What is atomic structure of iron?
A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus. As with other transition metals, a variable number of electrons from iron’s two outermost shells are available to combine with other elements.

What type of element is thorium?
actinoid series
thorium (Th), radioactive chemical element of the actinoid series of the periodic table, atomic number 90; it is a useful nuclear reactor fuel. Thorium was discovered (1828) by Swedish chemist Jöns Jacob Berzelius. It is silvery white but turns gray or black on exposure to air.

How do you calculate iron atoms?
1 Answer
- 1 mole of iron = 56 gm (Gram atomic mass of iron)
- 1 mole of iron element contains 6.022 × 1023 atoms of iron.
- So, 56 gm of iron = 6.022 × 1023 atoms.
- 2.8 gm of iron = (6.022 x 1023)/56 x 2.8.
- = 3.011 × 1022 atoms.
What color is thorium metal?
silvery white
Is thorium metal or non metal?
When pure, thorium is a silvery white metal which is air-stable and retains its lustre for several months.
What element has the electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 4?
According to the periodic table, this element is sulfur.
What is the electron configuration of thorium?
Thorium atoms have 90 electrons and the shell structure is 2.8.18.32.18.10.2. The ground state electron configuration of ground state gaseous neutral thorium is [Rn].6d 2.7s 2 and the term symbol is 3F 2. Schematic electronic configuration of thorium. The Kossel shell structure of thorium.
What is the symbol for thorium?
Thorium Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft, malleable, and has a high melting point.
What is the binding energy of thorium?
Electron binding energies for thorium. All values of electron binding energies are given in eV. The binding energies are quoted relative to the vacuum level for rare gases and H 2, N 2, O 2, F 2, and Cl 2 molecules; relative to the Fermi level for metals; and relative to the top of the valence band for semiconductors.
When was thorium added to the periodic table?
In the periodic table published by Dmitri Mendeleev in 1869, thorium and the rare-earth elements were placed outside the main body of the table, at the end of each vertical period after the alkaline earth metals.
