[I just had the misfortune of having to write an essay on Francium, for my GCSEs, so i decided to give some information on it to other people who need it for these kinds of circumstances.]
There is no more than one ounce of Francium in the Earths crust at any one time. In fact, unlike other alkali metals, it was not 'stumbled upon'. It took many years and a lot of studying to work out that there must be another group one element with a higher reactivity than Caesium. It is not possible to do any tests on Francium as it has a half life of 22 minutes but we can work out most things about it by looking at the other Group 1 metals....x...Prisca Zia...x...

Abundance of neodymium in the earths crust?
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
What is the abundance of lithium in the earths crust?
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.

crust
What percent of Earths crust do silicates make up?
Silicates make up about 90% of Earth's crust. These minerals are composed of silicon and oxygen, along with other elements like aluminum, iron, calcium, and magnesium. Silicate minerals are the building blocks of most rocks on Earth's surface.

Abundance of neodymium in the earths crust?
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
What is the abundance of protactinium?
Protactinium is so scarce that the abundance in the Earth crust was not determined.
What is the abundance of lithium in the earths crust?
Lithium is the 25th most abundant element in Earth's crust, with an average concentration of about 20 parts per million (ppm). This makes it relatively rare compared to other elements like silicon and oxygen.
How do you find the sum of fluorine?
The sum of elements like fluorine can be found by adding the atomic masses of its isotopes, weighted by their abundance in nature. The most abundant isotope of fluorine is fluorine-19, which has an atomic mass of 18.998403163 u. By accounting for the abundance of this isotope in nature, the average atomic mass of fluorine can be calculated, which is approximately 18.998 u.
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
What is neon's abundance in the earth's crust?

Quartz
What layer of the earth contains granite and basalt in the GREATEST abundance?
The crust is the layer of the Earth that contains granite and basalt in the greatest abundance. These rocks are commonly found in the continental crust (granite) and oceanic crust (basalt).
What is under the earths surface and in the earths crust?
mantle
