There is a pair of converging reasons why measuring the size of an atom is difficult. One is that the atom is so small, and the other is that the tools to do that have a limited ability to measure things as small as an atom with a high level of accuracy. They may be the same reason. and bye
covalent bonds a bond (any type of bond, but JUST the word bond!)
If you think to molecules or atoms the answer is yes.
It is called a GAS. Gases have no definite volume (can be compressed) and no definite shape
compound
Nothing on the subatomic level is entirely definite, as described by Heisenberg's Uncertainty Principle, but within the limits of that uncertainty, yes, neutrons have a definite shape (spherical) and volume (which is very small).
Yes, atoms have a definite volume.
A liquid has a definite size but no definite shape. In contrast, a solid has definite size and shape, and a gas has no definite size or shape.
A solid has both a definite size and shape. A liquid has a definite size but no definite shape. A gas has neither a definite size nor shape.
water
A crystal.
No, but it does have a definite volume.
the minimuim size
Plasma is made up of free electrons and atoms that are stripped of their electrons. It has no definite shape or volume. A Solid has a definite shape and a definite volume. A Liquid has no definite shape but has a definite volume. A Gas has no definite shape or volume.

yes atoms do double in size however atoms in helium are smaller because oxygen atoms double in size.
A gas does not have a definite shape and does not have a definite volume because a gas can change its volume. Its atoms and molecules move around fast and spread out easily when the space between the atoms and molecules increases.
