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
bendable
Brittle- hard; breaks apart
Ductile-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 pure
have 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 and
becomes smaller
over 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 cut
on your hand.
Chemical
Argon gas, rather than air, is used in many light bulbs to prevent oxidation (“rusting”) of the metal filaments.
Chemical
Tungsten’s high melting point makes it useful for light bulb filaments.
Physical
The hardness of diamonds enables them to be used on drill bits.
Physical
Mercury’s 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.
