All halogen compounds are soluble except those containing Ag+, Hg2+, or Pb+2)

Page 8: Where are the elements How did they form? Earth Water Air Living Things

All nitrates (NO3-), chlorates (ClO3-) and

perchlorates (ClO4-) are soluble.

Most sulfates (SO42-)

are soluble.

Calcium sulfate is slightly soluble.

Do the abundance of the elements change? In other words, do elements change into other elements?

Are elements formed in the caldron of a volcano?

Are elements changed to other elements in the intense heat of a volcano (about 1,000oC for lava and 2,000oC for inside volcano)?

Page 29: Where are the elements How did they form? Earth Water Air Living Things

Elements may separate from other elements or combine with certain elements. There is not enough heat in a volcano to change an element into another element.

Here is silicon and oxygen with trace amount of metals (darkening) to form a mineral called…

The core with a mass of ½ million Earths shrinks from 1000 km (600 mi.) to about 50 km (31 mi.) in 1 second. Implosion velocity reaches 170 million mph...about 1/4 c or 50,000 miles per second.

The outward moving matter is moving so fast that it compresses and heats whatever it collides with to temperatures of 1010 to 1011 K... much hotter than anything we have encountered in our studies of stars so far.

Such enormously high temperatures generates nuclear reactions. Below the neon shell source, the oxygen and silicon is converted to iron plus less massive nuclei such as argon, calcium, potassium, titanium, copper, and zinc. By the time the blast reaches the outer shell sources, the collisions are less violent and the temperatures reached are too low for nuclear reactions.

Page 53: Where are the elements How did they form? Earth Water Air Living Things

• Thus, nuclear reactions account only for elements less massive than iron. What about the rest of the periodical table? Where do the other elements with more than 25 or so protons in their nuclei come from?

• The source of neutrons for neutron capture is the outer half of the collapsing neutron core that was ejected.

• The environment for neutron capture only last a short time. Consequently, not many of the heavy elements arecreated.

Supernovas often become black holes. The remaining core of neutrons with about the weight of 3 to 15 of our suns has gravity so strong that light cannot exit.

There is one black hole in our galaxy that has the mass of 2.6 million Suns.

Where did hydrogen come from?

• It all depends on how good your math is.

• Test: How far do you travel in 2 ½ hours, if you are going 120 mph?

• If you left home at noon and traveled 60 mph, how long would it take you to drive 300 miles?

More light elements fused as neutrons compresses layers that reach temperatures up to 100 billion degrees. Heavy elements form as nuclei absorb neutrons.
