Biology: Chemistry in Biology: 02: Elements - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: What is an element? Elements are pure substances that are made up of only one type of atom such as hydrogen, carbon, or mercury. So, what makes one element different from another? Well, it's the number of protons in a single atom of an element. This is called the element's atomic number. For example, hydrogen has one proton in its nucleus, so its atomic number is one. Carbon has six protons, so its atomic number is six. And mercury's atomic number is 80 because it has 80 protons in its nucleus. Since the nucleus contains almost the entire mass of an atom, the number of particles it contains has a big effect on the atom's mass. Each positively charged proton has a mass unit of one, and each neutral neutron also has a mass unit of one. The total number of protons and neutrons in the nucleus of an atom is called the mass number. In this example, the mass number of a hydrogen atom is one. Hydrogen is the only element that usually doesn't have any neutrons. The mass number of this carbon atom with six protons and six neutrons is 12. And the mass number of this mercury atom with 80 protons and 121 neutrons is 201. Needless to say, mercury is a match heavier element than hydrogen or carbon. Even though every atom of the same element always has the same number of protons, sometimes an element has atoms with different numbers of neutrons. Ordinary hydrogen has no neutrons, but there's a version of hydrogen with one neutron and another version with two neutrons. Atoms of the same element with different numbers of neutrons are called isotopes. The three isotopes you see here are all still hydrogen because they all have only one proton. Since neutrons have about the same mass as protons, isotopes of the same element have different mass numbers. In fact, an element's isotopes are often identified by their mass numbers. To sum up, an element is a pure substance made of atoms that always have the same number of protons. This means atoms with different numbers of protons are different elements. The number of protons in one atom of an element is called the atomic number. The number of protons plus neutrons in one atom is called the mass number. Isotopes are atoms of the same element with different numbers of neutrons. [music]

What attorneys say about MLA and The Doe Report:
"I thought you might want to know that after we sent a copy of your illustration to the defendants, with a copy to the insurance company, they increased their offer by an additional million dollars and the case was settled for $1,900,000.00.

I appreciate your help!"

"[I] have come to rely upon the Doe Report and your great staff of illustrators for all my medical malpractice cases. … Please know that I enthusiastically recommend you to all my colleagues.

"[Your staff] was extremely efficient, cooperative and gracious and [their] efforts produced a demonstrative exhibit that we used effectively throughout our trial. The jury verdict of $3,165,000.00 was, in no small measure, due to the impact of the demonstrative evidence. You may be sure that we will call again."
