100
Change in colour, change in odour, formation of a gas and release or absorption of heat energy are all evidence of this
What is a mixture?
100
Dmitri Mendelev created the first one
What is the periodic table?
100
These people discovered mercury, procedures for making mineral acid, improved lab equipment and strived to turn anything into gold.
What are alchemists?
100
Usually the first letter or first two letters of the element name or the latin name
What is the element symbol?
100
One thing you never do in a lab
What is (answer may vary) eating? Drinking? Horsing around? etc
200
Contains one kind of particle. Sometimes you can see the different particles sometimes you cannot
What is a chemical property?
200
Metals are on this side of the staircase
What is the left side of the periodic table?
200
Created the theory that all matter is made of small invisible particles, all atoms of the same element have identical properties, different elements have different properties, and atoms, in specific ratios, of different elements can create compounds
Who is John Dalton?
200
Represent the number of atoms of each element in one compound.
What are the numbers beside the element symbols?
200
Solid, liquid, gas
What are the three states of matter?
300
It is another name for a mechanical mixture
What is a heterogeneous mixture?
300
The first group of metals is called this
What are the alkali metals?
300
He discovered the electron using beams of particles and a vacuum. Created the raisin bun model.
Who is J.J Thompson?
300
Completely transfer one electron to another element in the compound. Contains one anion and one cation.
What is an ionic bond?
300
periods and groups respectively
What are the rows and columns in the periodic table?
400
One type of mechanical mixture the components are in different states and can be separated through filtration, in the other these cannot be separated.
What is the difference between a suspension and a colloid?
400
These elements have properties of both metals and non-metals
What are metalloids?
400
Modified the raisin bun model by proving that all the positive protons were located in the nucleus. Used gold foil and positive protons to prove this.
Who is Ernest Rutherford?
400
Contains only cations (which are....) and prefixes must be used to name this.
What is a molecular bond?
400
Lead (II) nitride and N2O4 respectively (Hint: chemical formula and name)
What is Pb3N2 and Dinitrogen tetraoxide.
500
A substance melts at a specific temperature, boils at a specific temperature and has a consistent solubility
What is a pure substance
500
atoms bond in such a way as to have eight electrons in their valence energy level. (atoms always try to have 8 electrons in their valence energy level)
What is the octet rule?
500
Proposed that electron orbited the nucleus in specific energy levels. Depending on the energy level filled the atoms emitted a different colour light.
Who is Neils Bohr?
500
determines how many bonding places an element atom has.
What is the charge or the number of valence electrons?
500
same as the atomic number, The atomic mass minus the atomic number and the outer level of these can be found using the group number.
What are the subatomic particles, protons, neutrons and electrons?
