Because living and no living things are made of matter, chemistry affects all aspects of life and most natural events. 2.Name the five traditional areas into which chemistry can be divided? Five traditional areas of study are organic chemistry inorganic chemistry biochemistry analytical chemistry and physical chemistry. 3.Describe the relationship between pure chemistry and applied chemistry? pure research can lead directly to an application but an application can exist research is done to explain how it works. 4.what are two general steps in successful problem solving? The two steps to solve a successful problem is to analyze and calculate. 5. Name to categories used to classify properties of matter? Properties used to describe matter can be classified as extensive or intensive 6. Name three states of matter? Three states of matter are solid liquid and gas. 7.How are mixtures classified? Based on the distribution of their components mixtures an be classified as heterogeneous mixtures or as homogeneous. 8. How did Democritus characterize atoms? Democritus believed atoms were invisible and indestructible. 9. What are three types of subatomic particles? Three kinds of subatomic particles are electrons protons and neutrons. 10. What was the basic new proposal in the Bohr model of the atom? Bohr proposed that an electron is found only specific circular paths or orbits around the nucleus. 11. How are wavelength and frequency of light related? Wavelength and frequency are related by its proportional to each other. 12.Describe the cause of atomic emission spectrum of an element? When atoms absorb energy electrons move in to higher levels. These electrons then loose energy emitting light when return to lower energy levels. 13.what information can be included in a periodic table? The periodic table displays the symbols and names of the elements along with information about the structure of their atoms. How can you determine the number of valence electrons in an atom of a represtative element? To find the number of valence electrons in an atom of representative element simply look at its group number. 15. How can you describe the electrical charge of ionic compound? Although they are compose of ions ionic compounds are electrically neutral. What information does a molecular formula provide? A molecular formula shows how many atoms of each element a molecule contains. 17. What electron configurations do atoms usually achieve by sharing electrons form covalent bond? In covalent bonds electron sharing usually occurs so that atoms attain the electron configurations of noble gases. 18. How are atomic and molecular orbitals releated? Just an atomic orbitals belongs to a particular atom a molecular orbital belongs to a molecule as a whole. 19.what is a vsepr theory? A vsepr theory is a repluson between electron pairs and adjust electron pairs. What happens when polar molecules are between oppositely charged metal plates? When polar molecules are placed between oppositely charged plates they tend to become oriented with respect to the positive and negative plates. Explain how the charges of group A metal and nonmetal ions are related to their positions in the periodic table? When the metals in groups 1a 2a and 3a lose electronics they form cations with positive charges equal to their group number. What are the usual endings for the names of polyatomic ions? The names of most polyatomic anions end in ite, ate. Describe how to determine the names of binary ionic compounds? To name any binary ionic compound place the cation name first followed by the anion name. What two laws describe how chemical compounds form? The law of definite proportions and the law of multiple proportions. Describe how to convert between the mass and the number of moles of a substance? Use the molar mass of an element or compound to convert between the mass of a substance and the moles of a substance.
