User: Magnesium has 2 valence electrons, and oxygen has 6 valence electrons. Which type of bonding is likely to occur between a magnesium atom and an oxygen atom? Select one of the options below as your answer: A. Ionic—Magnesium will give 2 electrons to oxygen, and both will become ions. B. Ionic—Oxygen will give 2 electrons to magnesium, and both will become ions. C. Metallic—Oxygen and magnesium atoms will be surrounded by a pool of electrons.

Weegy: In bonding with another element, magnesium has an oxidation number of +2. It gives away 2 electrons when it bonds. It will most easily bond with an element that accepts 2 electrons. [ With an oxidation number of -2 that is oxygen, which contains 6 electrons in its valence shell. The correct answer is C. ]

User: Suppose that you want to test the effects of different dishwashing detergents on dishes that have food stuck to them. To test the differences, you wash three loads of the same dishes, each with a different type of detergent, all in warm water. You also wash a fourth load of dishes with only warm water. The independent variable in this experiment is the type of detergent used. Select one of the options below as your answer: A. true B. false

Weegy: The control is washing the dishes in warm water only. It is the only thing that does not change throughout the experiment. hence the statement 'The independent variable in this experiment is the type of detergent used' is false
