How easy is it to cut francium?
Francium is extremely unstable. The most stable isotope of francium has a half-life of only about 22 minutes. Other isotopes of francium have half-lives measured in microseconds. Scientists predict there is less than one ounce of francium in Earth's crust at any one time. Because of this instablilty, it would be much easier to go get a cup of coffee and wait for francium to cut itself apart.
What is the electron affinity of francium?
Francium lose one electron.
How many electrons are in the valence shell of francium?
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
How many electrons does francium have in its outer most shell?
francium only has one valence electron (one electron in the outermost shell).
How many grams in one mole?
That depends on the substance, and on whether you are considering atoms ore molecules. One mole has as many grams as the atomic or molecular mass of the substance. For example, one mole of atomic hydrogen has 1 gram; one mole of molecular hydrogen has 2 grams, one mole water has 18 grams, etc., since those numbers are the corresponding atomic or molecular masses.
How much does one mole of bromine weigh?
79.9
How much does one mole of iron weigh to the 1 decimal point?
It is 55.8 grams.
How much does francium cost for one gram?
Francium is not a commercial product.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
Does iron weigh the same as iron oxide?
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
How much does one mole of 0 weigh?
1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
How much does a mole of an ideal gas weigh?
It weights the same as one times the molar mass in g/mol. It is NOT important to be ideal, it even needn't to be necessarily a gas, only the kind of compound is important.

How much is one mole in caesium?
1 mole of caesium equal 132,90545196 g.
How much does CO2 weigh?
Carbon dioxide has a molar mass of 44.0095 grams per mole. This means that one molecule of CO2 will have a mass of 7.308 E(-23) grams.
