Chemistry
What charge is a neutron
A neutron hasno change at all
What does the term group mean when looking at the periodic table?
The columns on the table, or the up and down row
Exothermic reaction process
The energy of the reactants is high and heat energy is released
Define non renewable energy
A resource that does not renew itself at a sufficient rate
Definition of energy
The ability to cause change
Parts within an atom?
Protons, neutrons, electrons
What is a period when looking the periodic table?
Also called a row. Goes side to side
Endothermic reaction process
The energy of the reactents is low, energy is absorbed
Examples of non renewable energy
Fossil feuls, coal
What is the first law of thermodynamics
Energy cannot be created or destroyed only transferred
What are valence electrons?
The outer shell of electrons
What are some Metalloid characteristcs ?
Can be both shiny or dull, are solid
Define the law if conservation of mass
The amount of energy in the reactents is equal to the amount of energy in the products
Define renewable energy
A resource that can renew itself at a sufficient rate
potential energy example
A bird sitting on a tree
What are energy levels?
The circles around the nucleus, they have ale trans on them
Nonmetal characteristics
Dull, brittle, gain electrons
Products
What you get after a chemical reaction
List examples of renewable energy
Solar energy and wind energy
chemical energy examples
The coffee you drink in the morning
What is an ion?
An atom with a net charge due the the adding or subtracting of an electron
Nobel gas characteristics
Low reactivity or (happy) element, will not gain or lose electrons
Reactants
The thing that comes before a chamical reaction
What percent of the earths energy comes from the sun
99%
elastic potential energy example
A chip holder being opened or being closed
