Question

Write the formulae and the valencies of the following radicals copper (i) oxide and iron(iii)oxide

Answer 1

Answer•••••

ANSWER:

Two elements having variable valency and compounds formed by them are as follows:

(i) Copper (Cu):

Cuprous oxide [Copper(I)oxide] − Cu2O

Cupric oxide [Copper(II)oxide] − CuO

(ii) Iron (Fe):

Ferrous oxide [Iron(II)oxide] − FeO

Ferric oxide [Iron(III)oxide] − Fe2O3

Step-by-step Explanation:-)

Compound radical is a group of atoms of different elements that behave as an intact unit during a chemical reaction. Atoms in a compound radical do not break apart revealing the individual atoms but remain together forming an intact group of atoms having a valency. This unit behaves just like an atom or a molecule during a reaction...
