Key Question Unit 1. 1)For The Increasing Of Current Funding

2. Using the atom and bond library below, construct the following molecule. It may be

2. Describe the three different types of bonds, providing examples of molecules formed through each type of bond. (3 points) Covalent bond, methane. Ionic bond, table salt. Hydrogen bond, water.

People also benefit from atomic research in the medical field. Many people are aware of the wide use of radiation and radioisotopes in medicine. Nuclear medicine mostly uses radioisotopes which emit gamma rays from within the body. Estimates show that about one out of every three hospital patients benefits in some way from the use of nuclear medicine. Just think, every time you have an X-ray taken you are benefiting from nuclear research. Without X-rays, doctors would have a far greater time trying to set a broken bone if they even knew it was broken! Another common medical procedure that involves atomic research is the Cat-Scan. During this procedure the patient is injected with a radioactive isotope which shows the flow of blood through the

Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct?

- Discovery of X-rays led to other majors and improved diagnostic tools such as CAT scan which will lead to the conception of PETT scan and MRI.

A) They feature carbon atoms which are covalently bonded to hydrogen (Open Learning Initiative, 2015, pg.63).

Moles – an amount of material (atoms, ions or molecules) that contains Avogadro’s number (6.022 x 1023) of particles.

34. The kernel of an atom includes everything in an atom except the atom’s valence electrons.

2. In atomic ions the oxidation number is the charge on the atom (monatomic ion)

Our image of an atom has changed throughout history. The atom is the smallest unit to make all matter. Every solid, liquid and even gas has matter composed of atoms.  Many people have contributed to our understanding of atoms that dates back to as far as Ancient Greece. That goes to show how much work scientists have put in to help us unlock more doors to life.

1. The development of MRI imaging technology is one useful spinoff of basic research into the structure of the atom. Research, however, is expensive. Many people argue that the high cost of research outweighs its potential benefits. Provide one argument for, and one argument against increasing current funding for atomic structure research. Use specific examples from this lesson in your answer to support each position. (6marks)

Multiple forms of the same element that have the same amount of protons but different number of neutrons in their nuclei.

Aqueous solutions of acids have a pH of less than 7." All of these factors help make up the inorganic substances. When writing a chemical formula, you use the Hill system. In this system, you write out carbon atoms first, hydrogen atoms second, and then all other atoms in alphabetical order (if the formula contains no hydrogen or carbon atoms, then you simply sort all the elements alphabetically). A binary compound is a chemical compound that contains two different elements. The opposite would be a polyatomic ion compound which is a chemical compound that consists of more than one atom. the difference between them is binary compounds have two different elements where as polyatomic ion compounds have two or more atoms. One contains compounds (which are already atoms put together) and one contains only atoms. A substances name depends on its compounds and atoms. The chart above names NO2 (NO_2)as nitrogen dioxide. This is its name because it has one nitrogen (nitrogen) and two oxygen (dioxide). Each chemical has a symbol and each compound has a name. This is how we write them

This began the research of the atom's nuclear structure. Rutherford showed the science world that nuclei of light elements could be destroyed by radioactivity. He also learned that fast protons are emitted from the nucleus when radioactivity interacted with the nuclei. Rutherford didn't stop there, he kept going on discovering new things, and was greatly acknowledged for all his hard work. (NNDB, 2014).

How many parents would like to send their children to a school that does not even have the resources to teach them appropriately? There are many schools that do not receive the funding they need in order for students to learn, while other schools have more than enough. Students in the lower funded schools are further behind and less likely to succeed compared to the students from the other schools. Therefore, all public schools should receive equal funding because all children deserve to have the same education and learning environment.
