1. Magnesium and nitrogen react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them.
Magnesium’s position in the periodic table (group 2) tells us that it is a metal. Metals form positive ions (cations). A magnesium atom must lose two electrons to have the...

An ion compound contains an unknown ion X and has the formula X3N2. Ion X contains 10 electrons write down the chemical symbol of X.
Solution:X3N2 → 3X2+ + 2N3-Number of electrons in X2+ ion = 10Therefore,Number of electrons in X = 10 + 2 = 12Number of electrons in X = Number of protons...

An element X forms both a dichloride (XCl2) and a tetrachloride (XCl4). Treatment of 10.00g XCl2 with excess chloride forms 12.55 XCl4. Calculate the atomic mass of X, and identify X.
Treatment of 10.00g XCl2 with excess chloride forms 12.55g XCl4. That means that the mass increases by 2.55g and it is the mass of 2 amounts of Cl. In XCl2...
