An atom is the smallest particle of any element that retains ✏ Mark the Text the properties of the element. Identify Definitions The particles that make up an atom are called subatomic Highlight the definition of particles. Atoms are composed of three subatomic particles: each word that appears in protons, neutrons, and electrons. ● ✔ bold type. ● ✔ Reading Check Which has a positive elec- tric charge, a proton, a neutron, or an electron? Nuclear charge is the electric charge on the nucleus. This charge is always positive, since the protons have a positive charge and the neutrons are not charged. Atomic number is the number of protons. The nuclear charge or atomic number is given in the top left hand corner of the element box for each element in the periodic table. How does the periodic table provide information about elements? In the periodic table, each element is listed according to its atomic number. Each row is called a period.

Name Date 4.1 Summary continued is called a group or family. Metals are on the left side and in the middle of the table. Non-metals are in the upper right corner. The metalloids form a staircase toward the right side. The block of elements from groups 3 through 12 are the transition metals. Elements in the same chemical group or family have similar chemical properties. For example, group 17 contains very reactive non-metals known as halogens (i.e., fluorine, chlorine, bromine, etc.) Group 18 contains the non-reactive noble gases. How do Bohr diagrams represent atoms? A Bohr diagram shows the arrangement of subatomic particles in atoms and ions. Electrons are organized in “shells”. The first shell holds a maximum of two electrons; the second shell a maximum of eight. When this shell is filled, it is called a stable octet. The outermost shell containing electrons is called the valence shell. The electrons in this shell are called valence electrons. These electrons are involved in chemical bonding. When an atom forms a compound, it acquires a full valence shell of electrons and achieves a stable, low energy state. On the periodic table, elements in Group 1 have 1 electron in their valence shell, elements in Group 2 have 2 (a lone pair), elements in Group 3 have 3, and so on. 19p 20n The Bohr diagram for a potassium atom What are ionic and covalent compounds? There are two basic types of compounds: ionic and covalent. 1. Ionic compounds: When atoms gain or lose electrons, they become electrically charged particles called ions. An ionic compound contains a positive ion (usually a metal) and a negative ion (usually a non-metal). In ionic bonding, one or more electrons transfer from each atom of the metal © 2008 McGraw-Hill Ryerson Limited Section 4.1 Atomic Theory and Bonding • MHR 57 056_080_BCSci10_U2CH04_098461.in57 57 PDF Pass 7/21/08 8:11:50 PM

Name Date 4.1 Summary continued to each atom of the non-metal. The metal atoms lose electrons, forming cations. For example, aluminum forms a 3+ cation as a result of losing three electrons. Some metals are multivalent and can form ions in several ways, depending on the chemical reaction they undergo. For example, iron is multivalent because it can lose two or three electrons to become a Fe2+ or Fe3+ ion. The non- metal atoms gain electrons, forming anions. Chlorine gains one electron and forms a 1- anion. The common ions are sometimes shown in the upper right- hand corner of the element’s box in the periodic table. For a multivalent metal, the most common charge is listed first. 2. Covalent compounds: In covalent bonding, the atoms of a non-metal share electrons with other non-metal atoms. An unpaired electron from each atom will pair together, forming a covalent bond. These two electrons are sometimes called a bonding pair. ؉1 ؊1 Na Cl H F ● ✔ Reading Check What is a Lewis diagram? The ionic compound sodium chloride The covalent compound hydrogen fluoride What is a Lewis diagram? A Lewis diagram illustrates chemical bonding by showing only an atom’s valence electrons and its chemical symbol. Lewis diagrams can be used to represent elements, ions, and compounds. ●✔ ؊ 2+ 2؊ H Cl Mg O hydrogen atom chlorine ion magnesium oxide molecule 58 MHR • Section 4.1 Atomic Theory and Bonding © 2008 McGraw-Hill Ryerson Limited 056_080_BCSci10_U2CH04_098461.in58 58 PDF Pass 7/21/08 8:12:46 PM
