What alkali metal element is less reactive than calcium?
it is the lithium metal. it is less reactivated.
Which is less electronegative than silicon?
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.
If the electronegativity difference between elements X and Y is 2.1 the bond between the elements X-Y is?
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.
What is the rule for naming compounds with only two elements?
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.
Which term is given to a substance that can not separate into less complex substance by chemical means?
an element
What element is less electronegative than silicon?
Aluminum is less electronegative than silicon.
What determines the order in which the component elements of binary compounds are written?
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.
What is the oxidation number of hyrdogen?
+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)
Which binary compound combines halogen with another less-electronegative element or radical?
it is called a halide.
Is carbide and tungsten same element?
Both are different. Tungsten in an element whereas a carbide is a compound composed of carbon and a less electronegative element.
Is phosphorus electronegative?
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.
How is the of the second element in a covalent molecule changed?
The ending of the second element is changed to -ide
Is oxide an element or an compound?
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
What alkali metal element is less reactive than calcium?
it is the lithium metal. it is less reactivated.
Which element within a compound is shown first within the compound's name?
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.
What is the name for S2O8?
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.
How do you claculate electronegativity URGENT?
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.
