Chemistry
The study of the composition of matter and the changes it undergoes.
This property depends on the type of matter in a sample, not the amount.
What is an Intensive Property?
This model has a positively charged nucleus in the center with rings representing orbitals drawn around it.
What is the Bohr Model?
This type of bond is formed by the electrostatic forces between negative and positive ions.
What are Ionic Bonds?
In biology an insectivore; in chemistry a measure of very small things
What is a Mole?
The study of all chemicals that in general do not contain carbon.
What is Inorganic Chemistry?
A precipitate forms in a solution. This can now be classified as a __________ mixture.
What is Heterogeneous?
The Aufbau principle, Pauli exclusion principle, and Hund's rule help determine how to write this.
What is Electron Configuration?
This is the lowest whole number ratio of the ions in an ionic compound.
What is a Formula Unit?
The structural formula for water is HOH; HOOH is the formula for this solution that you might keep in your bathroom or first aid kid
What is Hydrogen Peroxide?
This tool can be used if chemicals are accidentally splashed into the eyes during a lab procedure.
What is the Eye Wash Station?
This law states that in any physical or chemical change the mass of the reactants is conserved.
What is the Law of Conservation of Mass?
Dobereiner, Mosely, and Mendelev all worked to create this.
What is the Periodic Table?
This is the family name of the elements who have 7 valence electrons.
What is Halogens?
2 letters longer than activity, this is high in the halogen elements so they're not naturally found uncombined
What is Reactivity?
A man walks 10 minutes to the store, he spends 14 minutes shopping, and takes another 16 minutes to get home because he stopped and talked to a neighbor. How many seconds did the man travel?
What is 2,400 Seconds?
These subatomic particles were sent through a cathode ray tube by J.J Thompson in 1897.
What are Electrons?
The periodic table can be split into three categories based on their metallic properties.
What is a Metal, Nonmetal, and Metalloid?
This is a molecule consisting of only two atoms.
What is a Diatomic Molecule?
Just like mercury this element Br is a liquid at room temperature
What is Bromine?
These are the people who developed tools and techniques for working with chemicals before chemists existed.
Who are Alchemists?
This element in Period 3 has 16 neutrons.
What is Sulfur?
The elements in the f orbital are also referred to as this.
What are Inner Transition Metals
The electrons in a covalent bond that are not used for bonding are commonly referred to as this.
What are Unshared or Unpaired Electrons or Lone Pairs?
This type of bond is formed by 2 atoms each contributing 1 electron to a shared electron pair
What is a Covalent Bond?
