The Element Cerium is defined as…

• A lustrous

• Iron-gray

• Malleable metallic rare-earth element that occurs chiefly in the mineral monazite.

• Exists in four allotropic

states, is a constituent of lighter flint alloys.

Physical Characteristics:•Soft• Silvery •Malleable• Ductile metalPraseodymium

metal reacts with all the halogens.

Naturally occurring

Slightly radioactive metal

It is estimated to be about three to four times more abundant than uranium in the Earth's crust•Thorium was successfully used as a breeding (fertile) source for nuclear fuel – uranium

•When used in molten-salt reactors, thorium bred to 233U removes weaponization dangers.

is a synthetic chemical element

A radioactive metallic of the actinide series, curium is produced by bombarding plutonium with alpha particles.

Curium is named after Marie and Pierre Curie, who discovered radium and polonium, but not curium. It has some specialized applications in research, but is not generally available outside a few institutions.

Californium is one of the highest atomic mass elements to have been produced in weighable amounts.

The element was first produced in 1950 by bombarding curium with alpha particles

•Detects explosives •Treatments for cancer

Plutonium

Used in oil refining industries because it speeds up the conversion of crude petroleum to make gasoline.

Ceramics - used to make colored ceramic and glasses .

Used in cameras and binoculars.

Used in glass and television to reduce glare.

Group of 15 elements that are very similar because their outermost orbital are empty.

Absorbed by bone

marrow and highly

poisonous.

Used in nuclear weapons and as a fuel in nuclear reactors.

If handled correctly plutonium is environmental friendly (used by NASA to power equipment on the moon).

Most use of plutonium was

during WWll the

“Atomic Bomb”

Metallic Chemical element

Silvery color and extremely bright

Rarely appears in pure form because of the reactivity to air

Try to not inhale because dust from the metal to the mouth,

nose, eyes, and lungs can irritate mucus membranes.

Neodymium Iron

Unstable chemical

Grouped together because of their chemical similarities

They are all bivalentthe properties differing only slightly

with different atomic numbers

Power source in heart pacemaker,

Treatment of cancer, and

Smoke detectors

Tends to be expensive since it is hard to extract reliably

Worlds most major producer is China

Slightly toxic

Soft silvery metal
