PENGELOMPOKAN MATERIAL Dalam dunia teknik bahan dikelompokan sesuai dengan JENIS PENGGUNAAN SIFAT / PROPERTIS CONTOH : • Aluminium ,kuningan merupakan logam bukan besi • Mold cavity biasanya terbuat dari baja perkakas/toolsteel • Baja tahan karat , baja magnetis sifat. LOGAM / METAL Logam dan paduannya biasanya dibagi kedalam dua golongan : 1. Logam ferro (ferrous metals) dan paduannya, yang mengandung sejumlah besar besi seperti pada baja dan besi cor. 2. Logam non ferro (nonferrous metals) dan paduannya, yang tidak mengandung basi atau hanya mengandung sedikit saja besi, contoh : Al. Cu, Zn, Ti, Ni. Komponen yang Peralatan dapur dari terbuat dari ...
Bonding • Bond Energy – Energy required to break a chemical bond • Atoms bond in a way that achieves the lowest possible energy for the system • Bond length – distance between the nuclei of two bonded atoms –Shorter bond length = stronger bond = higher bond energy!! Ionic Bonding • Electrons are transferred • Metals react with nonmetals • Ions paired together have lower energy (greater stability) than separated ions • Ionic compounds conduct electricity in a molten state Coulomb’s Law • Shows energy of interaction between a pair of ions • E = Energy, r ...

I. Properties of Ionic Compounds A. high melting & boiling points (above 300°C) B. most are crystalline solids at room temperature C. tend to be soluble (dissolve) in water D. can conduct electricity in a molten state or in solution E. crystallize as sharply defined particles F. generally form between metals (cations) & non-metals (anions) II. Ionic Bonds Why do atoms bond? To be more stable (like noble gases). A. due to transfer of valence electrons B. oppositely charged ions (cation, anion) are attracted to each other C. monatomic ions = single atoms with a + or ...
