Transition Metals: Chromium

The melting point of Gallium is about 85 degrees fahrenheit, just above average room temperature. its unique melting point allows it to melt in one's hand, then re-solidify when removed. Gallium more than likely will supercool below its freezing point. It is one of the metals, like mercury, that is able to be liquid at room temperature, and therefore be used in metal-in-glass high-temperature thermometers. Unlike mercury though, it has a low vapor pressure at high

Chromium – A mineral that supports your healthy blood sugar levels, your immune system, your lean body mass, and your heart health.

First energy level: 2 Second energy level: 8 Third energy level: 18 Fourth energy level: 2 Total energy level: 30 Where is Zinc located in the Periodic Table ??? Zinc can be found in Period 1 and Group 4 on the periodic table ( In red at the bottom) This is because of the atomic number that zinc contains and therefore that is why zinc is placed in that order in the periodic table Similarities and differences between the compound ‘Zinc Sulphate’ and the element ‘Zinc’ Similarities and differences between the compound ‘Zinc Sulphate’ and

Chromium based paints are usually orange, yellow, or green and are chromium oxides. The chromium ion in this case is the trivalent chromium. Trivalent chromium in this form oxidizes over time, as a result of being continuously exposed to air, to hexavalent chromium, and as the paint erodes, the hexavalent chromium can end up in soils, groundwater, and even air as

The element I have received for my mini project is Nickel (Ni). Nickel is a metal element that is found on period 4, and group 10 in the periodic table. Nickel has a lot of background information behind it like it is considered to be corrosion-resistance. Nickel is known to have 28 electrons and 28 protons its atomic number is also 28. Pure nickel is rarely found on earth and the first pure nickel coin was made in 1881, It also is highly toxic to humans and causes skin allergens, and Russia is the largest producer of nickel.

The main component that make up an atom are protons, electrons and neutrons. Protons are positively charged. While electrons are negatively charged. Neutron is not like a proton or an electron. It isn't like proton or an electron because a neutron does not have a charge. They are arranged by the atomic number. The atomic number is the number of protons in the nucleus of an atom and the electrons are arranged in levels. The atomic number is the small number that is at the top left corner of the element in the box. Copper has twenty nine electrons and twenty nine protons. Copper has two isotopes. Which are copper 63 and copper 65. Their compositions of copper 63 and 65 are stable. The abundances of copper 63 is 69.15 percent and copper 65 is

Calcium, Na, is a metal located the 20th element in the periotic tablet and has an atomic mass of 40.078. It is located in period 4 group 2 and is a alkaline earth meatal. These metals are shiny, and most are white or silvery in color, physically they are soft, they react with water to produce hydrogen gas and the metal hydroxide. Due to their high levels of reactivity, the alkaline earth metals rarely appear by themselves in nature.

The name Krypton comes from the Greek word krytos which means hidden. The atomic symbol for the element in the periodic table is Kr. The atomic number is 36, which means the number of protons or electrons in the nucleus. The average weight is 8.738 in atomic weight units. The number of Neutrons it contains is 48. The gas density is 3.749 g/liter at 0 C. The melting point for the element is -157.20 °C and its boiling point is-153.2 °C. Krypton is a colorless, odorless, and tasteless element.

Today, most Strontium is produced for manufacturing of color television tubes. It can be used to purify Zinc. It can be combined with iron to make magnets. Strontium is that one element that gives road flares

The atomic number for vanadium is 23. The melting point is 1910 Degrees Celsius. The boiling point is 3407 degrees Celsius. The atomic mass is 50.9414 it also looks like aluminum but

Mercury is a transition metal that is also known as “quicksilver.” No one is sure who discovered this element. Mercury has been used since ancient times; the Chinese, Egyptians, and the Hindus have been known to use mercury. In 1500 B.C. mercury was found in ancient Egyptian tombs. There also has been writings found that have said “liquid-silver” and “water-silver” written by Aristotle in the fourth century B.C.

While most metals do have very high boiling points, just as gallium does, most metals do not begin to melt at such a low temperature. This is one of the things that makes gallium so special, because it has one of the widest ranges between melting and boiling point of any element.

What is the element: The element is titanium. Titanium is a transition metal. The atomic number is 22. The atomic mass is 47.867. It has a melting point of 3,034℉. The color of this element would me a silver color.

Ever since its discovery in 1804 by William Hyde Wollaston it has always held the status as a fairly ordinary element. Rhodium was discovered when Wollaston was working in his lab in England, studying an ore of platinum from South America. He found a rose coloured compound on the ore, and later discovered that it was Rhodium chloride. “The name Rhodium was chosen because of the rose colour. In greek rhodon means rose.” said Brian Payne in a press conference regarding the missing Rhodium “However we want everyone to know that pure Rhodium is not rose coloured, and it is lustrous and silvery white” he continued. Ever since its discovery the rare and elusive Rhodium has been used in many things in our everyday lives. Sadly the main use of Rhodium does not involve using its shiny lustrous property. 80% of all Rhodium mined, and extracted from platinum ore is used in catalytic converters in cars in order to reduce harmful pollution from exhausts. Rhodium is also used as an alloying agent to harden, and improve corrosion resistance of Platinum and Palladium. Nevertheless some Rhodium still gets to display is shine in certain uses. Rhodium is used on jewelry to give it the highly sought after platinum look, and for mirroring light in bright searchlights.

Transition metals, such as iron, copper, zinc, nickel, and cobalt, play vital roles in numerous
