In small atoms, from hydrogen to sodium, the binding energy per nucleon increases with an increasing atomic number. This is because each additional nucleon is attracted by other nearby nucleons, and thus more tightly bound to the whole.

In normal conditions, atom nuclei don't fuse spontaneously. The nucleus is positively charged and electrostatic forces will repel each other long before they come so close that strong nuclear forces can start to act and bind nuclei together.
