It does depend a fair amount on the poo particles. The smallest atom is a hydrogen atom (37 picometers) whereas some larger atoms more than 5 times larger (lanthanum is 187 picometers). If the atom is an ion, it will also change it's radius significantly (positive ions are smaller and negative ions are larger than the neutral atom).

Is measuring the size of an atom by the size of its orbital not very accurate?
No. It is the only way to measure an atom because the orbital is
the outer part of the atom and determines its size.

How is the mass of an atom determined?
The mass of an atom is determined by the size of the atom, and
the bigger the atom, the more mass it has.

What is the size of an atom?
The size of an atom refers to the typical distance from the
nucleus to the boundary of the surrounding cloud of electrons.
Asked in Chemistry
Does Electronegativity increases as the size of the atom increases?
No. Electronegativity decreases as the size of the atom
increase. As you go across a row in the periodic table, you will
see that electronegativity increases and the size of the atom
decreases. Similarly, as you go down a column you will notice that
the size of the atom increases and electronegativity decreases.

How does the size of the nucleus compare to the size of an atom?
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 happens to the size anion compared to its atom?
The size of anion increases as compared to its atom. This is due
to addition of electron.
Asked in Atoms and Atomic Structure
How is the size of an anion different from the size of the atom from which it was formed?
Anion will have more electron than which atom it was form. So,
after forming the the atom will have more electron cloud and size
will be smaller compare to the original one.
