What does nature like to do with avaleable energy?
Nature typically tries to reduce energy
What makes an atom unstable?
Atoms are unstable if they aren’t combined from incomplete octects. However, they become stabalized once put into octects.
What are the three main types of bonds?
Ionic, covalent, metallic
Ionic Bonds
transfer of electrons to achieve octect
Covalent Bonds
sharing of electrons pairs, has a part time octect
Metal
gives up electrons; becomes cation
non-metal
gains electrons; becomes anion
What do opposite ions do to each other?
Opposite ions pull each other and from crystal lattice.
How does nuclei affect the formation of covalent bonds?
The two nuclei attract the valence level electron another atom is trying to take from it
Melting point of covalent
Low (sucrose)
Melting point of ionic
High (NaCl)
Boiling Point covalent
Low (H2O)
Boiling point ionic
High (NaCl)
Conduction covalent
nothing
Conduction ionic
When in solutions and melted
State of matter covalent
Gas, liquid, or solids
State of matter ionic
Solids (NaCl)
How are the physical properties of metals formed?
The physical properties are formed from the loosely held electrons
How are the physical properties of pure metals and alloys explained?
Explained by the amount of electrons and positive nuclei
What do mettalic bonding and alloys conduct?
They conduct heat and electricity
Do metallic bonding and alloys have high melting/boiling points?
Yes
What are three words to describe metallic bonding/alloys?
Malleable, ductile, and metallic luster
