Although some people fall into the trap of visualizing atoms and ions as small, hard spheres similar to miniature table-tennis balls or marbles, the quantum mechanical model tells us that their shapes and boundaries are much less definite than those images suggest.

As radius decreases across a period, the electron you are removing is closer to the nucleus and harder. By choosing elements from the periodic table, atoms can be selected for a side by side comparison and analysis. What causes this trend? Examine your graph. What trend in atomic radius occurs down a group on the periodic table?

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity , ionization energy , electron affinity , atomic radii , ionic radius , metallic character , and chemical reactivity. Periodic trends arise from the changes in the atomic structure of the chemical elements within their respective periods horizontal rows and groups in the periodic table. These laws enable the chemical elements to be organized in the periodic table based on their atomic structures and properties. Due to the periodic trends, the unknown properties of any element can be partially known. Several exceptions, however, do exist, such as that of ionization energy in group 3, The electron affinity trend of group 17, the density trend of alkali metals aka group 1 elements and so on. The periodic trends are based on the Periodic Law, which states that if the chemical elements are listed in order of increasing atomic number , many of their properties go through cyclical changes, with elements of similar properties recurring at intervals.


Trends related to placement of elements on the periodic table are often taught using diagrams in a textbook. Students often memorize trends, but to get a true grasp of their meaning and what causes certain patterns is best understood when students create their own models and discuss the patterns with others. Some of the worksheets below are Periodic Trends Worksheet with Answers, use the periodic table, charts, and your knowledge of periodic trends to answer several exam-style questions. Use the information in the given table to create graphs to discover the trends that exist in the periodic table. Learning Outcomes: Know the basic properties of each class of elements. Background: The periodic table is a table that holds all the chemical elements found on Earth.

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine the most electronegative element is assigned a value of 4. Consider a bond between two atoms, A and B.

 Спасибо. Я лишь хотел спросить, есть ли в городе клубы, где собираются молодые люди - панки. - Клубы. Для панков? - переспросил бармен, странно посмотрев на Беккера. - Да. Есть ли в Севилье такое место, где тусуются панки. - No lo se, senor.

Сьюзан вдруг поняла, что стала смеяться гораздо чаще, чем раньше. Казалось, не было на свете ничего, что Дэвид не мог бы обратить в шутку. Это было радостное избавление от вечного напряжения, связанного с ее служебным положением в АНБ. В один из прохладных осенних дней они сидели на стадионе, наблюдая за тем, как футбольная команда Рутгерса громит команду Джорджтауне кого университета. - Я забыла: как называется вид спорта, которым ты увлекаешься? - спросила Сьюзан.  - Цуккини. - Сквош, - чуть не застонал Беккер.

Сначала от Беккера его отделяла лишь одна супружеская пара, и он надеялся, что они куда-нибудь свернут. Но колокольный звон растекался по улочке, призывая людей выйти из своих домов. Появилась вторая пара, с детьми, и шумно приветствовала соседей.

 Но вы же не знали. Стратмор стукнул кулаком по столу. - Я должен был знать.

Его лицо залила мертвенная бледность. Беккер предпринял последнюю попытку: - Мистер Клушар, я хотел бы получить показания этого немца и его спутницы. Вы не скажете, где они могли остановиться.
