About 1 Angstrom.
The smallest atom is hydrogen.
The width of a silicon atom is about 0.117 nanometers. In comparison to other atoms, silicon atoms are larger than hydrogen and helium atoms, but smaller than atoms like carbon and oxygen.
the atom with the least mass is the hydrogen atom
There is one atom of hydrogen in a hydrogen molecule.
A hydrogen ion can change into an atom by gaining an electron. When a hydrogen ion, which is essentially a hydrogen atom that has lost its electron, gains an electron back, it will become a neutral hydrogen atom.
There is one atom in a hydrogen atom
yes the smallest atom is hydrogen
