Waves Project
Now that you're all experts in understanding the different types of waves, how they move and
change direction, and how to describe their characteristics, tell me:
What are some of the ways that you see waves used in your everyday lives?
Your project must include the following information in detail:
• How is it categorized: mechanical or electromagnetic waves? Why?
• Is it a longitudinal or transverse wave? Why?
• Describe interesting facts (3) about the wave
• Identify the characteristics of its use everyday, in what industry or devices? Explain
• How is it important to the world? Explain

the answer to your question is c.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
