What True about balancing chemical equations?
chemical equation is defined as the short-hand representation of a true chemical reaction with the help of symbols and formula. All the atoms and their valencies sjould be balanced on both the sides.
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
Does iron react with tin?
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
How do the periodic properties of the d-block elements compare with those of the main group elements?
The main group elements have fixed valencies but members of the d block have multiple valencies.
Is fluorine electropositive?
No, no, no... Fluorine is the most electronegative of all
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.
How many valencies are there in nitrogen?

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.
What are the valencies of the elements of the periodic table?

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?
