Atomic Radius of Chemical Elements - Material Properties
A thorium atom has 90 electrons, of which four are valence electrons. Four atomic orbitals are theoretically available for the valence electrons to occupy: 5f, 6d, 7s, and 7p. Despite thorium's position in the f-block of the periodic table, it has an anomalous [Rn]6d 7s electron configuration in the ground state, as the 5f and 6d subshells in the early actinides are very close in energy, even more so t… WebElement Thorium (Th), Group 20, Atomic Number 90, f-block, Mass 232.038.
