Mass: 1.67262192369(51)×10−27 kg; 938.272...
Electric polarizability: 1.20(6)×10−3 fm3
Explanation:
They are also known as more-developed countries.
They are home to 70 percent of the world's population.
two-thirds of the people live in cities and earn their income from industry.
It has something to do with the minerals in their ground.
