Which is larger a hydrogen atom or francium atom?

A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.


How many more protons does francium have in its nucleus than cobalt?

Cobalt has 27 protons and francium has 87 protons; 87-27=60.


What is the bohr model for francium?

The Bohr model of the atom suggests that electrons orbit the nucleus in fixed energy levels or shells. For francium, which has 87 electrons, the electrons would be arranged in energy levels around the nucleus based on the Bohr model's principles, with the outermost electron in the highest energy level.


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 is an appropriate range for the diameter of an atom?

Rubidium cesium and francium all have one valence electron Which element has the smallest atomic radius?

Francium has the smallest atomic radius among rubidium, cesium, and francium because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of Group 1, which means it has the largest nuclear charge pulling the valence electron closer to the nucleus, resulting in a smaller atomic radius.
