Calcium (Ca) - Chemical properties, Health and

Calcium . The chemical element Calcium (Ca), atomic nuer 20, is the fifth element and the third most abundant metal in the earth’s crust. The metal is trimorphic, harder than sodium, but softer than aluminium.A well as beryllium and aluminium, and unlike the alkaline metals, it doesn’t cause skin-burns. It is less chemically reactive than alkaline metals and than the other alkaline-earth

Astatine - Wikipedia

2019-4-14 · Astatine is a radioactive chemical element with syol At and atomic nuer 85. It is the rarest naturally occurring element in the Earth''s crust, occurring only as the decay product of various heavier elements. All of astatine''s isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. A sample of the pure

Local Spatial Autocorrelation Statistics: Distributional

The statistics G i (d) and G i *(d), introduced in Getis and Ord (1992) for the study of local pattern in spatial data, are extended and their properties further explored. In particular, nonbinary weights are allowed and the statistics are related to Moran''s autocorrelation statistic, I. The correlations between nearby values of the statistics are derived and verified by simulation.
