Your answer should have four significant figures. To find the weighted average mass of lithium (which is equal to the average atomic mass of Li), we simply scale the mass of each isotope by its percentage, expressed as a decimal, and add the weighted masses together: (0.9241×7.016 amu)+ (0.0759×6.015 amu)=6.940 amu.

Which Metals Are Magnetic? | Metal Supermarkets - …

2015/10/27· There are two types of permanent magnets: those from “hard” magnetic materials and those from “soft” magnetic materials. “Hard” magnetic metals tend to stay magnetized over a long period. Common examples are: Alnico alloy, an iron alloy with aluminum, nickel and cobalt. Alnico alloys make strong permanent magnets.

Practice Problem 5. The bone and tooth enamel in your body contain ionic compounds such as calcium phosphate and hydroxyapatite. Predict the formula of calcium phosphate, which contains Ca 2+ and PO 43- ions. Calculate the value of x, if the formula of hydroxyapatite is Ca x (PO 4) 3 (OH).

4.4: Oxidation-Reduction Reactions - Chemistry LibreTexts

2021/4/13· The term oxidation was first used to describe reactions in which metals react with oxygen in air to produce metal oxides. When iron is exposed to air in the presence of water, for example, the iron turns to rust—an iron oxide. When exposed to air, aluminum metal develops a continuous, transparent layer of aluminum oxide on its surface.

Transition Metals - Purdue University

The main group metals tend to form salts (such as NaCl, Mg 3 N 2, and CaS) in which there are just enough negative ions to balance the charge on the positive ions. The transition metals form similar compounds [such as FeCl 3 , HgI 2 , or Cd(OH) 2 ], but they are more likely than main group metals to form complexes, such as the FeCl 4 - , HgI 4 2- , and Cd(OH) 4 2- ions, that have an excess nuer …
