Iron (Fe) is an example of a transition element that has relatively easy-to-remove electrons due to its electronic configuration. Transition metals like iron have partially filled d-orbitals, which allow them to lose electrons more readily, facilitating various oxidation states and chemical reactions. This characteristic makes them vital in many industrial processes and biological functions.
Iron (Fe) does not belong in the noble gases because it is a transition metal, not a noble gas. Noble gases have a full outer electron shell, making them stable and unreactive. Transition metals like iron have partially filled d or f orbitals, and they can form ions and participate in chemical reactions.
A lot!! 850 moles iron (6.022 X 10^23/1 mole Fe) = 5.12 X 10^26 atoms of iron
Transition metals are elements that have partially filled d or f orbitals. Some common transition metals include iron (Fe), copper (Cu), and silver (Ag). These metals show characteristic properties such as the ability to form colored compounds and variable oxidation states.

4,80 moles of Fe contain 28,9062761136.10e23 atoms.
To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
To determine the number of atoms in 10g of Fe, you first need to calculate the number of moles of Fe using its molar mass (55.85 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in those moles of Fe. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 10g of Fe.
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
To find the number of moles, you need to divide the number of atoms by Avogadro's number, which is about 6.022 x 10^23 atoms/mol. So, 5.98 x 10^24 atoms of iron would be approximately 9.93 moles of iron.
