Sele

niu

m

Element Symbol-Se eˉ Configuration-[Ar]4s23d104p4

Element Classification-non-metal

State of matter-Solid Physical Properties-Melting Point: 217ºC

Boiling Point: 688ºC Chemical Properties-More light shined on

it, better conductor of electricity.

Used extensively in electronics such as

photocells, light meter, and light cells

Occurs naturally in nature through

natural processes and human activities

Humans exposure to selenium is mainly

through food, because it’s naturally

present in grains, meats, and in cereal.

Tellu

rium

Element Classification-Metalloid

State of Matter-Solid Chemical Properties-Unusual

property of combining with gold,

gold normally doesn’t combine

with many elements Physical Properties-Melting

Point:449.51ºC Boiling

Point:988ºC Tellurium was discovered by

Franz Joseph Müller Von

Reichenstein, a Romanian

mining offical Primary used as an alloying

agent Most often found in the ores

sylvanite, calaverite, and

krennerite

Polo

5d10 6p4 Element Classification-Metal

State of matter-Solid Chemical Properties-

Radioactive Physical Properties-Melting

Point:254ºC Boiling Point:962ºC

Named after Poland Used to eliminate static

electricity in machinery

Usually produced by

bombarding bismuth-209 with

neutrons in a nuclear reactor,

which forms bismuth-210 and

decays into polonium-210

through beta decay
