- valence Now, answer this question: Answer the following question given this paragraph: Electron Configurations and the Periodic Table As described earlier, the periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table (Figure 6.30), we also see a periodic recurrence of similar electron configurations in the outer shells of these elements. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom and are most easily lost or shared than the core electrons. Valence electrons are also the determining factor in some physical properties of the elements. Elements in any one group (or column) have the same number of valence electrons; the alkali metals lithium and sodium each have only one valence electron, the alkaline earth metals beryllium and magnesium each have two, and the halogens fluorine and chlorine each have seven valence electrons. The similarity in chemical properties among. Q: Which type of electrons plays the most important role in chemical reactions? A:
A:
output: valence

OPTIONS:
- chloride solutions
- sulfate solutions

Answer the following question given this paragraph: Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons. Therefore, the atomic number of an atom also tells you how many electrons the atom has. This, in turn, determines many of the atom's properties. Q: What are atoms called when they have the same number of negative electrons as positive protons in an electrical charge? A:
OPTIONS:
- positive
- static
- negative
- neutral

Answer:
neutral
