How does a negative ion differ from an uncharged atom of the same element?
Katena32 [7]
When an atom or molecule accepts or looses an electron or electrons it gets either negative charge (when electrons gained) or a positive charge (when looses electron). The negative ion is called Anion and positve ion is called the Cation. An Ion can be Atomic or Polyatomic.

Example:
              Sodium when looses one electron forms a cation i.e. Na⁺

              Chlorine when gains one electron forms an Anion i.e. Cl⁻

Result:
          <span>A negative ion (Anion) differ from an uncharged atom of the same element in the number of electrons. An anion contains more electrons than its corresponding Neutral Element.</span>

Can someone tell me a summary of volcanoes and plate tectonics? (Please quickly!)
slamgirl [31]
TECTONIC PLATES

a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
VALCONES AND TECTONIC

Most volcanoes form at the boundaries of Earth's tectonic plates. These plates are huge slabs of the Earth's crust and upper mantle, which fit together like pieces of a puzzle. These plates are not fixed, but are constantly moving at a very slow rate. They move only a few centimeters per year.
