Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium , is soft enough to be cut without much force. Pure tin after solidifying keeps a mirror-like appearance similar to most metals.
Group 3 is the first group of transition metals in the periodic table. This group is closely related to the rare earth elements. Although some controversy exists regarding the composition and placement of this group, it is generally agreed among those who study the matter that this group contains the four elements scandium Sc , yttrium Y , lutetium Lu , and lawrencium Lr. The group is also called the scandium group or scandium family after its lightest member. Due to the effects of the lanthanide contraction , yttrium and lutetium are very similar in properties. Yttrium and lutetium have essentially the chemistry of the heavy lanthanides, but scandium shows several differences due to its small size.
Click a column header, such as Name, to sort the table by that item. SEE Notes at the bottom of the Table. Clarke and H. Washington, Elemental composition of crustal rocks differ between different localities see article. Lanthanoids and Actinoids are numbered as and to separate them in sorting by group. For these elements the weight value shown represents the mass number of the longest-lived isotope of the element.

This page describes and explains the trends in atomic and physical properties of the Period 3 elements from sodium to argon. It covers ionisation energy, atomic radius, electronegativity, electrical conductivity, melting point and boiling point. These topics are covered in various places elsewhere on the site and this page simply brings everything together - with links to the original pages if you need more information about particular points. In Period 3 of the Periodic Table, the 3s and 3p orbitals are filling with electrons.
The periodic table of elements has a total of entries. Elements are arranged in a series of rows periods in order of atomic number so that those with similar properties appear in vertical columns. Elements in the same period have the same number of electron shells; moving across a period so progressing from group to group , elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
The periodic table below is based on the ones used by the different examination boards. The group numbers 1 to 0 the top ones are used in most GCSE courses.
- Сьюзан нахмурилась. - Итак, вы полагаете, что Северная Дакота - реальное лицо. - Боюсь, что. И мы должны его найти. Найти тихо.
Так ты со мной, Сьюзан? - спросил. Сьюзан улыбнулась: - Да, сэр. На сто процентов. - Отлично. А теперь - за работу.
Из пулевого отверстия в виске хлестала кровь - прямо на .
The noble gases Group 18 are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells octets make them extremely nonreactive.
