Atomic size is defined as the distance between the nucleus and the outermost electron in an atom. Since electrons occupy regions of space called orbitals, which have fuzzy boundaries, it is difficult to pinpoint an exact boundary of an atom. Additionally, the electron cloud distribution is not uniform, making the atomic size less precise.

Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
What form of matter has no definite size or shape?
Gas is a form of matter that has no definite size or shape. Gas particles are free to move and fill the entire space available to them.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
What is similar in convergent plate boundary ocean to ocean and convergent plate boundary continent to continent?
They are the same size
What is the size of the atmosphere?
Earths atmosphere? 300 miles. There is no definite boundary.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
What is the atomic radius of a chemical element?
The atomic radius, is the measured size of the atoms of a chemical element. Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.
Which state of matter has a definite size but no definite shape?
A liquid is the state of matter that has a definite volume but no definite shape. It takes the shape of its container.
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
Is the atomic size of francium greater than that of cesium?
Yes, the atomic size of francium is greater than that of cesium. Francium is located below cesium in the same group on the periodic table, so as you move down the group, atomic size generally increases.
What is the Size of carbon atom?
The size of a carbon atom can be described in terms of its atomic radius, which is about 70 picometers (pm) or 0.7 angstroms. This is the distance from the nucleus to the outer boundary of the electron cloud in a carbon atom.
Does matter in liquid form have definite size and shape?
No, but it does have a definite volume.
What is the meaning of definite form of size?
the minimuim size
Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
Why is a boundary surface diagram useful in representing an atomic orbital?
A boundary surface diagram illustrates the regions in space where an electron is likely to be found in an atomic orbital. This visual representation helps in understanding the shape and size of the orbital without getting into complex mathematical equations. It provides a clear depiction of the probability distribution of finding an electron in a given region.
