Title: Flashcards for Ionic


1
Flashcards for Ionic Metallic Bonding
2
What particle is transferred in ionic bonding?
  • Electron

3
How do you identify an ionic formula?
  • Metal Nonmetal

4
How do you identify a covalent formula?
  • All Nonmetals

5
What do metals do?
  • Metals lose electrons form positive ions.

6
What do nonmetals do?
  • Nonmetals gain electrons form negative ions.

7
What are the properties of metals?
  1. Luster
  2. Good conductors of heat electricity
  3. Malleable ductile
  4. Low ionization energy low electronegativity
  5. High mp, high bp low vapor pressure

8
Why do atoms form bonds?
  • To get the same electron configuration as the
    nearest noble gas.

9
What is a chemical bond?
  • Force of attraction that holds 2 atoms together.

10
What are the properties of ionic compounds?
  1. Hard, brittle
  2. High melting point, high boiling point
  3. Low vapor pressure
  4. Poor conductors of heat
  5. Solids do not conduct electricity at all
  6. Melts solutions do conduct a current
  7. Ions in solution react quickly

11
What is the structure of ionic compounds?
  • Crystal lattice lattice points are positive
    negative ions.

12
Empirical Formula
  • Subscripts in chemical formula have smallest
    whole number ratio

13
Empirical Formula
  • Ionic compounds only have empirical formulas.

14
Crystal lattice
  • Regular, repeating pattern in 3 dimensions.

15
Compounds are electrically
  • Neutral.

16
Molecular Formula
  • Gives exact composition of molecule.

17
What is the structure of metals.
  • Crystal lattice all lattice points are positive
    ions.

18
Delocalized electrons
  • Valence electrons in metals are free to roam
    throughout the metal.

19
Sea of mobile electrons
  • Phrase used to describe valence electrons in
    metallic bonding.

20
Subscripts in chemical formulas
  • Microscopic scale give atomic ratios
  • Macroscopic scale give mole ratios

21
Lewis Dot Structures for Ionic Compounds
  • Have square brackets and charges. Charges add
    up to 0. Positive ion has no dots. Negative ion
    has 8 dots.

22
Group 1 metals form
  • 1 ions

23
Group 2 metals form
  • 2 ions

24
Group 16 nonmetals form
  • -2 ions

25
Group 17 nonmetals form
  • -1 ions

26
Group 18 nonmetals form
  • They dont form ions. There the noble gases!

27
NaCl
  • Binary Ionic Cmpd.
  • Na has only 1 oxidation state.
  • Sodium Chloride

28
FeCl2
  • Binary Ionic Cmpd.
  • Fe has 2 possible oxidation states.
  • Iron (II) chloride

29
Names
  • Words Roman Numerals

30
Formulas
  • Symbols Subscripts

31
Fe(NO3)3
  • Contains a polyatomic.
  • Fe has 2 possible oxidation states.
  • Iron (III) Nitrate
