chemical bonding - Coggle Diagram
chemical bonding
physical properties of metals
lusterous
high density
good conducts of heat and electricity
ductile
malleable
sonorous
industries that use chemical bonds
food industry
pharmaceutical industry
clothing industry
air we breathe
steel industry
Giant covalent bond
2 charges on a molecule is a dipole
Diamond
solid form of element carbon
one carbon atom bonded to 4 carbon atoms
this structure makes diamonds hard
formed at high temp and pressure under earths surface
non soluble
Graphite
layered structure
one carbon is bonded to three carbons
forms layers
weak IMF between layers
strong covalent bonds
used in pencils and batteries
stable--> conducts electricity
3d structure of atoms that are joined by covalent bonds
covalent bonds
sharing of valence electrons
properties; low melting and boiling. points, not soluble, does not conduct electricity, flammable, soft and squishy
3 types of covalent bonds
single
made up of 2 shared electrons
double
made up of 4 shared electrons
triple
made up of 6 shared electrons
between 2 nonmetals
ionic bonds
an atom either loses or gains an electron to attain stability
properties; solid crystals at room temp, high melting and boiling point, brittle, conducts electricity and soluble
formed between a metal and nonmetal
intermolecular force
attractive force between neighbouring molecules
industries:
food
plants
medical
DNA
polar and nonpolar
polar
has a negative and positive charge
electrical dipole
interact with other polar substances
H2O, NH3,H2,S,C2,H6
polar covalent
share bonds unequally
charge will dissolve charge
like will dissolve like
Polar molecule
A polar molecule is a molecule with a difference in electrical charge between two ends
polar --> polar
nonpolar
no dipole
do not interact with polar substances
CO2, C6H6, CCI4,CH4
non polar covalent
shares electrons equally
nonpolar --> nonpolar
metallic bonds
electrostatic force between positively charged cations and sea of delocalised electrons
