20 Devices to show how the Internet of Things will be. Within eight years, it is expected that various organizations ranging from government to business will create a market of almost $9 trillion which will be constituted from 212 billion âthingsâ making up the global Internet of Things in 2020.
1 Allotropes are forms of the same element which exhibit different physical properties. 2  Elements such as carbon, oxygen, phosphorus, tin and sulfur, display allotropy.llotropes of Carbon. Both graphite and diamond are made up of carbon atoms, but the arrangement of atoms is different in each allotrope which results in different physical properties.
Group 13. Boron (B), the second hardest element, is the only allotropic element in Group 13. It is second only to carbon (C) in its ability to form element bonded networks. Thus, in addition to amorphous boron, several different allotropes of boron are known, of which three are well characterized.here are only three allotropic elements in Group 16, oxygen, sulfur, and selenium. Only two oxygen allotropes are knownâdinuclear oxygen (dioxygen, O 2) and trinuclear ozone (O 3) (Figure 6). Both are gases at room temperature and pressure.
