When two atoms of this chemical element combine, then it forms a gas and this gas is known as oxygen gas. This is a smell less and color less gas, and very important for the life on our Earth.Answer and Explanation: We are given the following data: The given total atomic ...
The 17O chemical shifts of simple aliphatic ethers were studied, and the additivity substituent increments for carbon atoms in the alkyl groups were determined. The additivity parameters were used to establish a linear correlation with experimental data for a series of aliphatic ethers, alcohols,...

is given credit for the discovery of oxygen. Later work showed the new gas to be a constituent of nitre, a common name forpotassium nitrate(KNO3), and, accordingly, it was named nitrogen by the French chemist Jean-Antoine-Claude Chaptal in 1790. Nitrogen first was considered achemical elemen...
Argon atoms have been trapped mechanically in cagelike cavities among molecules of other substances, as in crystals of ice or the organic compound hydroquinone (called argon clathrates). Element Properties atomic number 18 atomic weight [39.792, 39.963] melting point −189.2 °C (−308.6 °F)...
We describe a series of isostructural porphyrin-based coordination polymers, each containing Au single atoms (COFX-Au, X = 1 through 5), which are applied to photocatalytic nitrogen fixation. Au single atoms, as well as light-harvesting antennae, are immobilized by the porphyrin building blocks...
