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.
An atom forms an ion when it gains or loses an electron. If an atom gains an electron, it becomes a negatively charged ion (anion). If an atom loses an electron, it becomes a positively charged ion (cation).
The chloride ion is larger than the chloride atom because when an atom gains an electron to become an ion, it experiences an increase in electron-electron repulsion which causes the electron cloud to expand. This expansion leads to the ion being larger in size compared to the neutral atom.
When an electron is added to a unipositive ion, the resulting atom gains a negative charge and becomes a neutral atom. The electron neutralizes the positive charge of the ion, balancing the overall charge of the atom.
When an electron is gained, the atom becomes a negatively charged ion called an anion. When an electron is lost, the atom becomes a positively charged ion called a cation.
electron is the smallest
A hydrogen atom that does not contain a neutron is called a hydrogen ion or a proton. This ion is represented by the symbol H+. It consists of a single proton and an electron.
When a sodium atom forms an ion, it loses one electron from its outer shell. This loss of an electron leaves the sodium atom with a positive charge, as it now has one more proton than electrons. This results in the formation of a sodium ion, specifically a sodium cation with a charge of +1.
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
Ion.
atom
A neutron has no charge, so a charged atom (ion) cannot attract a neutron.
an atom that gains an electron becomes a negative ion, called an anion.

When an atom loses an electron, it loses a negative charge. This results in the atom becoming a positively charged ion.
