Write the formula of the compound formed between the iron(III) ion and nitrate ion. What is the chemical formula for silver nitrate? What is the chemical formula for the compound formed between chromium(lll) and the nitrate ion? Is the compound copper(II) chlorate ionic, molecular, or an ...
In order to write a chemical formula, it is important to know the symbol of the elements present in the compound, formula of the radicals and the valency of the elements in that compound. Following points should be kept in mind while writing a chemical formula. Most of the compounds are ...
The primary bonds (>100 kJ/mol) are ionic, covalent, and metallic. The secondary bonds are of the van der Waals, or hydrogen. Ionic bonding occurs between metal atoms and nonmetal atoms. To become stable, the metal atom tends to lose one or more electrons in its outer shell, thus ...
Chemical compound formulas provide a shorthand communication for the structure of molecules and compounds. Reading and writing the chemical formula of compounds requires just a little understanding of the language of chemistry. Definitions of Terms Science depends on precision of language to communicate ef...
210 Chapter 7 MAIN IDEA Binary compounds contain atoms of two elements. Compounds composed of two elements are known as binary compounds. In a binary ionic compound, the total numbers of positive charges and neg- ative charges must be equal. Therefore, the formula for such a compound can ...
