100
What are the three main parts of an atom AND their charges.
Protons (+) , Electrons (-) and Neutrons (o).
100
What is an electron configuration?
The arrangement of electrons surrounding an atom.
100
True or false? Ionic formation happens in factories where they build contraptions to flatten clothing using heat and steam.
False....no really.

Why is NaCl2 a compound? DOUBLE JEOPARDY!! Give two reasons
1. has more than one element. 2. chemically joined DOUBLE JEOPARDY!! get both...
200
Define Compound
You must say- 1. More than one element. 2. Chemically joined together. You could say that they can only be separated chemically.
200
Describe the parts of an atom with regard to their mass. DOUBLE JEOPARDY! - what is the unit used for mass of an atomic constituent?
Protons and Neutrons weigh the same - 1. An Electron's weight is so small it is disregarded. DOUBLE JEOPARDY!! amu 1 atomic mass unit = 1.66053886 × 10^-27 kilograms
200
What are the things called that hold the electrons in their pattern?
Orbital shells
200
Two atoms that have been chemically joined have formed an _______ ___________
Ionic Compound
200
The process of moving the numbers around in order to combine two ions is known by what catchy phrase?
Swap and drop
300
Define Mixture
You must say- 1. More than one element or compound 2. Physically joined together. You could say that they can be separated Physically.
300
Give the numbers of each part of the atom for Chlorine 37, 17.
Protons 17, Electrons 17, Neutrons 20.
300
How many electrons can be held in each layer before it is full?
2,8,8,2.
300
What term is used to describe an ion that has a full outer shell of electrons?
Stable.
300
Compounds often end in ATE or IDE. how do you know which one to use?
IDE - One or less Oxygens cos the rest are 'idden. ATE - More than One Oxygens like 'Eight (ate)' for example.
400
Split these into element, compound or mixture. Water, O2, Lead piping, a football, a balloon, Baking soda, S8, A water bottle (including the water). A copper kettle,
Compound, Element, Element, Mixture, Compound, Compound, Element, Mixture, Element.
400
Give the atomic arrangement for Mg 12, 24. Beryllium 9, 4. Hydrogen 1,1. Argon 40, 18. and Astatine 85, 210.
In order of PEN Mg 12, 12, 12. Be 4,4,5. H 1,1,0. Ar 18,18, 22. At 85,85 125.
400
Define 'valence electrons'
These are the electrons in the outermost 'layer' surrounding the atom.
400
If an Atom has a full outer shell it is also known as what?
Inert or Noble gas.
400
What is the formula for the ionic compound created by the combination of Fe3+ and HCO3- DOUBLE JEOPARDY!! Name it.
Fe(HCO3)3 DOUBLE JEOPARDY!! Iron Hydrogen Carbonate
500
Separate these into molecules and elements. Sulfur, Argon, Gold, Hydrogen, Phosphorous, Iodine.
S8, Ar, Au, H2, P4, I2.
500
Considering that you will get immediate disqualification if any member of your team even considers looking at the wall chart... List the first 20 elements..... in order.... with symbols.
H He Li Be B C N O F Ne Na Mg Al Si P S Cl Ar K Ca
500
Give the electron configuration of Calcium 20, 40. Explain how many valence electrons it has AND whether it is stable or not.
2,8,8,2. 2 Valence. No it is not. The outer layer can hold more than 2. So it loses 2 to become stable.
500
Define an Ion... In its entirety. (At least four parts to the definition)
1.An Ion is an atom that has gained or lost electrons. 2.After it has done this it is left with a full outer shell. 3.It does this to become stable. 4.After it does this it becomes electrically charged.
500
Give the ionic compound formed when Magnesium and Chlorine Ions join together. Explain your answer (you can't guess) AND name the compound.
Mg is the 12th atom. Config 2,8,2 looses 2 becomes Mg2+ Cl is the 17th atom. Config 2,8,7 gains 1, becomes Cl- Compound needs 1x Mg and 2x Cl so result is MgCl2 Magnesium Chloride
