Magnesium is Mg. Mn is manganese. QUESTION: Which of the these elements is paired with its correct symbol? A. magnesium, Mn B. potassium, Po C. fluorine, F D. argon, AR Argon is Ar. SCRIPT: Which of the these elements is paired with its correct symbol? Magnesium, … potassium…, fluorine…, or cobalt PAUSE We can immediately eliminate choice D. In the symbol for any element, the first letter… and only the first letter… should be capitalized. CROSS OUT D CLICK The symbol for argon is upper case A, lower case R. Even though R is written small here, it’s still capitalized. CLICK The symbol for magnesium is capital M, lower case g. Capital M, lower case N is the symbol for manganese. So choice A is wrong. CROSS OUT A CLICK The symbol for potassium is capital K. K is the first letter in the Latin name for potassium, which is Kalium. Capital P, lower case O is the symbol for So choice B is wrong. CROSS OUT B. Choice C is correct. The symbol for fluorine is capital F. Magnesium is Mg. Mn is manganese. Potassium is K. Latin name of potassium is Kalium. Po is polonium.
