CLASSIFYING ATOMS MATTER BUILDING BLOCKS OF ALL MANKIND

CLASSIFYING ATOMS

MATTER BUILDING BLOCKS OF ALL MANKIND

Essential Standards 6. P. 2: Understand the structure, classifications and physical properties of matter.

Clarifying Objectives 6. P. 2. 1: Recognize that all matter is made up of atoms and atoms of the same element are alike, but different from the atoms of other elements.

ESSENTIAL QUESTIONS • WHAT IS AN ATOM? • WHAT IS AN ELEMENT?

MATTER • ALL GALAXIES, HUMANS, STARS, ANIMALS (ANYTHING) IS COMPOSED OF MATTER • EVERYTHING IS MADE OF MATTER • ATOMS ARE A TYPE OF MATTER • THE SMALLEST MATTER THAT EVERYTHING IS COMPOSED OF IS CALLED AN ATOM

PHYSICAL PROPERTIES OF MATTER • PHYSICAL PROPERTIES CAN BE • PHYSICAL PROPERTIES OF MATTER OBSERVED WITHOUT CHANGING THE IDENTITY OF THE ELEMENT ARE CHARACTERISTICS THAT BEEN FELT, MEASURED OR SEEN… • • • COLOR ODOR LUSTER CONDUCTIVITY HARDNESS MELTING POINT BOILING POINT DENSITY (M/V) MASS VOLUME WEIGHT LENGTH

CHEMICAL PROPERTIES OF MATTER • CHEMICAL PROPERTIES REFER TO AN ELEMENTS ABILITY TO CHANGE INTO A NEW SUBSTANCE • • FLAMMABILITY REACTIVITY

ATOMS • ALL LIFE STEMS FROM ATOMS • ATOMS ARE THE SMALLEST PARTICLES OF MATTER THAT HAS THE SAME CHEMICAL MAKEUP • ALL MATTER IS MADE UP OF ATOMS

ATOMS • NUCLEUS- MIDDLE OF THE ATOM CONTAINS THE PROTONS & NEUTRONS • PROTONS (+)POSITIVELY CHARGED PART OF THE ATOM LOCATED IN THE NUCLEUS • NEUTRONS (NO CHARGE)NEUTRAL PART OF THE ATOM LOCATED IN THE NUCLEUS • ELECTRONS (-) NEGATIVELY CHARGED LOCATED OUTSIDE THE VALENCE

ATOMS • ATOMS ARE TOO SMALL TO BE SEEN THROUGH A MICROSCOPE • IF YOU PUT BILLIONS OF THE SAME TYPE OF ATOM TOGETHER YOU GET AN ELEMENT

ESSENTIAL QUESTIONS • GET WITH A PARTNER AND ANSWER… • WHAT IS AN ATOM?

GROUPS OF ATOMS • ELEMENTS, MOLECULES &COMPOUNDS

ELEMENTS • AN ELEMENT IS A SUBSTANCE THAT IS MADE UP OF ONLY ONE KIND OF ATOM • THE ELEMENT OF IRON IS DIFFERENT FROM THE ELEMENT OF NICKEL BECAUSE THEIR ATOMS ARE DIFFERENT • ELEMENTS CAN’T BE BROKEN DOWN INTO SOMETHING SIMILAR

Elements There about 100 different kinds of elements known to mankind They are found on the Periodic Table Elements combine with each other to form Compounds

ELEMENTS • WHEN ELEMENTS COMBINE TO FORM COMPOUNDS, THEY CAN MAKE BOTH LIVING & NONLIVING ORGANISMS

MAKING AN ELEMENT • TO • ALL ATOMS MUST BE THE • ALL THE ATOMS THAT MAKE THE ELEMENT GOLD…. SAME (GOLD ATOMS) MAKE UP THE ELEMENT MUST HAVE THE SAME PHYSICAL & PROPERTIES CHEMICAL

ESSENTIAL QUESTIONS • GET • WHAT WITH A PARTNER AND ANSWER… IS AN ELEMENT?

MOLECULES • MOLECULES HAPPEN WHEN DIFFERENT ATOMS ARE GROUPED TOGETHER • WATER • H 2 O… • TWO HYDROGEN ATOMS • ONE OXYGEN ATOM

COMPOUNDS • COMPOUNDS ARE COMBINING OR • HUMANS ARE MADE UP OF MANY DIFFERENT COMPOUNDS/ELEMENTS • HUMANS ARE MADE UP OF 6 BASIC ELEMENTS… PUTTING TOGETHER MANY DIFFERENT MOLECULES/ELEMENTS TOGETHER • • • CARBON HYDROGEN OXYGEN PHOSPHORUS SULFUR NITROGEN

EOG QUESTIONS • WHAT IS COMPOSED OF MATTER? • WHAT IS TRUE ABOUT THE ATOMS & ELEMENTS OF TWO MAGNETS WHEN COMPARED TO EACH OTHER?
