Calcium, alone among the elements listed, does not form a diatomic molecule with another atom of itself.
The balanced chemical equation for the reaction between bromine gas (Br2) and calcium iodide (CaI2) is 3Br2 + 2CaI2 → 2CaBr2 + 4I2. The reaction results in the formation of calcium bromide (CaBr2) and elemental iodine (I2).
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
When liquid bromine is added to calcium iodide, the reaction results in the formation of calcium bromide and iodine. Calcium bromide is a salt composed of calcium cations (Ca2+) and bromide anions (Br-), while iodine is a diatomic molecule composed of two iodine atoms (I2). This reaction is a double displacement reaction where the bromine displaces the iodine in calcium iodide to form the two new products.
they are all in the same period in the periodic table, they all have the same valance number
Copper, calcium, and bromine are all chemical elements found on the periodic table. They each have unique properties and are essential for various chemical processes. Additionally, they all play important roles in biological systems - calcium is crucial for bone health, copper is a cofactor in many enzymes, and bromine is used in disinfectants and flame retardants.
Calcium is not diatomic. Oxygen, nitrogen, and bromine are diatomic elements, meaning they naturally exist as diatomic molecules (O2, N2, Br2), while calcium exists as individual atoms.
Calcium is the only element listed that is not diatomic. Nitrogen, oxygen, and bromine exist as diatomic molecules in their natural state (N2, O2, Br2), while calcium exists as a single atom.
Nitrogen is a nonmetal.
The balanced chemical equation for the reaction between bromine gas (Br2) and calcium iodide (CaI2) is 3Br2 + 2CaI2 → 2CaBr2 + 4I2. The reaction results in the formation of calcium bromide (CaBr2) and elemental iodine (I2).
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
Nitrogen has the highest electronegativity.
Nitrogen is the only one I know, but carbon can form a divalent ion with the formula C2H2-2, which occurs in calcium carbide.
Calcium bromide is composed of calcium and bromine atoms. The chemical formula for calcium bromide is CaBr2, indicating that each formula unit contains one calcium atom bonded to two bromine atoms.
When liquid bromine is added to calcium iodide, the reaction results in the formation of calcium bromide and iodine. Calcium bromide is a salt composed of calcium cations (Ca2+) and bromide anions (Br-), while iodine is a diatomic molecule composed of two iodine atoms (I2). This reaction is a double displacement reaction where the bromine displaces the iodine in calcium iodide to form the two new products.
Diatomic homonuclear molecules are hydrogen H2, oxygen O2, nitrogen N2, fluorine F2, chlorine Cl2, bromine Br2, iodine I2 and (theoretically) astatine At2. Diatomic heteronuclear molecules encompass a broader range of compounds such as carbon monoxide CO, hydrogen chloride HCl, lithium iodide LiI, cyanide CN and calcium oxide CaO.
CaBr is a compound (two or more elements bonded together), and apart from that it's name is calcium bromide. Except those two bonded would probably be CaBr2 , which would be called calcium dibromide
The period of bromine is the fourth period on the periodic table. It is in the same period as other elements such as potassium, calcium, and argon.
