What is the atomic number of francium?
The atomic number of francium (Fr) is 87.The atomic weight of Fr is 223 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Why is francium the most explosive element on the periodic table?
Francium, with atomic number 87, does not have the highest atomic number. When it was discovered, in 1939, scientists already knew of five elements with higher atomic numbers: radium (88), actinium (89), thorium (90), protactinium (91) and uranium (92). By the end of 2015, the highest atomic number was 118 - for ununoctium.
What is the atomic mass of francium?
The atomic mass of francium is approximately 223. It is a highly radioactive element and the heaviest known alkali metal.
What does Fr stand for in periodic table?
Fr = Francium - the chemical element of atomic number 87, a radioactive member of the alkali metal group. Francium occurs naturally as a decay product in uranium and thorium ores.
How many electrons does Francium have?
There are 87 electrons is Francium. There are also 87 protons, 87 neutrons and, by extension, the atomic number is also 87.
Francium's atomic number?
7 is the atomic number of francium.
What is the numerical value of francium?
The atomic number of francium is 87.
What number is francium on the periodic table of elements?
The atomic number of francium is 87.
How is the element francium you?
Francium is the chemical element with the atomic number 87.
What is the atomic number of francuim?
Francium is a non meta element. Atomic number of it is 87.
What is the atomic number of francium?
The atomic number of francium (Fr) is 87.The atomic weight of Fr is 223 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Is 223 the atomic weight number of francium?
Yes.
What is element with atomic number 87?
Francium is a non meta element. Atomic number of it is 87. It is unstable.
Suppose a new element is added under francium in the periodic table what would its atomic number be?
If a new element is added under francium in the periodic table, its atomic number would be 119. Francium has an atomic number of 87, so the next element in the periodic table would be the one with an atomic number of 88, which is radium. The subsequent element would have an atomic number of 119.
Why is francium the most explosive element on the periodic table?
Francium, with atomic number 87, does not have the highest atomic number. When it was discovered, in 1939, scientists already knew of five elements with higher atomic numbers: radium (88), actinium (89), thorium (90), protactinium (91) and uranium (92). By the end of 2015, the highest atomic number was 118 - for ununoctium.
How many electrons are in francium?
The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)
What is the atomic mass of francium?
The atomic mass of francium is approximately 223. It is a highly radioactive element and the heaviest known alkali metal.
