1.) What are radio waves? Describe how radio telescopes function.

2.) What are the advantages of using a radio telescope instead of a reflecting or refracting telescope?

3.) Using internet resources, describe the ways radio waves are used on Earth.

4.) How do radio telescopes help advance our knowledge of our universe?

it is a solid

explanation:

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
