Metallic Bonding and Stoichiometry Flashcards
(4 cards)
1
Q
What is metallic bonding?
A
Metals lose their valence electrons turning the metal atoms into positive ions. They form giant lattice structure of positive ions in the sea of electrons.
2
Q
How are the ratio of moles shown in this equation? 2Na(s) + O 2(g) → 2Na 2O(s)
A
The numbers at the start of compound and molecule.
2
Q
Formula for calculating moles?
A
n=m/M
n=v/24
n=c*v
3
Q
Formula of Percentage purity
A
mass of pure product/mass of the impure product * 100
