Copper- second smallest, 4th period, atomic # 29
Calcium- second largest, 4th period, atomic # 20
Potassium- largest, 4th period, atomic # 19
Johann Dobereiner - noticed that the atomic weight of strontium fell midway between the weights of calcium and barium, elements possessing similar chemical properties. In 1829, after discovering the halogen triad (composed of chlorine, bromine, and iodine) and the alkali metal triad of (lithium, sodium and potassium) ***he proposed that nature contained triads of elements the middle element had properties that were an average of the other two members when ordered by the atomic weight (the Law of Triads)
Ice has an ordered structure.
An ordered value bar graph is a value bar graph in which data values are arranged in increasing (or decreasing) order of length.
Because vitamin D and calcium build bone mass, and well, osteoporosis means porous bones. So, theoretically, D & calcium fill the holes a little :)

The elements are lined up in order of increasing atomic number (number of protons).
Element's atomic number decide its place in periodic table. They r arranged in increasing order.
The tendency of a polymer to crystallize decreases with increasing molecular weight because as the chains become longer it is more difficult for all regions along adjacent chains to align so as to produce the ordered atomic array.
Oxygen, hydrogen, phosphorous, carbon, calcium, and nitrogen, not necessarily in that order, although i am sure the first two are correctly ordered
By analogy with the spectrum of visible light from violet to red, with colours ordered in increasing wavelength, the electromagnetic spectrum is the collection of all types of electromagnetic radiation ordered by increasing wavelength. EM radiation that we can detect runs from ultra-long wavelength radio waves used to communicate with submarines, through long-wave, short-wave, VHF and UHF radio to microwaves, infra-red (heat radiation), visible light, UV, X-rays and gamma rays.
Blood and urine tests may be conducted to check for levels of aldosterone, potassium levels, or renin activity. A computed tomography scan (CT scan) may be ordered to detect tumors
