Beryllium is it!
No, hydrogen does not fission. Fission only occurs in heavy elements that are well past the peak in binding energy per nucleon (where binding energy per nucleon is decreasing), and fusion can only occur in light elements which are in the portion of the binding energy curve where binding energy per nucleon is increasing. When you fission a heavy element or fuse light elements, the product nuclei have higher binding energies per nucleon than the original element. This is where the energy release comes from. Check out the Wikipedia article on nuclear binding energy.
A nucleon is one of the particles that make up the nucleus of the atom. Protons and neutrons are nucleons, and the neutronis the electrically neutral nucleon.
The mass of the nucleon is decreased; the difference is released as energy.
The element with an atomic number of 40 is zirconium.
Iron
The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
We know that nickel-62 has the highest nuclear binding energy per nucleon of any element.

The mass number also refers to the nucleon number. Usually the larger number among the two present in the periodic table, the nucleon number refers to the number of protons and neutrons present within an atomic nucleus of an element.

A nucleon has more mass when it is not bound to the nucleus of an atom. When the nucleon is bound to other nucleons the binding energy that keeps them together comes from the mass of the nucleon. Therefore the mass of a single nucleon will be smaller in an atom than on it's own.
Zirconium element has 40 protons.It is a d block element.

Calcium is a metal element. Atomic mass of it is 40.
The difference between proton number (which is atomic number) and nucleon number, which is the number of protons and neutrons in an atom's nucleus, is the number of neutrons in the nucleus of a given nuclide. Nucleons are the components of an atomic nucleus. We know that both protons and neutrons make up an atom's nucleus. So the number of nucleons, which is the number of protons and neutrons, minus the number of protons, will equal the number of neutrons in the atomic nucleus.
