For example, valency of group 2 elements is 2 as they are capable of donating 2 electrons.Answer and Explanation: Valency basically specifies the combining capacity of a particular element when it becomes part of a molecule or compound. Generally, an element's...Become a member and unlock a...
The term valency indicates the number of electrons required to be lost or gained to complete the octet in the valence shell. When an atom forms an ion in an ionic compound, the valency of the ion in that compound then refers to the charge on that ion....
Barium chloride solution is mixed with copper sulphate solution and a white precipitate is observed. View Solution An element Z forms an oxide ZO_(3) . (a) What is the valency of element Z ? (b) What will be the formula of fluoride of Z? View Solution An element Z has a valency of...
Step 3: Identify the Valency- For aluminium, it has 3 electrons in its outermost shell (3s² 3p¹). To achieve a stable configuration (noble gas configuration), aluminium will lose 3 electrons. Thus, the valency of aluminium is 3.- For oxygen, it has 6 electrons in its outermost she...

A lot of progress has been made these last years about the understanding of colossal magnetoresistance (CMR) properties of manganites with the perovskite structure. The role of the interpolated cation (size, mismatch effect) is now well established, whereas the mixed valency of manganese Mn(III)...
What is the valence of tellurium? What is the valence of iodine? What are valance electrons? How do they relate to the periodic table? How many valence electrons are there in chlorine and what is its valency? In which orbital will an electron add to the element chlorine to form Cl-? Wh...
What is the chemistry of iron?Answer and Explanation:In simple chemistry terms, iron is a metal identified by the symbol Fe on the peridodic table of elements and has an atomic number of 26. If there is anything else a bit more specific about iron that you need help with please let us...
The valencies of two elements A and B are given below : ElementValencyA1+B2+ (i) What is formula of sulphate of A ? (ii) What is the formula of nitrate of B ? View Solution The unit cell of a compound made up of the three elements X, Y and Z is given below. The for...
The words valence and valency have two related meanings in chemistry. Valence describes how easily anatomorradicalcan combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. Valence is denoted ...
