2) What’s special about this element?
Warm Up Dec. 8th, 2016 Atomic Number: 6 1) List # of electrons, protons, neutrons, shells, valence electrons, atomic mass, chemical symbol (and name if you know it); then draw a model of that atom and its Lewis Dot Structure. 2) What’s special about this element?

Physical Property Metals Non-metals Appearance Shiny Dull State at room temperature Solid (except mercury, which is a liquid) About half are solids, about half are gases, and one (bromine) is a liquid Density High (they feel heavy for their size) Low (they feel light for their size) Strength Strong Weak Malleable or brittle Malleable (they bend without breaking) Brittle (they break or shatter when hammered) Conduction of heat Good Poor (they are insulators) Conduction of electricity Poor (they are insulators, apart from graphite) Magnetic material Only iron, cobalt and nickel None Sound when hit They make a ringing sound (they are sonorous) They make a dull sound Physical* Property Metals* Non-metals* Appearance Shiny Dull State at room temperature Solid (except mercury, which is a liquid) Some are solids, more than half are gases, and one (bromine) is a liquid Density High (they feel heavy for their size) Low (they feel light for their size) Strength Strong Weak

Metals, Non-Metals, and Metalloids
Brain Pop Metals, Non-Metals, and Metalloids
5
Periodic Table #2 (Metals Etc)
Label as Metals, Nonmetals, and Metalloids; color each section differently and use a key.
6
Mixture* When two or more different substances are mixed, but not chemically combined.
7
How would you separate the following?
8
How would you separate the
following?
9
How would you separate the following?
10
Solution* A mixture where one part of the solution (solute) is dissolved into the other part of the solution (solvent).
11
Homogeneous* – A mixture in which the components are uniformly distributed.
Heterogeneous* – A mixture in which the components are not uniformly distributed.
12
So which is homogenous and
which is heterogeneous?
13
Then what is homogenous???
