QuestionAnswer
What is an Ion? Give examples.This is simply a charged particle. Cl- [Chloride] or NO3 [Ammonium Ions]
Why do Atoms become Ions.This is to full the Electron Outer Shell. This is a stable place from Atoms. They achieve this by Loosing an Electron, or gaining.
What happens when Metals and Non-Metals become Ions?Metals become Ions by Loosing an Electron, making a Positive Ion Non-Metals become Ions by Gaining an Electron, making a Negative Ion
What are the 4 Groups in the Periodic Table to most likely form IonsGroup 1-2 and Group 6-7.
Which Groups are the Metals, and the Non metals. What charge do they form?Group 1 is Metals, They make a +1 Charge. [They lose 1 electron] Group 2 is Metals, They make a +2 Charge [They lose 2 electrons] Group 6 is Non-Metals. They make a -2 Charge [They gain 2 Electrons] Group 7 is Non-Metals. They make a -1 Charge [They gain 1 electron.]
What do the Elements in G1-2 and G6-7 have in common?They all have a Full Outer Shell once reacted. This is usually 8
What is the Reactivity Series for G1-2 and G6-7G1-2 has it getting easier to Remove the Outer Electrons [Gets More Reactive as you go down the Group] G6-7 has it getting the Electron Harder for the Nucleus [Gets Less Reactive as you go down the Group]
Explain the Reactivity Series for G1-2 and G6-7G1-2 gets more Reactive because the Electron is further away from the Nucleus, the Atom is bigger and the Attraction of the Positive Nucleus and the Negative Electron is Weaker G6-7 gets Less reactive because the Positive Nucleus can spend More Energy to gain a Electron, because its Closer. As you go down, the Attraction gets weaker.
What happens when a Metal and a Non Metal reacts?So the Metal can Lose the Outer Electron/s making a Positive Ion, and that Lost Electron is given to the Non-Metal, which turns into a Negative Ion. These Ions are Oppositely Charged meaning that they can be Attracted together by strong Electrostatic Forces. This creates an Ionic Bond
What happens when 1. Sodium reacts with Chlorine 2. Magnesium with Chlorine1. Potassium is a G1 Element meaning its going to lose 1 electron [+1 Charge] Chlorine is a G7 Element meaning it wants 1 Electron [-1] Charges are balanced out meaning they can make NaCl [Sodium Chloride] 2. Magnesium is a G2 Element meaning its going to lose 2 Electron [+2] Chlorine is a G7 Element meaning it wants 1 Electron. The charges here are Not Balanced, but we make it by adding another Chlorine, making it want 2 Electron [-2] So now we can have Magnesium Chloride [MgCl2] [small 2]
So what does it mean when an Ionic Compound has a Giant Ionic Lattice Structure?This is simply the Ions making a Close Packed arrangement, that has Strong Electrostatics Forces keeping it in Place, in All Directions. This has no Gaps.
What are some of the Properties that an Ionic Compound hosts?-They have a High Melting Point, along with a High Boiling Point because of the Energy needed to break the Electrostatic Force of Attraction -They can't conduct Electricity, in a Solid State, as the Ions can not Move [From the Electrostatic Forces in the Lattice Structure] but when its in a Liquid State, the Ions Can Move, which can carry Electricity -They can also easily dissolve in Water, which splits up the Ions, and can also carry an Electric Charge
