The trend of ionization energy in the periodic table is decreasing from right to left and from top to bottom. In this case, we are given with elements <span>K, Ca, Ge, Se, Br, Kr and see the periodic table to check the trend. The answer from highest to lowest Kr, Br, Se, Ge, Ca, and K</span>
B) It will accelerate to the right because 500 N> 300 N
<span>V equals one-third times pi times r squared times h</span>
Na and Cl together form the compound
NaCl2
