Unit 2 - Inv. 1: What is happening when a spark occurs? (v2) Report for

Analysis: What is an ion? Describe what happens to the electrons in an atom when they absorb energy (from the flame)?  Why does this produce a bright-line emission spectrum (rather than a continuous spectrum)? In terms of atomic structure, why does each metal ion produce a different color flame? What difficulties are there in identifying metal ions with a flame test?  How could you improve the specific identification of the metal ions during a flame test? If it can be determined from the flame test results, what are the identities of the two unknown liquids? What might be some practical (and exciting) applications of metal containing compounds that create different colors of light while burning?  Explain.

Solve correctly please.

4. Describe how energy that came to Earth many years ago in the form of radiant energy can be used today to create music in your radio.

Please help with question 2

Please help, I'm really confused.

Subject: chemistry

I am currently in Anatomy and Physiology 101. We are in the Chemistry section of our lab book, and I came across a question I wasn't too sure about. The question is; "Do metals donate or accept electrons? What do they become after they donate/accept electrons?" For this question I put that metals both accept and donate elcetrons, and after this they become Ions. Is this correct?

Please help with all parts

Does the Aluminum (Al) ion gain or lose electrons? a Lose because it is easier for Aluminum (Al) to get to the Noble Gases losing electrons than gaining electrons Ob Lose because Aluminum has a negative charge Gain because it's on the same level as Argon Gain because it's easier for Aluminum (Al) to get the Noble Gases gaining electron than losing electrons Submit Saved at 8:41 am Support | Schoology Blog I PRIVACY POLICY I Terms DELL

A carbon-oxygen double bond in a particular molecule absorbs electromagnetic radiation that has a frequency of 4.3 x 1014 s-1. What is the wavelength of this radiation in nanometers, and what type of electromagnetic radiation is this? (radio, IR, UV, visible, etc)

Why do most metals make good electric conductors? A Metals have low specific heat. B Metals attract positive ions. C The electrons in metals flow easily between atoms. D The nuclei of metals easily donate protons.

Wavelength (nm) I'm not sure what equation I can come up with other than the one generated with my graph. Can you please show me the calculations that were used to find this equation? Give an equation that relates energy to wavelength. Explain how you arrived at your equation.

Why did you add 3 electrons to the Bismuth equation if the solid had no charge and the right side only had a plus 1 charge? Why not add only one electron?
