A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Period A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. ... Lead is the Eeyore of metals - slow, dull and heavy. In its Latin form, ...


Lead (/ ˈ l ɛ d /) is a chemical element with symbol Pb (from the Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air.


Lead atoms have 82 electrons and the shell structure is The ground state electronic configuration of neutral lead is [Xe].4f 14.5d 10.6s 2.6p 2 and the term symbol of lead is 3 P 0.. Lead: description Your user agent does not support the HTML5 Audio element.


The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.The structure of the table shows periodic trends.The seven rows of the table, called periods, generally have metals on the left and non-metals on the right.


Lead has been known since ancient times. The origin of the name comes from the Latin word plumbum meaning liquid silver.It is a very soft, highly malleable and ductile, blue-white shiny metal that tarnishes in moist air but is stable in oxygen and water.


To read the periodic table, start at the top left with the elements with the lowest atomic numbers, which tells you how many protons each atom has. Then, as you move right across the chart, make note that the atomic weight, shown at the bottom of the square, also increases.


Interactive periodic table with dynamic layouts showing names, electrons, oxidation, trend visualization, orbitals, isotopes, and compound search. Full descriptions from write-up sources.


Periodic table of the elements: Periodic table of the elements, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.


The periodic table of the elements. The periodic table is an arrangment of the chemical elements ordered by atomic number so that periodic properties of the elements (chemical periodicity) are made clear.


The Chemistry Division's Periodic Table describes the history, properties, resources, uses, isotopes, forms, costs, and other information for each element. ... Lead is obtained chiefly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead minerals.
