Explain atomic radius trend
WebAboutTranscript. Atomic and ionic radii are found by measuring the distances between atoms and ions in chemical compounds. On the periodic table, atomic radius generally decreases as you move from left to right across a period (due to increasing nuclear charge) and increases as you move down a group (due to the increasing number of electron ...

WebThe atomic radius trend describes how the atomic radius changes as you move across the periodic table of the elements. In general, the atomic radius of an element tends to increase as you move down an element … WebDec 7, 2024 · The atomic radius increases down a group because as you move down, each group gains a shell, therefore the atomic radius increases as the atom gets larger. note- as you move across a period, there are no shells being added, for elements in the same period all have the same number of shells. Top. Akshat Katoch 2K.
WebIf the atom has a smaller atomic radius, it means the electrons are being pulled close to its nucleus much more (generally) Because of this, Flourine for example would be an electron "hog"-- it is the most electronegative element on the periodic table; and will gladly take away and hold onto an electron. WebExplaining the trend. The trend is explained in exactly the same way as the trend in atomic radii. As you go across the period, the bonding electrons are always in the same level - the 3-level. They are always being screened by the same inner electrons. All that differs is the number of protons in the nucleus.
