- Magnesium has an atomic number of 12. Which of the following statements is true of a neutral magnesium atom? a. It has 12 protons, 12 electrons, and 12 neutrons. b. It has 12 protons, 12 electrons, and six neutrons. c. It has six protons, six electrons, and no neutrons. d. It has six protons, six electrons, and six neutrons.Which element has only one proton?Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?

- The pH of black coffee is 5, and that of milk of magnesia is 10. Is the coffee twice as acidic as milk of magnesia?Visit this website (http://openstaxcollege.org/l/ptable) to view the periodic table. In the periodic table of the elements, elements in a single column have the same number of electrons that can participate in a chemical reaction. These electrons are known as valence electrons. For example, the elements in the first column all have a single valence electron—an electron that can be donated in a chemical reaction with another atom.
