Canada and england can be found at approximately the same latitude. differentiate between the two climates.
a.) canada is cold and snowy for much of the year and so is england.
b.) canada is cold and snowy for much of the year, but england has tropical temperatures in the summer.
c.) canada is cold and snowy for much of the year, but england has mild winters, usually without snow.

C.) Canada is cold and snowy for much of the year, but England has mild winters, usually without snow.

Explanation:

Eventhought they are located on the same latitude, the main difference between England and Canada´s climates are due to the combination of jet streams and ocean currents, jet streams are the path that warm air follows from the equator to the poles and ocean currents carry out cold air, Canada gets more cold polar airs, and England gets more warm air from the poles that creates for mold winters without snow, while it creates a cold and snowy climate in Canada.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
