Solar panels ( Solar-powered photovoltaic )
Answer:
It depends on where it's located on the periodic table.
Explanation:
Metals are on left side of the periodic table except Hydrogen (H), which is a nonmetal, then there's the staircase, which has the metalloids, and on the right of the staircase are the nonmetals.
4 3 and 5 are wrong:)
4 is true and 5 is false
4. insulators are really thick materials that keep electrons within their space.
For example, a charger the rubber is the insulators and the electrons are flowing inside of the charger so you don't get shocked.
5. without the force of attraction, there are no atoms:)
for number 3, its a trick question
Hope this helped!
(learned these this year so I didn't forget them:)
Answer:
your answer should be the bottom
sorry if im wrong
Explanation:
Understanding chemistry and its principles enables us to predict and understand various properties of substances. For example, because we know that ionic bonds are very strong and difficult to break, we know that any substance that has these bonds will have a high melting point, because melting is a process that requires the intermolecular bonds present in the solid state to be broken. This can be applied to table salt, sodium chloride, which has an ionic structure and a melting point of almost 800 degrees Celsius. Similarly, many other properties and characteristics may be predicted using concepts of chemistry.
