When naming ionic compounds, we always name the cation first with its full scientific name. Then, we name the anion, cutting off the last syllable and adding the suffix -ide . Sodium chloride, for instance, is an ionic compound containing sodium and chlorine. 3. Covalent bonds - 2 nonmetals, share electrons, Ionic bonds - metal and a nonmetal, transfer of electrons 4. Word Equation: Iron metal plus oxygen gas form iron (II) oxide, Skeleton equation: Fe + O 2 → FeO Balanced equation: 2Fe + O 2 → 2FeO 5.

A covalent bond is where two atoms share two electrons. They do this to try to fill their valence shells. Covalent bonds have well defined lengths (~1.0 to 2.5 Å) and bond strengths (~100 kcal/mol) How to: One way to predict whether a bond is ionic or covalent is to look how far apart the two atoms forming the bonds are in the periodic table.

Writing Ionic Formulas –“Short Cut” Fe 2+ O2-Fe 2O2 If you use the “short-cut” method, you must reduce the subscripts to the lowest whole number ratio FeO Reduce This “reduce” rule is for ionic compounds. You do not want to “reduce” for covalent compounds. Metal vs Nonmetal Ions Metal ions are named the same as neutral metal atoms.

2.4.5 Ionic, Covalent, and Metallic Crystals 2.18 Different kinds of bonds in different minerals. As shown in the triangular diagram (Figure 2.18), bonding in most minerals is neither 100% ionic, 100% covalent, nor ionic 100% metallic, but some come close. Most minerals contain combinations of ionic and covalent bonding.

Covalent bonds form when two or more nonmetals combine. For example, both hydrogen and oxygen are nonmetals, and when they combine to make water, they do so by forming covalent bonds. Nonmetal atoms in polyatomic ions are joined by covalent bonds, but the ion as a whole participates in ionic bonding. For example, ammonium chloride has ionic bonds between a polyatomic ion, NH 4+, and Cl − ions, but within the ammonium ion, the nitrogen and hydrogen atoms are connected by covalent bonds: If the difference is small, the bond is covalent. If the difference is large, the bond is ionic. Click again to see term 👆. Tap again to see term 👆. Nice work! You just studied 31 terms! Now up your study game with Learn mode. Try Learn mode.
