If the length of a wave is doubled, what will happen to the value of the frequency? (c = λv) A. it will increase B. it will decrease C. it will stay the same

B

Explanation:

If the frequency is doubled, the wavelength is only half as long.

If the wavelength Doubled, the frequency is reduced.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

can you list the answers so i can answer
