Text of Resources A 1 Flashcards pp.94-102

  • Resources A 1 Flashcardspp.94-102

  • Name properties of metals.

  • -shiny-reacts with HCl and CuCl2-conductive-malleable

  • Name properties of non-metals.

  • -Dull-Brittle-Non-reactive with HCl and CuCl2

  • Define:Malleable-Brittle-Ductile-

  • Malleable- Flexible or bendableBrittle- hard; breaks apartDuctile-can be drawn into wire.

  • Name five metals.

  • -Gold, silver, iron, zinc, copper, etc.

  • Name five non-metals.

  • - carbon, nitrogen, helium, chlorine, neon, etc.

  • What are metalloids and give examples of them.

  • -Substances that share properties of metals and non-metals.-B, Al, Si, Ge, etc.

  • What is a physical change and give two examples.

  • -where the original substance remains-melting, density, conductivity.

  • What is a chemical change and give two examples.

  • -where a new substance is created.-metal rusting, fuel burned.

  • Metals when purehave a high luster(are shiny).

  • Physical

  • Plants carry on photosynthesis in order to make food and oxygen.

  • Chemical

  • Metals are typically much better conductors of heat and electricity than are non mentals.

  • Physical

  • Bread dough increases in volume if it is allowed to rise before baking.

  • Chemical

  • A candle burns andbecomes smallerover time.

  • Chemical

  • Metals are typically ductile (can be drawn into wire).

  • Physical

  • Nitrogen gas, which isrelatively non reactive, canform nitrogen oxides at thehigh temperatures of anoperating automobileengine.

  • Chemical

  • Healing of a cuton your hand.

  • Chemical

  • Argon gas, rather than air, is used in many light bulbs to prevent oxidation (rusting) of the metal filaments.

  • Chemical

  • Tungstens high melting point makes it useful for light bulb filaments.

  • Physical

  • The hardness of diamonds enables them to be used on drill bits.

  • Physical

  • Mercurys high density and liquid state at room temperature make in useful in barometers.

  • Physical

  • Copper has a reddish brown color.

  • Physical

  • A puddle of rain water evaporates after a couple of days.

  • Physical

  • Sodium chloride, table salt, is dissolved in water.

  • Physical

  • Some metals become dull when exposed to air.

  • Chemical

  • Fish rotting

  • Chemical

  • Describe the nucleus

  • Center part of an atom that has protons and neutrons in it.

  • Describe energy levels.

  • They are the outer part of an atom where electrons are located.

  • What is the atomic number and mass for helium?

  • Atomic number is 2.Atomic mass is 4.0026.

  • Define atomic number.

  • Identifies each element and is equal to the number of protons.

  • Define atomic mass.

  • The weight of an atom found by adding the protons & neutrons.

  • Give the number of protons, electrons, and neutrons for Zn.

  • Protons = 30Electrons = 30Neutrons = 35

  • What are protons?

  • Positively charged particles in the nucleus.

  • What are neutrons?

  • Particles in the nucleus with zero charge.

  • What are electrons?

  • Negatively charged particles located in the energy levels.
