Parts Of An Atom/The Periodic Table
Where is the nuclease at in an atom
Center
What is a chemical bond
attraction between atoms or ions that enables the formation of molecules
What is a chemical reaction
A process in which one or more substances, the reactants, are converted to one or more different substances, the products.
What is Chemical quantities
a systematic method to express quantities of the given chemical substance into scientific units.
What Is Chemical equilibrium
reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
How many parts are in a working atom
3
Are ionic bonds stronger then covalent bonds
No ionic bonds are not stronger the ionic bonds
What is reaction rate?
the speed at which a chemical reaction proceeds
the mass of one mole of any pure substance measured in grams
How is chemical equilibrium achieved
the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant
Where can you find the atomic mass of a element on the periodic table

What is the difference between Ionic and covalent bonds
Ionic bonds are held together by weak ionic bonds that are usually able to dissolve in water, and covalent bonds are strong generally not being insoluble.
Is wood burning a chemical reaction
Yes
How much is a mole
What is Le Châtelier's Principle
If an external stress is applied to a system at equilibrium, the system adjusts in such a way that the stress is partially offset as the system reaches a new equilibrium position.
What is the most common element on the periodic table
Hydrogen
Is covalent bonding sharing electrons between multiple atoms or when multiple ions are held together to make a bond with different charges
Sharing electrons between multiple atoms
what can be used to increase the rate of a chemical reaction
increasing concentration, increasing surface are, and increasing the tempature
Is molar mass and atomic mass equal
Yes
How many Elements are currently on the periodic table
118
How does increased temperature and concentration increase the reaction rate
The greater the concentration and temperature of the reactants, the more collisions there are and therefore, the reaction rate will increase
