What else can I help you with?
What is the most electropositive element?
Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium
Is fluorine electropositive?
No, no, no... Fluorine is the most electronegative of all
Why is the bond between an electropositive and an electronegative atom ionic in natyre?
The bond between an electropositive and an electronegative atom is ionic because the electronegative atom attracts electrons from the electropositive atom, leading to the transfer of electrons. This transfer results in the formation of ions with opposite charges, which are held together by strong electrostatic forces.
Why is the bondbetween an electropositive and electronegative atom ionic in nature?
The bond between an electropositive and electronegative atom is ionic in nature because the electronegative atom attracts the electron(s) from the electropositive atom, leading to the transfer of electron(s) from one atom to the other. This results in the formation of oppositely charged ions that are held together by electrostatic forces.
Why isn't francium the most electropositive element?
Although francium is very electropositive, cesium is typically considered more electropositive. This is because francium is rare and highly radioactive, making it difficult to study and utilize for practical purposes. Additionally, the large size of the francium atom leads to some electron shielding, decreasing its electropositivity compared to smaller atoms like cesium.
Are chemical symbols placed in a certain way in a chemical formula?
more electropositive element first, followed by electronegative elements
What is a butyl?
A butyl is either of four isomeric univalent hydrocarbon radicals, chemical symbols C4H9.
What valencies is vanadium likely to have?
Vanadium has the following valencies: 2, 3, 4 and 5.
How many symbols are there in the Chinese language?
Too many to count. Each character has little symbols that cannot be broken down any farther, called Radicals. Although there are common radicals, there are also uncommon ones, and new combinations to create different words are still being created.
Which halogen is more electropositive?
Flourine is most electropositive as it is smallest and has fewest shells to shield the positive charge of the nucleus.
How many valencies are there in nitrogen?
7
What are the valencies of the elements of the periodic table?
kuru
What is mean by valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
How do you learn symbols and valencies?
You need to learn the symbols for the elements I am afraid. Start using a Periodic table (see the links below).You could also learn the valencies but if you know the periodic table and understand why elements appear where they do, you can work out the likely valencies from the positions of the elements in the table - they are where they are for a reason!You must ask your chemistry teacher to explain this reasoning to you - it should form part of your lessons.This will helpGroup number 1 = Valency 1group number 2 = valency 2group number 3 = valency 3group number 4 = valency 4group number 5 = valency 3group number 6 = valency 2group number 7 = valency 1group number 8 = valency 0 (noble gases, nonreactive)
What do you mean by variable valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
What is the coordination geometry of CoCl2 6H2O?
CoCl2.6H2O has 6 water molecules attached as secondary valencies and 2 chlorine atoms are serving as the primary valencies. The secondary valencies are directional in nature and hence they lead to the geometry of it. The geometry of this compound is Octahedral with cobalt showing a coordination no. of 6.
