Brown, H. Eugene LeMay, Bruce E. Figure 2. Periodic Graphics: The Compositions of U. Chapter 2. Students often cannot relate the charges on common monatomic ions to the position of their parent atoms in the periodic table.
Students often do not realize that an ionic compound can consist of nonmetals only, e. Students often confuse the guidelines for naming ionic compounds with those for naming binary molecular compounds. Students routinely underestimate the importance of this chapter. It is critical that students learn the names and formulas of common and polyatomic ions as soon as possible.
They sometimes need to be told that this information will be used throughout their careers as chemists even if that career is only one semester. Remind students that families or groups are the columns in the periodic table; periods are the rows. Emphasize to students that the subscripts in the molecular formula of a substance are always an integral multiple of the subscripts in the empirical formula of that substance.
Greek Philosophers: Can matter be subdivided into fundamental particles? Democritus — BC : All matter can be divided into indivisible atomos. Atoms are neither created nor destroyed. Atoms are the building blocks of matter. Law of constant composition: The relative kinds and numbers of atoms are constant for a given compound.
Law of conservation of mass matter : During a chemical reaction, the total mass before the reaction is equal to the total mass after the reaction, chemistry the central science 14th edition pdf download. Here, the term applies to matter mass.
Later we will apply it to energy Chapter 5. Law of multiple proportions: If two elements, A and B, combine to form more than one compound, then the mass of B combines with the mass of A in a ratio of small whole numbers. By scientists knew that atoms consisted of charged particles. Subatomic particles are those particles that make up the atom. Recall the law of electrostatic attraction: like charges repel, chemistry the central science 14th edition pdf download, and opposite charges attract.
The voltage causes negative particles to move from the negative electrode cathode to the positive electrode anode. The path of the electrons can be altered by the presence of a magnetic field. Consider cathode rays leaving the positive electrode through a small hole. The applied electric field forces the drops upward, chemistry the central science 14th edition pdf download.
Knowing the charge-to-mass ratio of the electron, we can calculate the mass of the electron: 19 1. The radiation is passed between two electrically charged plates and detected. Three spots are observed on the detector: 1. A large deflection toward the positive plate corresponds to radiation that is negatively charged and of low mass. This is called -radiation consists chemistry the central science 14th edition pdf download electrons.
This is called -radiation similar to X-rays. A small deflection toward the negatively charged plate corresponds to high-mass, positively charged radiation.
This is called -radiation positively charged core of a helium atom. The atom consists of positive, negative, and neutral entities protons, electrons and neutrons. Protons and neutrons are located in the nucleus of the atom, which is small. Most of the mass of the atom is due to the nucleus. Electrons are located outside the nucleus.
Most of the volume of the atom is due to electrons. The quantity 1. The angstrom is a convenient non-SI unit of length used to denote atomic dimensions. Masses are so small that we define the atomic mass unit, amu. Thus, isotopes have the same Z but different A. Isotopes have the same number of protons but different numbers of neutrons.
All atoms of a specific element have the same number of protons. The sample is charged as soon as it enters the spectrometer. The charged sample is accelerated using an applied voltage. The ions are then passed into an evacuated tube and through a magnetic field. The magnetic field causes the ions to be deflected by different amounts, depending on their mass. The ions are then detected.
The periodic table is used to organize the elements in a meaningful way. As a consequence of this organization, there are periodic properties associated with the periodic table. Rows in the periodic table are called periods. Columns in the periodic table are called groups. The structural formula gives chemistry the central science 14th edition pdf download connectivity between individual atoms in the molecule. The structural formula may or may not be used to show the three-dimensional shape of the molecule.
If the structural formula does show the shape of the molecule, then either a perspective drawing, a ball-andstick model, or a space-filling model is used. If electrons are added to or removed from a neutral atom, an ion is formed. When an atom or molecule loses electrons, it chemistry the central science 14th edition pdf download positively charged. When an atom or molecule gains electrons, it becomes negatively charged. In general, metal atoms tend to lose electrons, and nonmetal atoms tend to gain electrons.
The number of electrons an atom loses is related to its position on the periodic table. Anions can also be viewed as particles originating from acids, and thus as having negative charges equal to — the number of acidic hydrogen atoms in molecules of those acids e.
NaCl is an example of an ionic compound consisting of positively charged cations and negatively charged anions. Therefore, we cannot use molecular formulas to describe ionic substances. In general, ionic compounds are combinations of metals and nonmetals, whereas molecular compounds are composed of nonmetals only.
Chemical chemistry the central science 14th edition pdf download is the naming of substances. Common names are traditional names for substances e. Systematic names are based on a systematic set of rules. Names and Formulas of Ionic Compounds 1. Cations formed from nonmetals end in -ium.
The one with more oxygen ends in -ate. The exception is NH3. If both elements are in the same group, the lower one is written first. Greek prefixes are used to indicate the number of atoms e. Organic chemistry is the study of carbon-containing compounds. Isomers are compounds with the same molecular formula but different arrangements of atoms.
Carbon atoms often form compounds with long chains of carbon atoms. CCl4 in Chapter 9solubility of organic compounds in water or organic solvents e. John J. This reference includes demonstrations of the concepts of the conservation of mass in chemical reactions, the Law of Multiple Proportions, etc.
Robert L. Mary V. Barrie M. An article describing methods used to isolate important isotopes. Arthur M. Last and Michael J. John H. Jared D. Persinger, Geoffrey C. Hoops, and Michael J. Steven I. News, Vol. Sushama D. Marshall W. Rene E.
