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

∙ 7y agoAtoms comprise a very small nucleus which is surrounded by a cloud of electrons. The electrons do not have fixed positions and can move between different shells depending on their energy levels. Since it is the outermost electrons which are most likely to move up of down the excitation states, the overall size of the electron will change.

Do the gas particles have a definite shape?
If you think to molecules or atoms the answer is yes.
What form of matter has no definite size or shape?
It is called a GAS. Gases have no definite volume (can be compressed) and no definite shape
What are two or more different atoms are combined in definite proportions in any?
compound
How can you describe a gas?
They are made of gas, obviously, and not dirt; They all contain rings; they have deep, massive, atmospheres.
What consisits of 2 or more atoms joined in a definite ratio?
covalent bonds a bond (any type of bond, but JUST the word bond!)
Do atoms have definite volume?
Yes, atoms have a definite volume.
Which state of matter has a definite size but no definite shape?
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.
How do you know if matter is a solid or a liquid?
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.
What has no definite size and no definite shape?
water
What is a solid with a definite shape and whose atoms are arranged in a definite repeating pattern?
A crystal.
Does gas have definite mass?
Yes. Gas Mass = sum of gas atoms= n(gas atoms).
Does matter in liquid form have definite size and shape?
No, but it does have a definite volume.
How is plasma different?
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.
What is the meaning of definite form of size?
the minimuim size
Do atoms in oxygen double in size?
yes atoms do double in size however atoms in helium are smaller because oxygen atoms double in size.
Has a definite size and shape?
Solids have a definite shape and size. This is where solids differ from liquids and gases, for which the same cannot be said.
Does gas have a definite volume and shape?
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.
