What properties of gases are covered in Boyle's law? What are some examples of inert gases? What property of a chemical element makes it unique? What are inert gases called? What is the noble gas notation for tellurium? How many electrons do noble gases have in their outer most level?
Define and give an example of electronegativity. What determines what kind of chemical element an atom is? What determines the chemical properties of an element? How can electronegativity cause a covalent bond to be polar? Which element has the highest electronegativity?
Covalent bonds can be classified in one of two ways; polar covalent and nonpolar covalent. Polar covalent bonds are the result of an unequal sharing of the electrons in a bond. One element pulls the electron pair more aggressively than the other element in a polar bond. They key to ...
Silicon has total 14 electrons in its isolated atom. The first orbit consists of 2 electrons. The second orbit consists of 8 electrons and the third orbit consists of 4 electrons. As there are four electrons in the outer most orbit of a silicon atom, the silicon is a tetravalent element. ...
It is a practice to indicate the valency of an element with variable valency by using the appropriate Roman numeral as a superscript placed next to the symbol of the element. For example, writing PVCl5 indicates that phosphorus has a valency of +5 in phosphorus pentachloride. ...

A skyscraper built on a base of solid rock. Core To remove small plugs of sod from (turf) in order to aerate it. Base A basic or underlying element; infrastructure The nation's industrial base. Core To form or build with a base or innermost part consisting of a different substance from...
One of the great tenets of organic chemistry is that its central element, carbon, can form a maximum of four covalent bonds. Methane, the archetypal organic molecule is essentially a carbon atom at the centre of a tetrahedron of four hydrogen atoms, with each hydrogen bonded to the carbon ...
Ionic compounds are similar to covalent bonds, but differ in terms of how the electrons of the two atoms interact. Ionic compounds a formally defined as a grouping of atoms of more than one element connected through ionic bonds. In a covalent (molecular) bond, the electrons are shared, where...
The one thing I know about electronegativity is that it is the opposite of electropositivity (which is the likelihood of an element to donate electrons, rather than gain electrons.) And the only reason I know about electropositivity, is because I recently read an article on how electropositive...
