ChemDesc:
ammonium hydroxide - concentration varies


Detail:
Actinium is a radioactive element that has a silvery white color. It's extremely radioactive and gives off a blueish glow in the dark.


Detail:
Melts at above 850 øC.Americium is a radioactive element that has a silvery white color that sullies 
in air. It has been used in fluid-density gauges, aircraft fuel gauges, and 
distance sensing devices.


Detail:
Boils at 1380 øC, melts at 630.5 øC
.Antimony exists in many allotropic forms such as a bright silvery white metal 
which is hard and brittle.Combined with either tin, lead, or copper it forms 
antifriction alloys that are used in machinery bearings.


Detail:
Boils at -185.7 øC, melts at -189.2 øC.Obtained from the fractional distillation of liquid air. Argon is used with nitrogen in filling electric light bulbs. Argon with helium is used as an inert atmosphere in scientific work.


Detail:
Melts at 814 øC. Arsenic is found in both the yellow and gray crystalline forms. Gray arsenic
is very brittle and tarnishes in the air. It sublimes under high heat. Because arsenic is highly toxic, it makes a good weed killer and insecticide.


Detail:
Astatine is a radioactive element that was sythetically produced.


Detail:
Boils at 1640 øC, melts at 725 øC.It has a silvery-white lustre when cut. Like many other light elements, it is very reactive. It displaces hydrogen in water to form barium hydroxide.
