This caused early mappers of the periodic table‚ such as Dmitri Mendeleev‚ to think of them as proud and noble. l Carbon (C) - can take the form of one of the hardest substances (diamond) or one of the softest (graphite).And it’s made in the interiors of stars‚ though it was not produced in the Big Bang. l Helium (He) - element named after the Greek Sun God(Helios) .Helium balloon floats because Helium is lighter than air.

In 1986 in Chernobyl‚ Ukraine their Nuclear Power Plant had an uncontrolled build-up of heat and it resulted in a meltdown of one of their reactor cores. It made the graphite moderator material combust which released more than 50 million Curies of radioactivity to the environment. Nuclear power has effects on the environment through the nuclear fuel cycle‚ through operation‚ and from the lingering effects of the Chernobyl

There are a few methods to extract metals from its ores. The main ones are electrolysis (the decomposition of a compound using electricity) and heating with carbon or carbon monoxide (or called the “Blast Furnace”). Some other metals like Silver and Gold occur naturally in the Earth’s crust as “native metals”. The method to extract the metal depends on its place in the Reactivity Series (how reactive the metal is). The more reactive the metal‚ the more difficult it is to extract. Thus electrolysis

The pictures in the two-page spread above are an excellent representation of this relationship. First‚ the artwork is composed of gauche and graphite along with a digital reproduction of a Degas painting. The use of these mediums lends themselves to creating a value of light versus dark throughout the spread. On the verso page‚ the reader sees the use of gradation on the characters and frame.

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric
