1 Super-denseTop 5 Facts: Atoms
The nucleus which is located at the heart of every atom makes up more than 99.9 per cent of its mass, but only a trillionth of its total volume.
2 Electrons are tiny
At only 1/1,836th the size of a proton or neutron, electrons contribute almost nothing to an atom’s mass, but are the most active component of an atom, responsible for bonding.
3 The rest is filler
More than 99.9 per cent of an atom’s volume is empty space. If an atom’s nucleus were the size of a basketball, its electrons would be zipping around several miles away.
4 The quantum leap
When electrons jump between energy levels, they don’t move through the space between. Instead, they disappear from one level and then instantly reappear on another level.
5 The force is strong
Atomic nuclei are held together by the strong force, which is 1038 times stronger than gravity, but only operates on the minute scale of a nucleus.

    ‘We take a look at the five largest animals of all time’ Nope. Despite most of them apart from the whale being debatable, the fact the mountain gorilla at 200kg is obviously not one of the five largest animals of all time (what about other types of bear? elephant? or rhinos, hippos and countless others)

    Apologies, we were referring merely to five of the largest animals of all time, not specifically the five largest.
