In what way is zinc similar to cadmium which is located just below it on the periodic table?
The two metals both have two electrons in their outer or valence shell. That gives them (predominantly) a +2 electronegativity. This is probably the most fundamental similarity between zinc and cadmium. The two elements are in Group 12 of the periodic table, and elements in the same group gnerally share some chemical tendencies. That's why they're in the same group, which is an appointment (a placement) based on electron structure.
How do you determine if a bond is polar covalent?
Given below is the difference in electronegativity of any two elements:0.0-0.4 = nonpolar covalent bond0.4-1.7 = polar covalent bond>1.7 = ionic bondFor ex. Sodium and Chlorine (Na and Cl)Sodium's electronegativity = 0.93Chlorine's electronegativity = 3.16So, 3.16-0.93 = 2.23 which means NaCl bond is an ionic bondAnswer:When differentiating between covalent (molecular) or ionic, the type of elements in the compound decides which it is. Covalent bonds are between non-metals only. Ionic bonds are between a metal and a non-metal. Covalent bonds can either be polar or non-polar. You could determine this with the known electronegativities of the elements. First you have to represent the molecule by any means necessary (Lewis Dot Structure, lines, etc). This isn't nesessary for a compound with two atoms. Once drawn, you will know which atoms are bonded to the other atoms in the molecule. Then you look at the electronegativities for each element in one bond. If one atom's element has a higher electronegativity value than the other, then the bond is polar. If they are the same, then the bond is non-polar.The reason a bond would be polar is because one atom has a higher electronegativity value, which means that the element has more attraction to electrons than the other. If it is attracting electrons more than the other, then the electrons are spending more time one one side. The disparity of electron distribution causes one side to be slightly negative (δ-) and the other to be slightly positive (δ+).
Which bond has the greatest ionic charcter?
Based on the maximum possible difference in electronegativity, this should be the bond in cesium fluoride.

Arrange the following elements in order of increasing electronegativity N Na Ni K P?
The electronegativity from least to highest : Ba, Be, Bi, B, Br The electronegativity of an element is a measurement of how its atoms attract electrons. This is based on the atomic weight (width of the atomic nucleus) and the distance of its valence electrons from the nucleus. As displayed on the Periodic Table, elements generally increase in electronegativity as you move across (left to right), and decrease as you go down the table. (Only aluminum does not follow this in this set of elements.) (see related link)
What is a bond based on electronegativity?
Hydrogen Bond
How do astronomers identify elements of the stars?
Elements are identified based on their absorption spectra. Every element absorbs a unique set of frequencies when light passes through it. Scientists can determine which elements are present based on which portions of the star's light are absorbed.
A bond based only on electronegativity?
hydrogen bond
What is A bond based only on electronegativity is a?
Hydrogen bond.
What is the relation between Allred-Rochow's electronegativity and Pauling's electronegativity?
Rochow electronegativity is based on the effective nuclear charge of an atom and by extension the attraction a valence electron feels to the nucleus. Pauling electronegativity is based on bonding energies and states that the heteroatomic bond A-B's dissociation energy should be an average of the homoatomic bond A-A and B-B's dissociation energies. Any additional energy differences will be a result of electronegativity. Aside** Muliken electronegativity is an average of the ionization energy and electron affinity of a gas phase atom. All 3 electronegativities increase going up and to the right on the periodic table.
What names the elements that combine to form a compound?
The chemical name of the compound is often based on the names of the elements that are part of it. However, for many simple organic compounds it is not possible to determine the component elements.
Would C and H form a polar covalent bond based on their electronegativity?
Hydrogen electronegativity = 2.2Carbon electronegativity = 2.552.55/2.2= 1.2 variance===================No, not enough variance as about 1.4 is needed.
What is the difference between monochromic and polychromic cultures?
Polychromic cultures determine when it is time to change from one activity to the next based on how they feel. Monochromic cultures determine when it is time to change activities based on clock time.
Where can I research fellowes shredders?
Only you can determine if you will indeed need to get a fellowes shredder and the price is going to vary based upon what elements you want and the brand you want to buy.
