The elements of Group 2 are beryllium, magnesium, calcium, strontium, barium, and radioactive radium. Reaction of calcium with water. For the best answers, search on this site https://shorturl.im/awpBG. The reaction between strontium and nitrogen gas (which has the formula N2) produces strontium nitride, which has the formula Sr3N2. Reactions with Group 2 Elements. Part of NCSSM CORE collection: This video shows the reaction of Ca metal with oxygen. This page looks at the reactions of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium - with air or oxygen. The reaction forms calcium hydroxide, Ca(OH) 2 and hydrogen gas (H 2). Similarly to Group 1 oxides, most group 2 oxides and hydroxides are only slightly soluble in water and form basic, or alkaline solutions. Incompatibilities & Reactivities Water (liberates heat), fluorine, ethanol [Note: Reacts with water to form calcium hydroxide.] The Facts. Combination of Calcium to other chemical: Calcium + chlorine= CaCl2 Calcium + Phosphorus=Ca3P2 Calcium phosphide Calcium + Oxygen + Silicon=CaSiO3 They called as Calsium Silicate Bromine = Br2, with a charge of 1-, since it tends to gain one electron when it reacts (it is also a diatomic molecule, so it forms in pairs of atoms, hence the subscript 2). This is due to Calcium being oxidation state +2 and Oxygen oxidation state is -2, this means when formed in a compound they cancel each other out to give CaO. Calcium reacts slowly with water. The presence of a calcium ion in the inorganic active site of the complex that produces oxygen is particularly puzzling, because the reaction is a redox process involving the transfer of multiple electrons, whereas calcium is redox inactive (it cannot transfer electrons under biological conditions). The balanced equation is: 3Sr + N2 -> Sr3N2. Calcium (Ca) is a metal element located in group 2 of the periodic table, and oxygen (O) is a nonmetal element located in group 16. The usual reaction product from a reaction between calcium and oxygen has the formula CaO and therefore contains one atom of each element per molecule. Noncombustible Solid, but will support combustion by liberation of oxygen. Word Equation: Calcium + Bromine >>>> Calcium bromide When ignited, Calcium burns to give calcium xxide. The mechanism of oxygen production in photosynthesis remains unresolved, despite many studies. On the whole, the metals burn in oxygen to form a simple metal oxide. Reaction of Calcium with Oxygen Calcium metal slowly oxidizes in air, becoming encrusted with white \(CaO\) and \(CaCO_3\), which protect from attack by air. Formula and structure: Calcium oxide chemical formula is CaO and its molar mass in 56.0774 g mol-1.The molecule is formed by the calcium cation Ca +2 and the oxygen anion O-2, which form a ionic bond.The calcium oxide ionic lattice is cubic and similar to NaCl lattice, with an ion surrounded by 6 opposite charge-ion. Formation of simple oxides. Alkaline earth metals also react with oxygen, though not as rapidly as Group 1 metals; these reactions also require heating. It explains why it is difficult to observe many tidy patterns. The reactions with oxygen. Calcium = Ca, with a charge of 2+, since it tends to lose two electrons when it reacts.
