An atom is the very smallest particle that still the elements properties. All the atoms of an element are alike. They are also different from the atoms of all other elements. For example, atoms of gold are always the same. It does not matter if they are found in a gold nugget or a gold ring. All gold atoms have the same structure and properties. For example, all gold atoms contain 79 protons. One of golds unique properties is that it is a great conductor of electricity. Gold is a better conductor of electricity than copper. Gold is more rare and expensive than copper. Copper is used in house wiring. Gold is far too expensive.

Why are atoms in one element different from those in another element?

It's just this hard when I try to answer the question: Why do older Oklahomans need lawyers? The answers are important enough that they will be a discussion topic of this year's Senior Day at 9 a.m. March 25 in the House Chamber at the Capitol. The following is a preview of some of the answers for review: We can all agree that older Oklahomans need medical care. But even the best care is worthless if an older patient can't drive to the doctor for ongoing treatment because his or her car has been wrongfully seized in a debt dispute. Therefore, lawyers are part of the prescription for regular medical care for many of the 600,000 Oklahomans age 60 and older. Another example: if a doctor treats an elderly patient for a lung ailment, the doctor's treatment will be undone and he will see the patient again and again, if the patient is sent home to an unheated apartment. Lawyers know how to make landlords heat apartments so the medical treatment can stick. (By the way, a May 16, 2001, article in The New York Times reports on a program at Boston Medical Center providing a walk-in legal clinic in the hospital to help fight their patients' legal and administrative battles.) We also can agree that older Oklahomans - like all citizens - have rights to control their health care until they become incapacitated or these rights are transferred to another by legal document or process. "Old" is not a legal classification that results in automatic loss of these rights. Moreover, having an old parent does not automatically confer on children the right to make the parents' health care choices. It follows that an important role lawyers provide for aging Oklahomans is not only to create rights - transferring documents such as durable powers of attorney and guardianship orders, but also to monitor their use. In family situations, for example, lawyers must ensure that powers of attorney and guardianships are used to serve only the person transferring or losing rights. They are not to be used to help a family "manage" their mother or help a doctor or nursing home get permission for a pill or procedure they feel is in the best interest of a patient. Good news: Oklahoma now has a Public Guardianship Program, albeit unfunded, that will supply lawyers to perform this rights-monitoring process Oklahoma grandparents should be able to enjoy their grandchildren, not raise them. But owing to the social problems of divorce and drug use, grandparents are increasingly being called on to raise their grandchildren because of missing parents. Adding to the physical, emotional and financial burden they take on, grandparents face legal problems. All the decisions parents made without a second thought now require evidence of legal authority when made by grandparents.

Earths magnetic field helps protect Earth and its organisms. It protects us from harmful particles given off by the sun. Most of the particles are attracted to the north and south magnetic poles. This is where Earths magnetic field is strongest. This is also where relatively few organisms live. Another benefit of Earths magnetic field is its use for navigation. People use compasses to detect Earths magnetic north pole. Knowing this helps them tell direction. Many animals have natural 'compasses' that work just as well. Birds like the garden warbler in Figure 1.36 use Earths magnetic field. They use it to guide their annual migrations. Recent research suggests that warblers and other migrating birds have structures in their eyes. These structures let them see Earths magnetic field as a visual pattern.
What do animals have naturally that people do not?
