&ATOMIC NUMBER AND MASS NUMBERS After reading this section you will be able to do the following: * Define and determine the atomic number of an atom. * Define and determine the mass number of an atom. What is an atom’s atomic number? The number of protons in the nucleus of an atom determines an element’s atomic number. In other words‚ each element has a unique number that identifies how many protons are in one atom of that element. For example‚ all hydrogen atoms‚ and only hydrogen atoms

The numbers are overwhelming: Over the next 17 years‚ 350 million rural residents (more than the entire U.S. population today) will leave the farm and move to China’s cities. That will bring the Chinese urban population from just under 600 million today to close to 1 billion‚ changing China into a country where more than two-thirds of its people are city dwellers‚ says Jonathan Woetzel‚ a director in McKinsey’s Shanghai office. The change will reverse China’s centuries-old identity as a largely rural

estimated birth and passing years are said to be from 150 B.C. to 350 A.D. Although there is not enough information about his life‚ there is a riddle that estimates how long he lived. The mathematic puzzle is known as ‘Diophantus Riddle’. The riddle states he married while he was 33‚ then he had a son who lived for 42 years and the total years Diophantus lived according to the riddle was a total of 84 years. Through his advancements in mathematical notations and having brought symbolism to algebra‚ Diophantus

Algorithm analysis In computer science‚ the analysis of algorithms is the determination of the number of resources (such as time and storage) necessary to execute them. Most algorithms are designed to work with inputs of arbitrary length. Usually the efficiency or running time of an algorithm is stated as a function relating the input length to the number of steps (time complexity) or storage locations (space complexity). Algorithm analysis is an important part of a broader computational complexity

inheritance. In the comparative method a number of different species are studied and then the results are compared and are related in order to understand the human behavior. Physiology basically focuses on how the brain functions‚ how the nervous system and hormones work and how their functions affect human behavior. The Investigation of inheritances focuses on how the mechanism of inheritance works. This paper will shed light on hunger from a scientific biopsychological perspective. When level of

Graham’s number‚ named after Ronald Graham‚ is a large number that is an upper bound on the solution to a certain problem in Ramsey theory. The number gained a degree of popular attention when Martin Gardner described it in the "Mathematical Games" section of Scientific American in November 1977‚ writing that‚ "In an unpublished proof‚ Graham has recently established ... a bound so vast that it holds the record for the largest number ever used in a serious mathematical proof."
