Atomic Structure
Which experiment lead to the discovery of the nucleus?
Rutherford's alpha scattering experiment
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.
Name the three fundamental particles of an atom.
Proton, Neutron, Electron
Covalent bonds always form between nonmetals and ____________.
Nonmetals
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
Name the isotopes of hydrogen
Protium, Deuterium, Tritium
Which out of ionic and covalent compounds are conducting in nature?
Ionic
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.
How many unpaired electrons are there in a carbon atom in the ground state?
2
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
Which quantum numbers determines an electron’s spin direction?
Spin
What is the nature of bond formed between Sodium (group 1) and oxygen (group 16)?
Ionic
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
