In scientific terms what do America, India and France have, that Russia, Pakistan and England do not?
America, India and France have names similar to elements in the periodic table. The other named countries do not.
Americium is a synthetic element that has the symbol Am and atomic number 95.
This transuranic element of the actinide series is located in the periodic
table below the lanthanide element europium, and thus by analogy was named
after another continent, America.
Indium is a chemical element with chemical symbol In and atomic number 49.
This rare, very soft, malleable and easily fusible post-transition metal
is chemically similar to aluminium. Indium was discovered in 1863 and
named for the indigo blue line in its spectrum that was the first indication
of its existence in zinc ores, as a new and unknown element.
Francium is a chemical element that has the symbol Fr and atomic number 87.
It is named after the country in which it was first found, that is France.
