Verified step by step guidance1
Understand that each element in the periodic table is represented by a unique one- or two-letter chemical symbol, usually derived from its English or Latin name.
Recall that francium is an element located in period 7 and group 1 of the periodic table, and its symbol is derived from the first two letters of its name.
Check the options given: 'Fa', 'Fe', 'Fr', and 'F'. 'Fe' is the symbol for iron, and 'F' is the symbol for fluorine, so these can be eliminated.
Recognize that 'Fa' is not a valid chemical symbol for any element, while 'Fr' correctly represents francium.
Conclude that the correct symbol for francium is \(\text{Fr}\), following the standard convention of element symbols.
