Chemistry: Intramolecular Bonding

i hate chem

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
