WebThe dark blue and yellow spheres represent the magnesium and chloride ions, respectively. The ADP molecules are represented as sticks. (c) Representation of the … WebThe hydroxyapatite crystals in bone and teeth are imperfect due to ion substitutions, especially magnesium, chloride, carbonate, and fluoride. Carbonate (CO 3 2−) is the most important among them. Carbonate ions typically substitute for phosphate ions in the crystal, but can replace a hydroxide ion when present in higher concentration (>4% by ... talento brainly
Magnesium Chloride MgCl2 - PubChem
WebMagnesium chloride is an ionic compound that is made up of magnesium Mg 2 + and two chloride Cl - ions. The atomic number of magnesium is 12 so its electronic configuration is 1 s 2 2 s 2 2 p 6 3 s 2. The atomic number of chlorine is 17 so its electronic configuration is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 5. WebChloride, by definition, is an anion that has formed from an atom of chlorine. Since chlorine is in group 17, it will form a 1- anion. Because their charges are equal and opposite, there will be one \text { K}^+ K+ ion for every … WebMagnesium chloride solution, MgCl 2 (aq) – see CLEAPSS Hazcard HC059b.
