTONS that IDENTIFY which element is on the periodic table. • NO TWO elements have the same ATOMIC NUMBER. (proton count) #2 – Ac tually 9 elemen ts that start wi th the Number of protons + neutrons letter “ C” Use your Periodic table to complete the application exercises. You may work as a group to answer the questions.
