Pressure, can compact the atoms in gases to make them closer and in which case more react-able.
The mass of a proton = 1.6726219 × 10^-27 kg.
It’s almost the exact same number as the mass of a neutron, which is 1.674927471×10^-27 kg. The mass of an electon is much less, even negligible.
I hope this helped you out!
