What is the name of the compound with the chemical formula MgSe? Spelling counts.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct name of the compound with the chemical formula MgSe<\/strong> is:<\/p>\n\n\n\n

Magnesium selenide<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation<\/h3>\n\n\n\n

Magnesium selenide (MgSe) is an ionic compound<\/strong> composed of magnesium (Mg) and selenium (Se). To understand its name, it\u2019s important to examine both the elements involved and the rules for naming binary ionic compounds<\/strong>.<\/p>\n\n\n\n

1. Magnesium (Mg):<\/strong><\/h4>\n\n\n\n

Magnesium is a metal from Group 2 of the periodic table, meaning it is an alkaline earth metal<\/strong>. These elements typically form ions with a +2 charge<\/strong> (Mg\u00b2\u207a). In compound formation, magnesium readily loses two electrons to achieve a stable noble gas configuration.<\/p>\n\n\n\n

2. Selenium (Se):<\/strong><\/h4>\n\n\n\n

Selenium is a nonmetal from Group 16 (also known as the chalcogens). It typically forms an ion with a -2 charge<\/strong> (Se\u00b2\u207b) by gaining two electrons. This is because selenium wants to fill its outer electron shell to become stable.<\/p>\n\n\n\n

3. Ionic Compound Formation:<\/strong><\/h4>\n\n\n\n

To form a neutral ionic compound<\/strong>, the total positive and negative charges must balance. Magnesium contributes a +2 charge, and selenium contributes a -2 charge. Since the charges are equal and opposite, only one of each ion<\/strong> is needed to balance the compound, giving the formula MgSe<\/strong>.<\/p>\n\n\n\n

4. Naming Rules:<\/strong><\/h4>\n\n\n\n

For binary ionic compounds like MgSe:<\/p>\n\n\n\n

    \n
  • The name of the metal (cation)<\/strong> comes first and stays the same: magnesium<\/em>.<\/li>\n\n\n\n
  • The name of the nonmetal (anion)<\/strong> comes second, and its ending changes to -ide<\/strong>: selenide<\/em> (from selenium).<\/li>\n<\/ul>\n\n\n\n

    Thus, MgSe is named magnesium selenide<\/strong>.<\/p>\n\n\n\n

    Spelling is important because:<\/p>\n\n\n\n

      \n
    • \u201cSelenide\u201d (not \u201cselenite\u201d or \u201cselenate\u201d) specifically indicates a -2 anion.<\/li>\n\n\n\n
    • The suffix \u201c-ide\u201d is used only for binary compounds (two elements only).<\/li>\n<\/ul>\n\n\n\n

      Therefore, the correct and complete name is magnesium selenide<\/strong><\/p>\n\n\n\n
