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.

∙ 8y agoAn 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.

What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
What is the definition of an atomic fingerprint?
It is important to know the definition of terms in science. An atomic fingerprint is defined as the unique set of lines an element has based on its energy level.
What is the size of an atomic nucleus?
Very small
Do atomic orbitals have an exactly defined size?
No
What is the size of CO molecule?
28 atomic units
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.
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.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
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.
When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
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 atom?
Atomic size of sodium is 186
