Answer to Question #153181 in General Chemistry for Lynne Adams

Question

A scientist thinks he found a new metal, so he published a paper about this metal. About 1 week after the scientist published the paper, you noticed a problem with the paper the scientist wrote. You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered. Using the techniques from Chemistry, you ran a Flame Test with a piece of the metal (the metal is safe to use) that you had shipped to you. You found the metal turned the flame yellow. What metal did you have in your possession?

*Barium

*Calcium

*Strontium

*Copper

*Sodium

Answer 1

Answer: Sodium gives yellow flame. In their turn, barium gives green, calcium - orange, strontium - red and copper - blue.
