Explanation The given Lewis structure is, Figure 1 In the Lewis structure, a solid line indicates a bond formed by sharing of two electrons between the two atoms and dots show unshared electrons or lone pairs. So each atom contributes one electron for the formation of a single bond. Number of valence electrons of each atom is calculated by adding its unshared electrons and shared electrons. Element A has three pair of unshared electrons and one electron is shared with element D . So, it has 7 valence electrons and hence belongs to group 7 A or 17 . Also it is from the first two rows of periodic table, hence it must be fluorine ( F ) . Element D has no unshared electron and it forms four bonds sharing one electron each with element A, Q and 2 electrons with element E . So, it has 4 valence electrons and hence belongs to group 4A or 14 . Also it is from the first two rows of periodic table, hence it must be carbon ( C ) . Element Q has one pair of unshared electrons and it forms three bonds sharing one electron each with element D, X and Z

Actinides

The elements in which the extra electron tends to enter the 5f-orbitals of (n–2)th main shell are considered 5f-block elements. They are also named actinides. Actinides include 15 elements, from atomic number 89 to 103.
