They are both extremely reactive. They react spontaneously with air, water, and even the weakest of acids.

What metal is found naturally as an element?
Gold, silver, copper, iron, lead, mercury.
What is the most common salt found in ocean water A potassium B calcium carbonate C magnesium D sodium chloride A potassium B calcium carbonate C magnesium D sodium chloride?
That would be D. sodium chloride.
Why are gold and silver not found as an ore?
Because silver and gold are native metals that are found in its pure form as they are unreactive!
Why is sodium not found in nature in its elemental form?
Sodium is (like all alkali metals of group 1) far to reactive with oxygen and even water (explosive burning oxidation reaction).
What does monovalent ion mean?
A monovalent ion is a cation that only has one valence electron to form an ionic bond with something else. Typically they are the alkali metals--Lithium, Sodium, Potassium, Rubidium, Caesium and Francium. Some transition metals can be found to be monovalent ions.
What native metals can be found in the earths crust?
native metals
Why is gold often found as a metal in the ground?
Metals found native in the ground are metals which are so unreactive that they are still found unchanged or "native"
What are the names of three metals from the periodic table of the elements?
Calcium. Potassium. Sodium. All are part of your daily diet found in milk for Calcium, bananas for Potassium, and salt for Sodium. Calcium strengthens bones and Potassium can cause heart failure in high amounts. Dangerous Sodium must be mixed with deadly Chlorine to form the Na-Cl compound, which is safe for human consumption.
What are two important electrolytes found in blood plasma?
Two important electrolytes found in blood plasma are Na+ (sodium) and Cl- (chloride).
What metal is found naturally as an element?
Gold, silver, copper, iron, lead, mercury.
Where are the alkali metals?
The alkali metals are the metals found in group I, includinng lithium, sodium, potassium, rubidium, caesium and francium.
Which native metals are found in a pure form?
Gold
What mineral ions are found in milk?
Pottasium,calcium,magnesium and sodium
Which salt found in sea in more quanitty sodium chloride or calcium?
Of course sodium chloride is more in the sea.
Where in a heart cell is calcium normally found?
Calcium is normally found out side of the cardica muscle cell, aswell as sodium. These can be found in large amounts. inside the cell is where potassium can be found.
What Are Metals Manufactured From?
A few metals are found 'native', that is as the metal and only need separating from the surrounding materials, e.g. gold and silver. Most metals have to be chemically extracted from whatever compounds we can find. Iron is often found as its oxide and is extracted by heating with coke and limestone in a blast furnace. Sodium is found as sodium chloride and we obtain it by electrolysis of the melt. The method used depends on what will work and what it costs. Methods include displacement by carbon (coke), displacement by another metal, and electrolysis.
What two unreactive metals are found native?
Gold, Silver
