The element Sodium will
form a +1 cation, while the bromine a -1 anion. Since the anion bromine is
always a liquid, therefore its symbol is Br2(l). So, the chemical equation for
their reaction is: <span>
<span>2Na(s) + Br2(l) -> 2NaBr(aq) </span></span>
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>
Answer:
Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.
The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-
- The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.
- The eruption led to the releasing of a large number of volcanic gases into the atmosphere.
- The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.
A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface
Answer:
