C2 Ion Struct

Edexcel C2 Ions, Ionic Structure and properties

QuestionAnswer
What is an ion? An atom that has lost or gained electrons
What is the SIGN of the charge for all metallic IONS? Positive
Do metallic atoms lose or gain electrons when they become ions? Lose
An element is in Group 1. What is the charge of the ion (sign and number)? +1
An element is in Group 6. What is the charge of the ion (sign and number)? -2
Sodium Ion is Na+ and Oxide ion is O-2. What is the formula of Sodium Oxide? Na2O (the 2 is in subscript) remember: all numbers are in subscripts/written at bottom; there are no +/- showing after the swap!
Magnesium Ion is Mg+2 and Oxide ion is O-2. What is the formula of Magnesium Oxide? MgO (it is the simplest ratio) remember: all numbers are in subscripts/written at bottom; there are no +/- showing after the swap!
Magnesium Ion is Mg+2 and Chloride ion is Cl-1. What is the formula of Magnesium Chloride? MgCl2 (the 2 is in subscript) remember: all numbers are in subscripts/written at bottom; there are no +/- showing after the swap!
Describe how particles are arranged in an ionic structure Ions are arranged in 3dimension; positive ions are surrounded by negative ions (and vice versa); the ions create a lattice
Describe THREE properties of ionic compounds Conduct electricity when liquid; high meting point and dissolve in water
Explain why ionic compounds are able to conduct electricity when liquid but not as a solid CHARGED particles (here ions) are able to MOVE in a liquid; but in a solid the charged particles can NOT move
Explain why ionic compounds have a high melting point There are STRONG electrostatic FORCES between the ions that require a lot of ENERGY to break
How do you know that CaCl2 is an ionic compound? Ca is a metal (group2) and Cl is a non-metal(group7)
Nitrate is (NO3)-1. What is the formula of Magnesium Nitrate? Mg(NO3)2 remember: all numbers are in subscripts/written at bottom; there are no +/- showing after the swap!
Carbonate is (CO3)-2. What is the formula of Sodium Carbonate? Na2(CO3) remember: all numbers are in subscripts/written at bottom; there are no +/- showing after the swap!
Sodium Nitrite is Na(NO2). What is the formula of the Nitrite ion? (NO2)-1 "rub off" the Sodium from the formula and you have the Nitrite: so (NO2) Now "unswap" the number that was after Sodium: here it was 1: so (NO2) 1 [1 as superscript) Finally, Sodium is a metal, so +ion, therefore the Nitrite is -: (NO2)-1
Sodium Sulfite is Na(SO3). What is the formula of the Sulfite ion? (SO3)-2 "rub off" the Sodium from the formula and you have the Sulfite: so (SO3) Now "unswap" the number that was after Sodium: here it was 2: so (SO3)2 [2 as superscript) Finally, Sodium is a metal, so +ion, therefore the Nitrite is -: (SO3)-2
What is the sign (charge) on all NON-metallic elements IONS? negative
Explain how a Calcium atom becomes a Calcium ion Calcium is in group 2; so all atoms have 2 e- in the outer shell; when the atom becomes an ion, it loses the 2 e- to become Ca+2
Explain how an Oxygen atom becomes an Oxide ion Oxygen is in group 6; so all atoms have 6 e- in the outer shell; when the atom becomes an ion, it gains 2 more e- to become O-2
Name the type of bonding in Sodium Chloride Ionic (because it is a metal combined with a non-metal)
CHALLENGE: Describe what happen to Sodium atom and Oxygen ATOMS when they make IONIC Sodium Oxide Who loses/gains e-? How many? What is the charge (and number) on the ions? Formula of compound?; Na atoms LOSE ONE e- to become Na+; O atoms GAIN TWO e- to become O-2; the formula is Na2O
CHALLENGE: Describe what happen to Sodium atom and Chloride ATOMS when they make IONIC Sodium Chloride Who loses/gains e-? How many? What is the charge (and number) on the ions? Formula of compound?; Na atoms LOSE ONE e- to become Na+; Cl atoms GAIN ONE e- to become Cl-; the formula is NaCl
