Review Class for Naming Compounds

This review focuses on the identification and naming of chemical compounds, emphasizing the distinction between ionic and molecular compounds. Through collaborative activities involving newly introduced classmates, participants will use reference tables and systematic naming to accurately name and formulate compounds. Key discussions will include the HONClBrIF elements, the phosphorous-chlorine compounds, and the validity of various chemical formulas. The review aims to solidify foundational chemistry concepts applicable in various educational settings.

Presentation Transcript

  1. Review Class for Naming Compounds say your name Sit with some new people, and say, “hello, my name is __________, let’s work together, okay?” Paper, pen, reference tables ONLY. Clear desks now.

  2. For each slide there are 2 compounds, tell if each is Ionic or Molecular Write the name or formula for each

  3. 13

  4. What are the HONClBrIF twins? Write the formulas for 2 acids and for 2 bases.

  5. HONClBrIF reminds you of the 7 diatomic elements, hydrogen, oxygen, nitrogen, chlorine, bromine, iodine and fluorine, all have H2 or Br2type formulas Write the formulas for 2 acids and for 2 bases. Tables K + L

  6. What are all the phosphorous – chlorine compounds?

  7. What are all the phosphorous – chlorine compounds? PCl -3 -1 +3 +1 +5 +5 +7 PCl3 phosphorous trichloride PCl5 phosphorous pentachloride PCl7 phosphorous heptachloride PCl3 again PCl5 again In our class there are only 3 phosphorous – chlorine compounds.

  8. Which are correct or wrong? If wrong, why? • Chromium (IV) sulfide • Zinc (II) oxide • Carbon pentoxide • Argon fluoride • Hydrogen monochloride • Tin (IV) fluoride • Mercury (II) bromide • Niobium (II) iodide • Bromine lithide • MgBr3

  9. Which are correct or wrong? If wrong, why? • Chromium (IV) sulfide • Zinc (II) oxide • Carbon pentoxide • Argon fluoride • Hydrogen monochloride • Tin (IV) fluoride • Mercury (II) bromide • Niobium (II) iodide • Bromine lithide • MgBr3 X Cr does +2, +3, +6 ions X Zn NO roman numeral X carbon makes CO,CO2 X argon doen’t react ever YES, it’s hydrochloric acid YES, SnF4 -intoothpasteYES, Hg makes a +2 ion X, Nb only does +3 & +5 X, metal first always! X, Mg+2 + Br-1 = MgBr2
