1 hemistry Judy van der Velden. reative ommons licence. onic Bonding Practice Grade 10 cience onic ompounds onic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds the electrostatic force between positively charged cations and negatively charged anions. onic compounds have high melting and boiling points, and they are hard and very brittle. They are also called salts. nside: Forming ons Forming onic ompounds ompound rosswords omplete Bohr-Rutherford diagrams for the first 20 elements, & discover the pattern of ionic charges. Practice naming and writing formulæ for combinations of metals, nonmetals, & polyatomic ions. Practice writing the names and formulas of ionic compounds. Page 2 Page 4 onic Bonding Practice Page 10

2 hemistry nstructions omplete Bohr-Rutherford diagrams of the first 20 elements, drawing the electrons as open circles: 〇. The electrons in the inner shells are strongly bound to the nucleus. The ion will retain these. olour them black. Bohr-Rutherford diagrams The electrons in the outer shell may be lost. f the shell is less than half full the ion will lose these electrons. olour them red. f the outer electrons are not lost, colour them blue. H Li Be B a Mg l K a onic Bonding Practice 2

3 f the outer shell is more than half full it will gain electrons to make it full. olour these gained electrons green. When an atom loses electrons, it has a positive charge equal to the number of lose electrons. When it gains electrons, it has a negative charge equal to the number of gained electrons. Write these charges beside the Bohr-Rutherford diagram. hemistry otice the pattern the charges make. ompare the charges you determined to the charges actual charges on a periodic table. re there any differences? Why might this be? He O F e i P l r 2011 Robert Prior 3
