Bonds
Formed between 2 metals
What is Metallic bonds
A reaction that feels hot
What is exothermic reactions
can be observed or measured without changing composition or matter
What is physical property
Not shiny, low melting point, do not conduct energy or heat, brittle and low density.
What is non-metals
Made By Nature
What is a Natural Polymer
electrons are not shared equally between atoms
What is polar covalent bonds
The result of the reaction feels cold
What is endothermic reactions
can bee measure or obsserved only when matterr undergoes a change to become an entirely different kind of matter.
What is chemical properties
brittle, and semi conductors
What is metalloids
Made in labs or Factories
What is Synthetic Polymers
2 atoms that share valence electrons
what is covalent bonds
the product is always water and carbon dioxide
What is combustion reactions
Effecting the form of a chemical substance but not its chemical composition. Used to separate mixtures into their component compounds. Ex. Condensation
What is physical changes
Soft, brittle, and dangerous
What is post transition metals
large molecules that are made out of many smaller molecues joined together by covalent bonds
What is a Polymer
formed between metals and non-metals
What is Ionic bonds
General Form: AB+CD--->AD+CB
What is double replacement reactions
Matter changes into an entirely different substance with different chemical properties. Chemical Reactions can not easily be undone.
What is chemical chhanges
Shiny, silvery white color, low density, low melting point, and low boiling point
What is Alkaline Earths
Ability to form bonds with polymers
What is Carbon
relatively weak bond that is attracted through partial positive and negative charges.
What is Hydrogen Bonds
General Form: A+ BC---> AC+B
What is single replacement reactions
A heterogenous with large particles.
what is Suspension
Odorless, flavorless
What is noble gasses
Smaller repeating molecules
What is Monomer
