WebJun 23, 2024 · Perhaps it's because of the way atomic volume is defined. Atomic volume is defined as the ratio of gram atomic mass to Density. That's probably why it has a different trend to atomic size. But I do not know why exactly does atomic volume follow this trend. – Michael Faraday Jun 23, 2024 at 11:26 1 WebTherefore, the radius of the atom increases as one goes down a specific group in the periodic table of elements. The size of an atom generally decreases as one moves from left to right for a certain period. In general, …

WebAn atomic radius is half the distance between adjacent atoms of the same element in a molecule. Measuring the atomic radii of chemical elements is a complicated task as the size of an atom is of the order of 1.2×10-10 m. The electron cloud forming the shell of an atom does not have any fixed shape which makes it difficult to determine the ...

WebThe atomic radius in metals is one-half of the distance between the centers of two neighboring atoms. It is one-half of the distance between the centers of bonded atoms for elements that exist as diatomic molecules.
