Not very big. The nucleus of an atom, the part containing protons and neutrons (1H, protium, consists of only a proton and an electron) takes up only a tiny portion of the atom's volume. The volume of an atom is really described by the movement of the electrons that orbit about the nucleus. Those electrons are a looooong way from the proton(s) relative to their size. A nucleus is about 10 FM in diameter. In a solid, nuclei are 1000000 or more FM apart.
Hydrogen is small compared to other atoms. To scale it up: if the proton in its nucleus was enlarged to the size of a Basketball, the electron would be some 20 miles away or so. With other atoms, the picture gets more crazy. The reality is that an atom is mostly space, and you've probably heard that. The nucleus of an atom is super tiny compared to the 95% boundary described by the outer electrons of an atom. The boundary can't be well-defined, really, because of what quantum mechanics, the uncertainty principle, and Schroedinger's wave equation have to say.

What are tiny and filled in with space - and are the building blocks of all matter?
Atoms. The nucleus of an atom (containing protons and usually neutrons) is small and dense. Electrons can be considered to be a comparatively big cloud surrounding the nucleus of an atom. In this sense, atoms are tiny but mostly contain space.
How big is a half of an apple in centimeters?
Depends on how big the whole apple was.
How do you write a sentence using the word big?
The whale looked really BIG compared to the little girl. that's how
What did rutherfords gold foil experiment provide evidence for?
He established that atoms are made of protons, neutrons and electrons.Well sir, i was just wondering the same thing. I have to do a worksheet and answer it, not so lucky for me, this was one of my big questions. If anybody would like to answer this really soon, that would be oh so very helpful.Thank you, and have a nice day. ^That is no answer, just a sorry excuseThe gold foil experiment proved that the atom is mostly empty space with a small, dense nucleus.True answer by Justin Wilkes
How can you identify a nucleus by looking at a cell through a microscope?
Two reasons: - the nucleus is stained - the magnifying power of the microscope makes small things look big
How much bigger is an atom compared to its nucleus?
The atom is about 10,000 times as big as the nucleus.
Is the nucleus of an atom big?
no
How big are the parts of the atom compared to the whole atom?
Protons and neutrons have a relative mass of one, electrons have a relative mass of 1/2000
Is the nucleus of an atom small or big?
Tiny.
How big is the vacuole in comparison to other organelles?
its big but not that big compared to the nucleus
How big the nucleus is compared to an electron?
That depends on your definition of 'nucleus'. The nucleus or core of an atom is, obviously, smaller than the atom as a whole. But seeing as you placed this question in biology, a cellular nucleus is many billions of times the size of an atom.
What describes the nucleus of an atom?
a big ball of protons and nutrons
If the nucleus of an atom were 1 mm across how many feet across would the atom be?
it would be as big as you want depending how much of the atom there is
How big is the nucleas of an atom?
Of course, as atoms are tiny the nucleus is even smaller, but it depends on the atom. Some atoms have large protons and neutons in the nucleus, others smaller ones.
How big is an atoms's nucleus compared to the cloud?
Less then half or maybe a third of the size.
How does the size of an atom compare to the size of the nucleus?
You are probably familiar with the textbook diagram of an atom that fits neatly on the page. However, the reality will get you thinking how really empty space is: If a proton were the size of a marble an electron would be about the width of a human hair. With that scale the electron's orbit would be about 2 1/2 miles away from the proton.
Which subatomic particle does not have a very big effect on the mass of the whole atom?
The electron.
