Cobalt has 27 protons and francium has 87 protons; 87-27=60.
What is an appropriate range for the diameter of an atom?
The smallest atom is helium (nucleus and electrons) while francium is the largest. Helium: 28 picometer francium: 260 picometer
What atom has most stable nucleus Iron or Lead?
Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
Is francium combustible?
Not known today but probably francium don't burn.

Who has the biggest nucleus in the hydrogen group?
Francium has the largest nucleus in the hydrogen group; it's always the atom in the lowest row (highest period number) of any column in a normal periodic table that has the largest nucleus in that column.
What atom has most stable nucleus Iron or Lead?
Francium has an atomic covalent radius of 260 pm, is radioactive and very unstable.
How was francium named francium?
Francium was named after France, the country it was dicovered in.

Francium has not applications and the oxide cannot be prepared.
What is the cost for 10g of francium?
Francium can form cations with the charge +1.
Is Francium radioactive?
Unstable isotopes (the stability depends on the number of protons and neutrons in the atomoc nucleus, the atomic mass, etc.) are all radioactive.
Is francium a metalliod?
Francium is a metal.
What are some things that contains francium?
Francium is a true chemical element, not an example.
Which is more reactive cesium or francium?
francium it has loads more shells around it, making them easier to be displaced because the pull off the nucleus will be less as the magnetism between the electrons and necleus is sheilded better the more full shells there is between the nucleus and outer most shell
