Atomic Size is the going across any period, atomic radius is decreasing in size due to the increase in the number of electrons is attracted toward the nucleus. Going down any group, there are a large increase in atomic size. The size of an atom depends on where the electrons are distributed outside the nucleus.
Atomic size refers to the distance from the nucleus of an atom to the outermost electron cloud. It is commonly measured as the atomic radius, which represents the average distance between the nucleus and the boundaries of the electron cloud. Atomic size generally increases down a group on the Periodic Table and decreases across a period.
An atom is more than a million times smaller than the thickness of a human hair. The diameter of an atom ranges from about 0.1 to 0.5 nanometers (1 × 10-10 m to 5 × 10-10 m).
Atoms vary greatly in weight, but they are all about the same size. For example, an atom of plutonium
(one of the heaviest elements) weighs more than 200 times as much as a hydrogen atom (the lightest element), but the diameter of a plutonium atom is only about 3 times that of a hydrogen atom.
size is a measure of the size of a atom. And it usually measure by atomic radius.

Do atomic orbitals have an exactly defined size?
Atomic orbitals do not have an exact size, but rather a region where there is a high probability of finding an electron. The size and shape of an atomic orbital depend on the quantum numbers that describe it, such as the principal quantum number.
What elements has the smallest atomic size K Ca Na Ar or Kr?
The element with the smallest atomic size is Argon (Ar) as it has the highest atomic number among the options given. Atomic size generally decreases from left to right across a period in the periodic table.
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 difference between ionic size and atomic size?
Ionic size refers to the size of an ion, which can be larger or smaller than the size of the corresponding neutral atom due to the gain or loss of electrons. Atomic size, on the other hand, refers to the size of an atom, typically measured as the distance between the nucleus and the outermost electron cloud. Atomic size generally increases down a group and decreases across a period on the periodic table.
What property increases going down a group in periodic table?
Atomic size increases going down a group in the periodic table. This is because additional energy levels are being filled with electrons, leading to an increase in distance between the nucleus and the outermost electron shell.
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 was the atomic bomb nuclear?
That is by definition.
What is the atomic definition?
Atomicity is having atoms. Also the number of atoms in a molecule.
What is the Atomic size of oxygen?
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
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 of the periodic table to the bottom?
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 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.
Term for an atom that has the same atomic number as another atom but differs in atomic weight?
This is the definition of an "isotope".
What is the atomic number for fluorine17?
The atomic number for any isotope of fluorine is always 9; that is the "definition" of fluorine.
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit
What is the size of sodium's atom?
Atomic size of sodium is 186
What is nuclear energy definition?
energy derived from the atomic nucleus
