In the periodic table, the most reactive metals are found a. in group 1, the first column on the left. b. in period 1, the first row across the top. c. in groups 13 through 16 in the center. d. in periods 6 and 7 at the bottom.

Group 1, the first column on the left.

The correct answer is Option a.

Explanation:

Chemical reactivity is defined as the property of an element to loose or gain electrons.

Metals are the elements which loose electrons and hence, their chemical reactivity will be the tendency to loose electrons.

Their chemical reactivity decreases as we move from left to right in a period because the valence shell come closer to nucleus as we move from left to right. So, removal of electron in the valence shell becomes difficult due to greater attraction between nucleus and valence electron.

Their chemical reactivity increases as we move from top to down the group because the electron gets added up in the new shell. So, the electron in the outermost orbital gets far away from the nucleus. And hence, the electron will be lost easily.

Hence, the correct answer is Option a.

no, i was listening to water by schoolboy q while and i saw this question

explenation:

water isn't wet. wetness is a description of our experience of water; what happens to us when we come into contact with water in such a way that it impinges on our state of being. we, or our possessions, 'get wet'. a less impinging sense experience of water is that it is cold or warm, while visual experience tells us that it is green or blue or muddy or fast-flowing. we learn by experience that a sensation of wetness is associated with water: 'there must be a leak/i must have sat in something.'
