Some elements have different physical properties depending on their chemical makeup as some elements can come in different chemical forms. Below are some elements and compounds as well as their physical properties. Iron. Known as the element Fe, iron has a melting point of 2,800 degrees Fahrenheit.
- Understand basic math and biology, as well as advanced topics like Organic Chemistry and Statistics. Whether you're studying sociology, differential equations or French II, these free CliffsNotes articles can help you when doing your homework, writing papers, or taking tests.
- The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. The ...
Sep 27, 2008 · Because of their similar electronic configuration. They have 1 valence electrons and thus all belong to group 1 alkali metal. The have the same no. of valence electron each and thus have similar chemical properties.
- The chemical elements sorted by name in an alphabetical order. You can click on the column header to sort the table by that column. Click on an element symbol to get detailed facts about the element.
A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound. Mixtures cannot be represented by chemical formulas. Types: A huge, virtually limitless, number of chemical compounds can be created.
- Jan 24, 2005 · All the rest have 31 Except February my dear son. It has 28 and that is fine But in Leap Year it has 29. You'd probably prefer your doctor to know the difference between cyanate and cyanide: Cyanate "I ate" and Cyanide "I died." Cyanide is a little fatal. Remember this one? In 1492, Columbus sailed the ocean blue.
This should be done cautiously for patients whose exposure has resulted in frostbite. Chemical burns which result from chlorine exposure should be treated as thermal burns. Inhalational chlorine poisoning is treated with supportive care and can include administration of humidified oxygen, bronchodilators and airway management.

A short history of the atom ( bozemanbiology, 9 min) is a very well done summary of how atomic theory came about. Elements and atoms (Khan, 13 min) Not one of their best, but still ...
managers in the writing of elements and standards as they prepare performance plans. This material explains how to develop good performance elements and measurable standards. This document contains several job aids, including some examples of generic results-oriented elements and measurable standards.
- Groups of elements in the periodic table have similar chemical properties based upon the atoms': a. number of protons b. number of electrons c. number of valence electrons d. atomic mass View Answer
Elements in the same group (column) have similar properties. The properties change gradually along periods (rows) in the table—elements on the left are metals, elements on the right are nonmetals. As you move across periods, the atomic number increases.
