Calcium Crewneck Sweatshirts

An impeccable Calcium design. Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate. Brought to you by Periodic-Tees.com

Here's the periodic table element symbol for calcium, one of the alkaline earth metals.

Different elements burn with a different coloured flame – here’s some cute examples with some of their element’s characteristics. Strontium, Calcium, Sodium, Boron, Arsenic, Potassium. My son loves science, and has a great book on the periodic table of elements, it was kind of fun to research this one :)

Open this bad boy up and you'll receive a thirst only seen in essential minerals that have electrolytes. You know what they say, it's what plants crave and such a thirst mutilator.

The orbitals are swirling in Storistir to make holiday ornaments! Calcium, element 20, is a silvery metal that in its elemental form does not look like bone nor calx (Latin for chalk or limestone). The human body needs calcium to make and strengthen bones, circulate blood, release hormones and contract muscles. Vitamin D is needed to absorb calcium, and yes, both too much or too little calcium can have negative health effects.

Calcium phosphate crystal, coloured scanning electron micrograph (SEM). Crystalline materials have their atoms placed in regular lattices that can form geometric shapes like this. Calcium phosphate crystals contain both calcium (Ca) and phosphate (PO4) ions, but the precise ratio varies according to the crystal structure. Calcium phosphates are used in dental materials and also in foodstuffs. Magnification: x7100 when printed 10cm wide.

Parody of a certain range of personal hygiene products, this range of t-shirts highlights the atomic ingredients of the average human body. Figures are taken from wikipedia which gives an estimate of 7x10e27 atoms per human, and gives the percentage of atoms per element.

False-coloured Scanning Electron Micrograph of a cross-section through cancellous bone. Sometimes referred to as 'spongy bone' or 'trabecular bone', cancellous bone is found within the middle of large bones. The honeycomb like microstructure gives the bone strength whilst saving weight and provides an open structure that can be occupied by bone marrow. The individual struts are called 'trabeculae' a latin term meaning 'little beam'. This image is taken using a method that shows highly mineralised bone as brighter shades, lower mineralisation appears darker; such methods are useful when looking at calcium-poor bone, such as that from osteoporosis patients. Image width is 1.66mm.

Ocean inhabitants

Coccolithophore on needle tip. Coloured scanning electron micrograph (SEM) of a composition of the coccolithophore Emiliana huxleyi on a needle tip. This small algal organism is a calcareous phytoplankton and is surrounded by a skeleton (coccosphere) of calcium carbonate plates (coccoliths). When the organism dies, the plates separate and sink to the ocean floor. Coccolithophores are of particular interest to those studying global climate change because as ocean acidity increases, their coccoliths may become even more important as a carbon sink (absorb carbon dioxide). Individual plates have been found in vast numbers and can make up the major component of a particular rock, such as the chalk of England. E. huxleyi an important part of t...
