Atom Review

Example Problem #1 Fluorine has an Atomic Number of 9. Draw an atom of fluorine. How and why will fluorine react?

Example Problem #1 Fluorine has an Atomic Number of 9. Draw an atom of fluorine. How and why will fluorine react? 9p + 9n Since atoms are stable with 8 electrons in their valence shell, fluorine will tend to bind with atoms that have one electron to donate

Example Problem #2 Argon has an Atomic Number of 18. Draw an atom of argon. How and why will argon react?

Example Problem #2 Argon has an Atomic Number of 18. Draw an atom of argon. How and why will argon react? 18p + 18n Since Argon has a full valence shell, it will not tend to bond to other atoms and be relatively inert

Example Problem #3 Hydrogen has an Atomic Number of 1. Draw an atom of hydrogen. How and why will hydrogen react?

Example Problem #3 Hydrogen has an Atomic Number of 1. Draw an atom of hydrogen. How and why will hydrogen react? 1p + 0n 0 - Since atoms are stable with 2 electrons in the inner most valence shell, hydrogen will tend to bind with atoms that have one electron to donate

Example Problem #4 Helium has an Atomic Number of 2. Draw an atom of helium. How and why will helium react?

Example Problem #4 Helium has an Atomic Number of 2. Draw an atom of helium. How and why will helium react? 2p + 2n Since helium has a full valence shell, it will not tend to bond to other atoms and be relatively inert

Example Problem #5 Carbon has an Atomic Number of 6. Draw an atom of carbon. How and why will carbon react?

Example Problem #5 Carbon has an Atomic Number of 6. Draw an atom of carbon. How and why will carbon react? 6p + 6n Since atoms are stable with 8 electrons in their valence shell, carbon will tend make four bonds. To do this it may form multiple bonds, including single, double, or triple bonds.

Example Problem #2 Oxygen has an Atomic Number of 8. Draw an atom of oxygen. How and why will oxygen react?

Example Problem #2 Oxygen has an Atomic Number of 8. Draw an atom of oxygen. How and why will oxygen react? 8p + 8n Since atoms are stable with 8 electrons in their valence shell, oxygen will tend make two bonds. To do this it may form two single bonds or one double bond. -
