how does an alloy from differ from a metal? name two alloys.
Answers
Answer:
Pure metals are elements made of all one type of atom
Alloys are mixtures made of more than one element or type of atom.
Explanation:
Pure metals are made of only one type of atom and therefore are elements. The metallic bonding is uniform throughout the metal
Alloys are made of several types of metallic atoms. This makes alloys mixtures. The metallic bonding is not uniform throughout the metal alloy. This makes the alloy stronger and different than pure metals.
An example is steel. Steel is an alloy of iron and carbon and other atoms such as chromium. The carbon makes the steel stronger and more flexible than pure iron. Chromium makes steel more resistant to corrosion than pure iron forming stainless steel.

Answer:
Brass,Bronze
Explanation:
Pure metals consist of a single element. Samples of these metals contain nothing but atoms of a single metallic substance. Alloys contain two or more elements or alloys melted and blended together, so their chemical formulas consist of more than one element. For example, the pure metal iron consists only of iron atoms. Steel, an alloy of iron and carbon, contains mostly iron atoms with isolated atoms of carbon that lend it strength. Adding the metals chromium or molybdenum to the steel produces yet another alloy: stainless steel.
