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?

• Luster
• Good conductors of heat electricity
• Malleable ductile
• Low ionization energy low electronegativity
• 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?

• Hard, brittle
• High melting point, high boiling point
• Low vapor pressure
• Poor conductors of heat
• Solids do not conduct electricity at all
• Melts solutions do conduct a current
• 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.
