Atomic Rules The MASS of the atom comes from the number of protons plus neutrons. You determine the CHARGE of an atom by subtracting protons minus electrons or electrons minus protons. (Put the bigger number first when you subtract. If there are more PROTONS, the atom will be POSITIVE and if there are more ELECTRONS, the atom will be NEGATIVE.) To figure out the IDENTITY of an atom you need to count the number of protons and match this number to the atomic number in the Periodic Table.

#5 Seven Courses of Thanksgiving Science (11/16/18)

(pp. 302-303) QUESTION ANSWER #6: Arranging the Elements (11/26/18) What information did Mendeleev use to sort elements?   How did Mendeleev arrange the elements? What does it mean that the properties of elements are periodic? How did yesterday’s card activity model what Mendeleev did with the elements? 1) density, appearance, atomic mass, melting point, compounds formed 2) in order of increasing atomic mass 3) have a regular, repeating pattern 4) we sorted cards by certain characteristics like he sorted the elements; we were able to predict the “properties” of the missing card like he predicted the properties of undiscovered elements our days of the week

#7: Table Teaser 1 (11/27/18) What is it? Rearrange the symbols for the elements and use the clues provided to figure out the words. pp. 744-745 Th + Pa Example: Something to follow Thorium + Protactinium 1. You’ll want to be first! Cerium + Radium 2. Masked bandit Nitrogen + Cobalt + Radium + Oxygen 3. Not anybody Oxygen + Boron + Dysprosium + Nitrogen + Oxygen 4. Beware of this snake! Oxygen + Carbon + Boron + Radium PATH

#8: Table Teaser 2 + Sodium demo (11/28/18) What is it? Rearrange the symbols for the elements and use the clues provided to figure out the words. pp. 744-745 1. A holiday decoration Hydrogen + Tungsten + Rhenium + Astatine 2. Water vapor Americium + Sulfur + Tellurium 3. Not first Cobalt + Neodymium + Selenium 4. Lemons make you do this Erbium + Uranium + Potassium + Phosphorus + Carbon
