Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of atomic number, then the elements with similar chemical properties occur at regular intervals or periodic intervals. The elements are arranged in a periodic table in which the arrangement was based on the atomic number of the elements and the elements that have similar chemical properties are positioned in vertical columns.

General, Organic, and Biological Chemistry Seventh Edition
- An atom that has lost three electrons will have a charge of .arrow_forwardThe number of protons in an atom determines the identity of the atom. What does the number and arrangement of the electrons in an atom determine? What does the number of neutrons in an atom determine?arrow_forwardHow many protons and neutrons are contained in the nucleus of each of the following atoms? For an atom of the element, how many electrons are present? a.2963Cu b.3580Br c.1224Mgarrow_forward
- The contributions of J. J. Thomson and Ernest Rutherford led the way to todays understanding of the structure of the atom. What were their contributions?arrow_forwardWhat is the modern view of the structure of the atom?arrow_forwardWhat is meant by anuclear atom? Describe the points of Ruth erford’s model for the nuclear atom and how he tested this model. Based on his experiments, how did Rutherford envision the structure of the atom? How did Rutherford’s model of the atom’s structure differ from Kelvin’s “plum pudding” model?arrow_forward
- Explain the operation of a cathode-ray tube. Describe the deflection of cathode rays by electrically charged plates placed within the cathode-ray tube. What does this imply about cathode rays?arrow_forwardVariations in average atomic mass may be observed for elements obtained from different sources. Lithium provides an example of this. The isotopic composition of lithium from naturally occurring minerals is 7.5% 6Li and 92.5% 7Li, which have masses of 6.01512 amu and 7.01600 amu, respectively. A commercial source of lithium, recycled from a military source, was 3.75% 6Li (and the rest 7Li). Calculate the average atomic mass values for each of these two sources.arrow_forwardHow are protons and neutrons similar? How are they different?arrow_forward
- Advances in technology and science often progress hand-in-hand. What advance in technology was necessary to set the stage for the discovery of the electron?arrow_forward2.42 What is a period in the periodic table? From what does it derive its name?arrow_forwardCarbon A carbon atom has a mass number of 12 and an atomic number of 6. How many neutrons does it have?arrow_forward
