group 11 chemical
- Roentggenium belongs based on its theroetcial config. but it is a short lived transactinide with a half life of 26 secs.
- copper is toxic in excessive amounts
group 11 physical
- elements have low resistivity
- copper is the cheapest and most widley used
- copper
- silver
group 12 chemical
- high volaitilty
- poor conductors of heat but a fair conductor of electricity
group 12 physical
- lowest melting point of all transititon metals
- soft diamagnetic divalent metal
- zinc
- cadmium
group 13 chemical
- atomic radius increases down the group
- electrode potential increases down the group
group 13 physical
- aluminum is the most important metal in this family
- when bety.liu, and aluminum react with water the become slightly acitic
- boron
- aluminum
group 14 chemical
- each of the elelments have 4 electrons in its outer orbital
- the last orbital of all these elements is the p^2, orbital

- carbons crystal srutcure is hexagonal
- carbon
- silicon

group 15 chemical
- all elements are MH3 type hydrate
- density also increases on moving down the group with increase in atomic number
group 15 physical

- metalic character varies depending on atoimc mass
- nitrogen
- phosphourus
group 16 chemical
- shows high electronegativity
- have large negative electron gain epthalpy
group 16 physical
