This chart shows characteristics of three different waves, all with the same wavelength of 10 m but moving at different frequencies. A 3-column table with 2 rows titled Waves at Different Frequencies. The first column has entries Wave X and 6 hertz. The second column has entries Wave Y and 0.5 hertz. The third column has entries Wave Z and 2 hertz.

Which statement is best supported by the information in the chart?

Wave Y is moving the fastest.
Wave X is moving the fastest.
All of the waves are moving at the same speed.
All of the waves have the same value of wavelengths per second.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

i don't know people like to fight everywhere rip.
