Alkali metals have only one valence electron and so have low binding energy to the metallic crystal lattice. ... A lower amount of energy needed to break a bond means a lower melting/boiling point.
Upwelling
Explanation:
The rise of deeper water to the surface is called upwelling.
Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.
- This occurs usually along the short where wave action is very prevalent.
- Surface wave pushes away warm water.
- Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
- This nutrient rich water supports biological activities because they are rich.
- Wind along the coast can also force surface water down.

<em>What volume do 5 moles of a gas occupy at 28 ° C and 3 atm of pressure?</em>
<em />
<h3>Further explanation</h3>
In general, the gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08206 L.atm / mol K
T = temperature, Kelvin
n= 5 moles
T=28 +273=301 K
P=3 atm
The volume of the gas :
The bottom of group 1. Francium (or Fr) is the element with the greatest metallic properties.
Francium is not a naturally-occurring element, however. It is man-made. There is an isotope of francium that exists naturally, but it's half life is so short that it decays almost instantly into a different element.
The naturally-occurring element with the highest metallic properties is cesium (or Cs), located right above francium.
Metallic characteristics decrease as you move from left to right on the periodic table.
