Pure metals consist of only one type of atom. For example, chromium is on the periodic table of elements, meaning it's a pure metal. An alloy, by contrast, is a mixture of different atoms melded together.
Pure metals are those metals that have not been alloyed with other metallic elements; commercially pure metals are 99% pure minimum.
A pure metal element melts at one temperature (the melting point), while an alloy begins melting at a certain temperature called the solidus and finally completes the transformation to the molten state at a higher temperature called the liquidus.
Pure metals have atoms only of that element — for instance, all iron or gold. These pure metals usually undergo processes to remove impurities of other materials. Alloys have atomic components of multiple elements. Therefore, they have a chemical structure different from pure metals.
What are the properties of a pure metal?Ductile- can be drawn into fine wire.Malleable- can be beaten into thin sheets without cracking.Lustrous- becomes shiny when polished.High density.High melting and boiling points.Good conductor of heat and electricity.
In a pure metal, the force needed to make the layers slide over each other is small. This explains why many pure metals are soft. In an alloy, there are atoms of different sizes. The smaller or bigger atoms distort the layers of atoms in the pure metal.
It has metallic bonds and consists of positive ions. Some common metals are iron, gold, platinum, copper and silver. Steel, on the contrary, is an alloy of iron with differing carbon content, ranging from 0.5 percent to 1.5 percent. In terms of purity, metal is a pure element whereas steel is impure.
The different sizes of atoms in an alloy make their arrangement less regular than a pure metal. This makes the bonds between the atoms weaker, and lowers the melting point. Alloys that melt easily, such as SOLDER, have important uses.
By definition, 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.

Around 95 of the 118 elements in the periodic table are metals (or are likely to be such).
The paralegal, in turn, is able to research and draft most legal documents ( though usually only under the supervision of an attorney), and often assists with the day-to-day operations of a law firm, like scheduling hearings, interacting with clients, and keeping case files and evidence in order. Paralegals cannot give legal advice ...
The biggest distinctions between attorneys and paralegals are education and licensing. To be an attorney, one must attend and graduate from an American Bar Association (ABA) accredited law school (in most cases obtaining a juris doctorate degree); undergo a rigorous background screening by the state in which he or she intends to practice; and take and pass a grueling licensing test called the bar exam designed to determine if the attorney is minimally competent in the major areas of practice in that jurisdiction. Once all of these requirements are met, the individual is sworn in as an attorney and must pay annual fees to maintain a license, participate in ongoing legal education requirements, abide by very strict ethical standards, and in some states must perform a certain amount of charity work. An attorney can represent clients in legal proceedings, give legal advice, and independently perform any activity associated with the practice of law.
Paralegal firms typically render certain legal services at a much lower price than actual law firms, but their services are usually limited to filling out preexisting forms with information provided by the client.
A lawyer is one who has studied the law, just as an historian is anyone who studies history or a geographer is one who studies geography. An attorney, on the other hand, is short for attorney-at-law, ...
hold a professional degree called a juris doctorate (or J.D.) degree, but are not either medical doctors or holders of academic doctorates (like a PhD), they are also not allowed to refer to themselves as “Doctor.”.
These organizations are run by paralegals and usually have no attorneys on staff or, in some jurisdictions, may have an attorney available to oversee things but who takes a very minimal role in the daily operations.
A paralegal is an employee who works for the government, a lawyer, a corporation or a company performing legal work that a lawyer supervises. Their tasks can vary and can depend on what jurisdiction they are working in. Although they are supervised by lawyers, paralegals should still have a thorough understanding of the law.
Lawyers depend on paralegals to relay vital information, so they should communicate well . Paralegals may need to give lawyers client messages, inform lawyers of their latest research or discuss the organization’s calendar with them. That means paralegals should understand the importance of constant communication.
Paralegals frequently use computers to perform legal research and get help with litigation. They will prepare documents for the lawyer on the computer, such as court summaries or witness statements.
There are a variety of professions that are similar to a legal assistant or paralegal, including: Administrative Assistant. Court Reporter. Court Clerk.
A paralegal’s duties may include: Many paralegals obtain a bachelor’s degree in a related subject and earn an associate degree in paralegal studies. They can also complete a paralegal education program through the American Bar Association to get a paralegal studies certificate.
The paralegal profession is somewhat new, and many older lawyers have trouble working with non-lawyers in their field. Lawyers have professional training, and the way they think is essentially analytical.
While lawyers are responsible for the creative thinking behind court cases, their legal assistants are responsible for preparation, logistics, obtaining affidavits and other forms required for court cases, as well as general duties in a law office.
