nine electrons

Fluorine-18 is the lightest unstable nuclide with equal odd numbers of protons and neutrons, having 9 of each.

9

oxygen

Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons! This means that a neutral oxygen atom will have 8 electrons (but this number can change!

Many rich gold deposits have been found by sampling creeks for placer gold. Once gold is discovered, the prospector follows the source upstream until the gold stops, indicating that the source of gold is located there. Tracing gold to its source is the best way to find the lode sources of gold.

Can gold be found in quartz? Yes, gold can be found in quartz. It nestles in the veins (lines) or cracks in quartz and will appear as small particles or scales. In some cases you may be able to see small masses of gold within quartz but much of it is invisible to the naked eye.

the Welcome Stranger

Between all of the gold sources in the world, current estimates suggest that roughly 2,500 to 3,000 tons of new gold is mined each year. At present, experts believe that the total amount of above ground gold in the world stands at just over 190,000 tons.

Most nuggets are between 85 percent and 95 percent pure gold, but the remainder can be one of several kinds of minerals. Nuggets in laterite can be either reddish or black; nuggets in quartz appear cloaked with white.

Gold comes out of the ground in different purities, depending on the location of the mine. Typically, natural or ‘placer’ gold ranges from 65% to 98% pure, with most around 85%. Gold can also be found mixed with silver, copper, or other metals in varying percentages.

Raw Gold Purity Most raw gold is in the range of 750 parts per 1000 purity. This is the equivalent of eighteen karat (18K) gold. However, it raw gold can be as low in purity as 14K.

While they may be more expensive than your average gold bar, gold nuggets are not 24K. At most, you might be able to find a nugget that’s 21K or 22K. Pure gold just does not exist in nature—or at least, it’s exceedingly rare. The reason why you won’t find a 24K gold nugget is simple.

A natural 1 gram gold nugget containing 95% pure gold is worth $48.42, today….We buy natural gold nuggets and artificial gold nuggets.

Natural gold nuggets are never 100% pure gold. That is the short answer. Natural alloys of various metals naturally occur with gold in its natural form. The refining process is needed to remove these impurities to produce gold bullion that is truly pure.
