Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events. Links are provided below to Related questions that will help you sort this out.
The fission of a Uranium 235 nucleus gives rise to an average of 2.5 neutrons per fission (fission can occur with a range of different fission products which accounts for this number not being a whole number). Gamma radiation is also emitted.
no, alpha decay.
The neutron
Hydrogen is not changed into helium in nuclear fission. In nuclear physics, nuclear fusion is a reaction in which two or more lighter atomic nuclei are forced together and are fused into a heavier nucleus. In the case of the formation of hydrogen into helium, our sun does that in what is called the proton-proton reaction.
Helium is obtained as a byproduct of methane extraction.
Beta radiation does not have a helium nucleus.Alpha radiation, however, does have a helium nucleus.
Helium has two valence electrons, it has completely filled s orbital and has stable electronic configuration. Hence it is chemically inert
In alpha decay decay two neutrons and two protons are released from the nucleus and an alpha particle (an Helium nucleus) is released: the atom's nucleus changes in to that of a nucleus two place earlier in the periodic table (Proton number falls by 2, Nucleon number falls by 4) In spontaneous fission a heavy, unstable nucleus autonomously disintegrates and falls in to two smaller nuclei (daughter nuclei) of a similar mass and a few (depending on the nature of the fission) neutrons are released with high kinetic energy.

The nucleus will probably instantly fission into three helium nuclei and a shower of six neutrons.
No. Hydrogen is the simplest and lightest element with the nucleus consisting only of a single proton. There is no smaller nucleus you can make. The only nuclear reaction hydrogen can undergo is fusion into helium.

It can eject anything, depending on the particular nucleus and the reaction involved, ranging from alpha (Helium nucleus) to beta (electron or positron), gamma (photon/energy) to neutron. If it splits, then it can "eject", so to speak, mixed fission byproducts, which encompasses a wide range of nuclei.
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
Positively charged helium atoms deprived of electrons. (2 protons 2 neutrons)
