Do Now: You will need to complete SCOPES Day 1 I will be walking around checking for the 3C’s on your paper For each question, we will use the 3C’s method: Check for key words. Circle them Cross out the obviously incorrect answer choices Choose the best answer         Materials Needed from Backpack: Writing Utensil, Scissors, Glue, Diff. Colored Pens/Pencikls

1.4 Day 1 Anything that has mass and takes up space (i.e. has volume) How much space something occupies (usually measured in mL or cm3) A characteristic of matter learned by observation (look, shape, texture, etc.) Solid, liquid, gas (and also plasma)

Darken in the “stairstep”. This is where the metalloids are located.

Shade in the metalloids. The metalloids are located on either side of the “stairstep”. Aluminum touches the “stairstep” but is NOT considered a metalloid.

Shade in the metals. They are located on the right side of the table. Hydrogen is located on the right side but is NOT a metal.

Shade in the nonmetals. Nonmetals are located on the right side of the table. Do not forget to shade in Hydrogen, it is the only nonmetal located on the left side of the table.

Luster: how light reflects off surface (shiny) Ductile: can be pulled into a wire. Malleable: can be pressed into thin sheets. Good conductors of heat and electricity. Mostly SOLID at room temperature, with the exception of Mercury (Hg) Have physical properties of both metals and nonmetals. Found on the “stairstep”. Boron is at the top of the “stairstep”. Brittle: can break very easily. Poor conductors of heat and electricity. Mostly GAS at room temperature.

Boron: heat resistant alloys, rocket fuel igniter Silicon: glass, semi-conductors in electronic devices Arsenic: poison, wood preservation, insecticides Copper: electrical wires and motors Gold: jewelry, dental work, electronic devices Sodium: medicine, agriculture, salt Oxygen: supports life Chlorine: water purification, antiseptic Helium: balloons, cooling medium for large machines

18 GROUPS/FAMILIES PERIODS 7 Elements within the same period have the same number of energy levels or electron shells. They have the same number of valence electrons and have similar chemical properties. Groups 1 and 17 are highly reactive because they either want to give or receive 1 valence electron.
