an atom of calcium-40 is placed in a particle accelerator. It undergoes nuclear fusion with a neutral helium-4 atom. What new element is formed? How many protons, neutrons, and electrons are present?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
