This lightest metal floats on water, skittering around releasing hydrogen.

This metal is strong and lightweight, but expensive and toxic.

Found in the common mineral borax, it is rarely seen in pure form.

This colorless gas makes up 78% of the atmosphere, and condenses to a liquid at -196 ^oC.

This colorless gas makes up 21% of the atmosphere, and liquifies at -183 ^oC.

This pale yellow gas reacts violently with virtually everything, including glass.

This inert gas gives off a characteristic bright red when ionized by a high current.

This soft silvery metal turns white in seconds, when exposed to air.

This metal burns with a brilliant-white light, making it a useful ingredient in flares.

It's the most abundant metal in the Earth's crust, and found in over 270 different minerals.

It is grown into large single crystals, cut into wafers, then used to create computer chips.

This metal occurs in red, white and black forms.  The red allotrope is found in matches.

One of the few elements found pure in nature, it's also called brimstone.

A pale yellow-green gas, it's used as a disinfectant for drinking water and in swimming pools.

A noble gas, it's inert and colorless until an electric current excites it to a sky-blue glow.

This metal is very reactive with water, generating heat and igniting the produced hydrogen.

Essential for living organisms, compounds of this metal are found in teeth and bones.

This lustrous metal can be combined with other metals to produce strong, lightweight alloys.

This metal resists corrosion, and can be added to steel to make stainless steel.

This silvery-gray metal resembles iron and is a required trace mineral for living organisms. 

By mass, the most common element on Earth, it has been used since ancient times.

Used in pigments, and in high-strength, high-temperature steel alloys.

This silvery-white metal is mined in Sudbury, Ontario and used in coins.

Incredibly useful in industry for wiring, heat sinks, coins and in brass and bronze alloys.

Commonly used in galvanization, coating iron or steel to protect against corrosion.

With compounds used in electronics, this metal will melt in your hand, liquifying at 30^o C.

Used in light emitting diodes and semiconductors, just like silicon above it.

Highly toxic, this metalloid was the poison of choice until detection became easy.

Liquid at room temperature, it evaporates rapidly into a choking purple-brown gas.

More abundant than gold, this precious metal had been used in coins since antiquity.

Used in battery production and pigments, its use is decreasing due to toxicity.

This low toxicity metal is used in many alloys, such as bronze and pewter.

A lustrous gray metalloid, its alloys are used in solders, bullets and plain bearings.

This inert gas, when excited by a high voltage discharge, glows a pale violet colour.

This silvery-gold alkali metal melts at 28 ^oC and is extremely reactive and pyrophoric.

This blue-gray metal is used in capacitors in high-tech electronic devices.

With the highest melting point of all the elements, this metal is used in light bulb filaments.

An expensive metal, so resistant to corrosion and oxidation that it's considered a noble metal.

A highly valued precious metal for coinage and jewelry since the beginning of recorded history.

Used in thermometers, it's the only metal element that's liquid at room temperature.

Soft, malleable and heavy it has the highest atomic number of all the stable elements.

Used in cosmetics and pharmaceuticals, it can form big beautiful crystals when pure.

This odorless, colorless gas, produced from elements in granite, is radioactive.

Widely used in self-luminous clock and watch hands, until discovered to be radioactive.

This silvery-white metal is used as a fuel in nuclear reactors, generating electric power.

This radioactive metal can provide power to spacecraft and artificial heart pacemakers.

This element is found as opaque black graphite as well as transparent diamond.

This inert gas glows a pale mauve color when excited with a high voltage electric current.

Used as a disinfectant, its crystals sublimate into a violet vapor when heated.

Compounds of this soft silvery metal are added to fireworks to impart a green color.

This colorless gas makes up 75% of the visible universe.
