Each carbon atom can bond with as many as _________ other atoms.
All ions have at least one ________ select all that are correct. a. proton c. electron b. neutron d. all of the above
Polonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o 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 why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of P210o change into after it emits an alpha particle.
Which of the following is a molecule, but not a compound? a. H2O b. 2H c. H2 d. H+
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. They can be stopped by, for example, a sheet of paper or a few inches of air. This property is one reason why 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 decay into after it emits an alpha particle?

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. What is the meaning of a mass number shown in parentheses?
