The critical part of the red blood cell is a protein called hemoglobin. Hemoglobin combines with oxygen and carbon dioxide, transporting these gases from one location to another in the body. Hemoglobin is a relatively large molecule, with a mass of about 65,000 u. The crucial atom in the hemoglobin protein is iron.Similarly one may ask, what is the element HB?
Hemoglobin is composed of four elements- carbon, hydrogen, oxygen and nitrogen.
Likewise, what is period 4 on the periodic table? Period 4 includes the biologically essential elements potassium and calcium, and is the first period in the d-block with the lighter transition metals. Completing the fourth period are the post-transition metals zinc and gallium, the metalloids germanium and arsenic, and the nonmetals selenium, bromine, and krypton.
Keeping this in consideration, what is Hg on the periodic table?
The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means "liquid silver" — to reflect its shiny surface. The element is also known as quicksilver for its mobility.
What is the name of 119 Element?
eka-francium
What does C stand for on the periodic table?

What is s in chemistry?
Often chemical equations are written showing the state that each substance is in. The (s) sign means that the compound is a solid. The (l) sign means the substance is a liquid. The (aq) sign stands for aqueous in water and means the compound is dissolved in water. Finally, the (g) sign means that the compound is a gas.What is an isotope symbol?
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. Additionally, N=A−Z.What are the first 118 elements?

What does N stand for in chemistry?
N, the chemical symbol for the element nitrogen. N or Asn, the symbol for the common natural amino acid asparagine. N, the Normality (chemistry) or chemical concentration of a solution. N, the neutron number, the number of neutrons in a nuclide.What attracts mercury?
Mercury is a heavy, silver-white element that is liquid at room temperature. While the clumps of soil break into particles smaller than sand, the copper pellets, containing a small amount of magnetic metal, attract the mercury from the particles.Is mercury a liquid?
Mercury is the only metal that is a liquid at normal temperatures and pressure. Because of the behavior of the valence electrons, mercury has a low melting point, is a poor electrical and thermal conductor, and doesn't form diatomic mercury molecules in the gas phase.What is Group 12 on the periodic table called?
Group 12, by modern IUPAC numbering, is a group of chemical elements in the periodic table. It includes zinc (Zn), cadmium (Cd) and mercury (Hg). Formerly this group was named IIB (pronounced as "group two B", as the "II" is a Roman numeral) by CAS and old IUPAC system.Is gold on the periodic table?
Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.Is Mercury magnetic?
At room temperature, the element mercury is not very magnetic at all. It has a very small, negative magnetic susceptibility, meaning that when you put mercury in a magnetic field, it magnetizes just a little tiny bit in the opposite direction. We say that mercury is a weakly diamagnetic substance at room temperature.Is Mercury flammable?
Mercury is non-combustible. The agent itself does not burn, but it may react upon heating to produce corrosive and/or toxic fumes. Fire will produce irritating, corrosive, and/or toxic gases. Use an extinguishing agent suitable for the type of surrounding fire.Why is gold called AU?
Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek.What kind of element is mercury?
Mercury is a shiny, silvery, liquid metal, sometimes called quicksilver. It is a transition metal with atomic number 80 on the periodic table and an atomic weight of 200.59, and its element symbol is Hg. While it's an extremely rare element, there's a world of interesting information about mercury.Is mercury still used today?
Today, mercury is used for the manufacture of industrial chemicals and for electrical and electronic applications. But although mercury has such widespread use, it has long been known to be highly toxic in both liquid and gaseous forms, causing brain and/or liver damage if ingested, or with prolonged exposure.Is osmium malleable?
This element is a solid. Osmium is classified as a "Transition Metal" which are located in Groups 3 - 12 of the Periodic Table. Elements classified as Transition Metals are generally described as ductile, malleable, and able to conduct electricity and heat.What is a period number?
A period number is the number that is given to a group of elements across the periodic table that have made a round from completing its outer electron shell. This pattern usually begins with a Group I element and ending with a Group 8 element. So for example, period I would be from hydrogen to helium.
