Question

Elements are arranged in groups by similar atomic structure on the periodic table. This allows for an element's properties to be predicted based on general periodic trends. One of these trends, atomic radius, increases down a group and to the left along a period and can be defined as __________. A) one-half the distance between the nuclei of two atoms B) the distance between the nuclei of two atoms C) one-half the diameter of an atom D) the diameter of an atom

Answer 1

A) one-half the distance between the nuclei of two atoms

Explanation:

Atomic size is quite difficult to estimate due to distribution of electrons in an atom. The distribution of electrons in an atom is never zero. Atoms do not really have an outer boundary.

The atomic radius is therefore used to estimate the size of an atom. It is taken as "half of the inter-nuclear distance (d) between two covalently bonded atoms or a non-metallic element or half of the distance (d) between two nuclei in the solid state of metals".
