100
Created the original Atomic Theory and said atoms were solid particles.
Who is Dalton
100
A row across the periodic table.
What is a period
100
An atom that has lost electrons and become positive
What is CATION
100
Why compounds form in the first place.
What is to get a full outside shell and become more stable.
100
Reactions sometimes produce an insoluble solid from two clear liquids. We call this solid a ________ because it falls to the bottom.
What is precipitate
200
Discovered that atoms have some negative charge.
Who is Thomson.
200
The number of valence electrons for Be, C, and F
What is 2, 4 , and 7
200
The outside shell of electrons
What is Valence
200
When atoms lose or gain electrons, then attract because they have opposite charges. These compounds have high melting points with strong attractions.
What is Ionic compound,
200
DAILY DOUBLE: What three things can cause a double replacement reaction to occur?
What is gas, molecular (liquid), or insoluble solid formed.
300
Discovered that the atom is mostly empty space and did this using gold foil and positive particles
Who is Rutheford
300
DAILY DOUBLE: The family of elements that are non-metals and are the most reactive non-metals.
What is Halogens
300
An electron that has gone up a level by absorbing energy
What is excited
300
Charges are not needed for these compounds because they share electrons. We use prefixes to indicate how many of each are present.
What is Covalent
300
Balance the equation: Al2S3 + NaOH ----> Al(OH)3 + Na2S
What is 1,6,2,3
400
The shapes of the following orbitals in the quantum model. d, s, p, f
What is clover, sphere, peanut (figure 8) and undefined
400
When you go down a family, you have more levels of electrons that block the outside levels. This is called:
What is shielding
400
When measurements are "on target" - like measuring the boiling point to be 100 degrees C when it is supposed to be 100 degrees C.
What is accurate
400
DRAW + 100 extra points: 2,3 dimethyl 4 bromo hexane. What kind of compound is it?
What is organic
400
What kind of reaction is Cu + NaI and will it occur?
What is single replacement and no - cu is too low on reactivity chart.
500
The newest theory of the atom that suggests that protons and electrons and neutrons are made of smaller particles that are basically just energy.
What is String Theory
500
The man who produced the periodic table and what he used to arrange it:
Who is Mendeleev and he used the mass of the elements and their properties.
500
An atom of the same element that has the same protons, but a different mass or number of neutrons. ex: C-12 vs C-13
What is an Isotope
500
Name HBr, HClO2, and HNO3
What is hydrobromic acid, chlorous acid, and nitric acid.
500
When Oxygen combines with sodium, what kind of reaction is it and what would you SEE happen? Is it endo or exothermic?
What is combination, you would see light produced, and it is exothermic.
