Many references give table of atomic radii. Sometimes in text books and other sources, the rather vague term "atomic radius" is not defined and in such cases it is therefore not clear what the values actually mean. The values given here for atomic radius are calculated values using methods ...
clear as the order of the oxygen-oxygen bond is double. In this case, and indeed for most of the periodic table, it is necessary to infer the covalent radius from molecules containing O-O single bonds or from molecules containing a C-X bond in which the covalent radius of X is known....
.The atomic radius is the distance between the nucleus and the outermostelectron ofan atom. 原子半径是指原子核与最外层电子之间的距离 Atomic radii of period 3 elements. .You can see a clear trend across the period which also repeated in period 2. The graph shows a decrease in atomic radii ...
the electrons all exist at roughly the same distance from the nucleus. More protons, however, are added. This creates a greater positive charge at the nucleus, resulting in a greater inward pull on electrons. Hence, the atomic radius, or the distance from the nucleus...
level, the atomic radius grows as it moves down the group. Because adding an electron shell pulls the valence electrons further away from the nucleus, electronegativity falls as you move down a group. Thus in order to understand the trends and properties groups and period are of great ...
The atomic radius is decreasing when going down a group in the periodic table. Is the statement true or false? Nuclear fission occurs when an atomic nucleus splits into two or more smaller and less massive atomic nuclei. Is this statement true or false? Explain. ...

effect is (nearly) constant. However across the period the nuclear charge is increasing and this leads to the increase of effective nuclear charge. Since the outermost shell electrons are experiencing an increasing effective nuclear charge across the period the atomic radius is ...

Explain why as you go across Period 3, the atomic radius decreases. Explain why elements that are in the same group of the Periodic Table tend to show similar chemical behavior. Consider the elements: He, Ne, and Ar. Can you come up with a reason why they are in the same grou...
