It is widely used in the human body where it is important in oxygen transport in hemoglobin.

Iron is widely used in construction especially the manufacturing of steel.

The unit of density is gr/cm3 (grams per cubic centimeter) for solids and gr/l (grams per liter) or kg/m3 (kilograms per cubic. The first chemical element with the lowest density is Hydrogen and the highest density is Osmium. Therefore, a chromium atom contains twenty-four protons. We must always remember that the atomic number and the number of protons of an element are equal. Since chromium is the 24th element of the periodic table, the atomic number of chromium is 24. One third of the Earth’s mass is iron, believed to be in the core producing magnetic poles at North and South. For chemistry students and teachers: The tabular chart on the right is arranged by Atomic number. The elements in the periodic table are arranged according to their atomic number. 4s1 and the term symbol of chromium is 7S3. The ground state electronic configuration of neutral chromium is Ar. Chromium atoms have 24 electrons and the shell structure is 2.8.13.1. Iron is a well known magnetic compound due to its unpaired electrons. Group name: (none) Period in periodic table: 4. Iron’s symbol is Fe after the Latin ‘ferrum’ meaning iron. of protons in an atom is referred to as the atomic number of that. It was around 1000BC that molten Iron and carbon were mixed together to produce the alloy of steel. French chemist incorrectly declared that del Rios new element was only impure chromium. The atomic number of each element increases by one, reading from left to right. Period A horizontal row in the periodic table. Iron artifacts have been found dating to 5000 BC and it is known that between 1300-1200BC Iron was easily smelted by humans and replaced bronze as the common metal for making weapons and armour. Members of a group typically have similar properties and electron configurations in their outer shell. Iron is an element that has been known since ancient times and has been an important part in the develop of humans. It is a Transition metal and located in Group 8 of the periodic table. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals.Iron (Fe) is a grey metal that has the atomic number 26 in the periodic table. Please note that the elements do not show their natural relation towards each other as in the Periodic system. The electronic configuration for chromium is: (Ar)(3d) 5 (4s) 1, and it has an atomic radius of 0.130 nm. The unit of density is gr/cm3 (grams per cubic centimeter) for solids and gr/l (grams per liter) or kg/m3 (kilograms per cubic) for gases Chromium, Cr: Index: Chromium is a metal in group VIB of the periodic table with atomic number 24, an atomic weight of 51.996, and a density of 7.19. Total number of protons in the nucleus is called the. This list contains the 118 elements of chemistry The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic number. Chromium is a chemical element with atomic number 24 which means there are 24 protons in its nucleus.
