Lesson 1C Flashcards
Contains protons and neutrons
Nucleus
shows a particular area in which an electron is likely to be
Electron Cloud Model
Have one or more electron subshells or sublevels
Electron Shell Model
force of attraction that holds together ions that opposite charge
Ionic Bonds
What is Cation and Anion?
Cation- positive charge
Anion- negative charge
ionic compounds that breaks apart the positive and negative ions
Electrolyte
two or more atoms share electrons rather than gaining or losing them by sharing one or two or three pairs of valence electrons.
Covalent Bonds
occur when new bonds form and old bonds break between atoms
Chemical Reactions
2 principal forms of energy
Potential and Kinetic Energy
collision energy needed to break the chemical bonds of the reactants
Activation energy
How does the concentration affect the activation energy?
with an increase of concentration, the no. of molecules with the minimum required energy will increase, and the rate of reaction will increase
How does the temp. affect the activation of energy?
as the temp. increases, molecules moves faster and collide more
A substance that speed up a chemical reaction by lowering the activation energy
Catalyst
Types of Chemical Reactions
-Synthesis Reaction
-Decomposition Reaction
-Exchange Reaction
-Reversible Reaction
-Oxidation-Reduction Reactions
What is monomers and polymer?
a monomer is a molecule with low molecular weight that can be combine with others of the same kind to form a chemical compound called as polymer
