fluorine is most electronegative
and cesium is least electronegative
it is the lithium metal. it is less reactivated.
There are many elements less electronegative than silcon. Look at the periodic table, and pretty much everything (with a few exceptions) to the left of, and below silicon will be less electronegative.
The bond between elements X and Y would be considered as polar covalent since the electronegativity difference is 2.1. In a polar covalent bond, the shared electrons are drawn more towards the more electronegative element, resulting in a partial positive charge on the less electronegative element and a partial negative charge on the more electronegative element.
The rule is that the metallic (or the less electronegative) element goes first, and the non-metallic (or more electronegative) element goes second. And the second element has an alteration in its name to indicate the formation of a compound. For example, sodium + chlorine = sodium chloride.
an element
Aluminum is less electronegative than silicon.
The normal convention is to write the part of the molecule that is less electronegative first then the part that is more electronegative. This has the effect of writing the cation then the anion. For instance, carbon dioxide is written as CO2. Why not write it as O2C and call it dioxygen monocarbide? Once again, we write the less electronegative element first which is C in the example. That is the way to deal with all of the binary molecular compounds.
+1 in most of its compounds (when attached to more electronegative element) -1 in the case of hydrides and hydrocarbons (or when attached to less electronegative element)
it is called a halide.
Both are different. Tungsten in an element whereas a carbide is a compound composed of carbon and a less electronegative element.
Yes, phosphorus is electronegative. It is a nonmetal element located in the nitrogen group of the periodic table. However, phosphorus is less electronegative than elements like oxygen and fluorine.
The ending of the second element is changed to -ide
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
it is the lithium metal. it is less reactivated.
In a compound name, the element that appears first is usually the one that is the least electronegative or has the lower oxidation state. This element is named first, followed by the second element with an -ide suffix. For example, in "sodium chloride," sodium is listed first because it is less electronegative than chlorine.
This is a binary covalent compound, so name the less electronegative element first with the greek prefix. The less electronegative element is sulfur and there are two atoms so the first part is disulfur. Next, name the more electronegative element with the greek prefix indicating the number of atoms. This is tetraoxide. So, S2O4 is disulfur tetraoxide.
You don't calculate electonegativity you look it up in a data book. Fluorine is the most electronegative element and given a value of 4 units. all other elements have values less than that but more than zero.
