HEAVY, BLUISH-WHITE METAL, VERY SOFT, MELTING POINT 302 degrees C, BOILING POINT 1457 degreesC
LIGHT WEIGHT, HIGHLY CORROSION RESISTANT, EXCELLENT HEAT & ELECTRICITY CONDUCTOR, LOW MELTING POINT & DENSITY
VERY LOW MELTING POINT 29.7 degrees C, CAN BE SUPER COOLED EASILY, BOILING POINT 2,400 degrees C, DENSITY IS 5.9037 g, FAIRLY REACTIVE
CHARATERISTICS *HAVE 3 VALENCE ELETRONS *ARE METALLIC (EXCEPT BORON) *ARE SOFT & LOW MELTING POINT(EXCEPT BORON) *CHEMICALLY REACTIVE AT ROOM TEMP. (EXCEPT BORON) *DO NOT OCCUR ELEMENTALLY IN NATURE
*SELDOM DO THEY HAVE SIMILAR PHYSICAL PROPERTIES- MANY OF THOSE DEPEND ON THE ATOMIC MASS & RELATED PROPERTIES & THEY INCREASE DOWN THE GROUP *CHEMICALLY THEY ARE SIMILAR B/C THEIR VALENCE ELECTRONS STRUCTURES ARE THE SAME
BORON-HAS IMPORTANT APPLICATION IN TECH, INCLUDING:: NUCLEAR ENGINEERING & EXTREME ENVIRONMENTS B/C OF ITS LOW MASS, HIGH STRENGTH ,AND RESPONSE TO NUETRON RADIATION INDIUM-IS IN AUTOMOBILE BEARINGS TO IMPROVE MOISTURE RESISTANCE AND ANTISEIZURE PROPERTIES. ALSO IN THE SEMICONDUCTOR INDUST. B/C IT ACTS AS A DOPING AGENT IN THE FORMATION OF PTYPE GERMANIUM.
BORON FAMILY 3A
