Ionic Charges of All Elements (List + Images inside)
Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge. When …

Arsenic
It is mainly found in minerals. The most common arsenic-containing mineral is arsenopyrite. Others include realgar, orpiment and enargite. Most arsenic is produced as a by-product of copper and lead refining. It can be obtained from arsenopyrite by heating, causing the arsenic to sublime and leave behind iron(II) sulfide.

Antimony
Antimony and its compounds were known to the ancients and there is a 5,000-year old antimony vase in the Louvre in Paris. Antimony sulfide (Sb 2 S 3) is mentioned in an Egyptian papyrus of the 16 th century BC. The black form of this pigment, which occurs naturally as the mineral stibnite, was used as mascara and known as khol.The most …

WebElements Periodic Table » Neodymium » reactions of elements
Reaction of neodymium with acids. Neodymium metal dissolves readily in dilute sulphuric acid to form solutions containing the lilac aquated Nd (III) ion together with hydrogen gas, H 2. It is quite likely that Nd 3+ (aq) exists as largely the complex ion [Nd (OH 2) 9] 3+. 2Nd (s) + 3H 2 SO 4 (aq) → 2Nd 3+ (aq) + 3SO 42- (aq) + 3H 2 (g)

size of atoms
The animations in the original were huge for the time (hydrogen was about 12 megabytes), so downloading and saving them was a wise use of bandwidth—or one could buy a CD for $37 (20 pounds). Now the videos stream and the CD seems no longer on offer. We wish we had saved one of the first edition videos, for the sake of comparison.

Nickel
Nickel resists corrosion and is used to plate other metals to protect them. It is, however, mainly used in making alloys such as stainless steel. Nichrome is an alloy of nickel and chromium with small amounts of silicon, manganese and iron. It resists corrosion, even when red hot, so is used in toasters and electric ovens.

Bismuth
Heat some bismuth in an iron ladle or porcelain bowl using a sand bath and a Bunsen burner until it melts. This happens at just 271 degree Celsius. Then turn off the burner so that the metal cools very slowly and when the metal freezes over at the top poke two holes in the solid surface and then pour out the remaining liquid and then leave ...

Valences of the Elements Chemistry Table
You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple.

Thallium
Thallium bromide-iodide crystals have also been used in infrared detectors. The addition of metals like thallium to glass can also reduce its melting point to as low as 150 degrees centigrade. As such low-melting point glasses do not shatter like normal glasses, they are particularly useful for the manufacture of electronic parts.

Solids, gases, and liquids are identified; all other species are aqueous. Reduction reactions in acidic solution are written using H + in place of H 3 O +. You may rewrite a reaction by replacing H + with H 3 O + and adding to the opposite side of the reaction one molecule of H 2 O per H +; thus. H 3 AsO 4 + 2 H + + 2 e – ↽ − − ⇀ HAsO ...

Indium iodides
Indium iodides have been known for more than a century. Indium iodide was synthesized for the first time by Meyer 1 in 1869 via the reaction of indium metal with iodine under CO 2 atmosphere six years after the discovery of indium by Reich and Richter. 2 The correct formula — triiodide InI 3 — was proposed once Mendeleev had assumed indium …

Iridium
Indium is a soft, malleable metal with a brilliant lustre. The name indium originates from the indigo blue it shows in a spectroscope. Indium has a low melting point for metals and above its melting point it ignites burning with a violet flame. Bizarrely, the pure metal of indium is described as giving a high-pitched "cry" when bent.
