This question is about the Periodic Table. In 1864 John Newlands produced a version of the Periodic Table. Newlands placed all the elements that had been discovered into his table of octaves. He thought every eighth element when put in order of their atomic weight was similar.
Table 3 shows part of Newlands’ version of the Periodic Table. Table 3
Octaves
(2 marks)
H 1 Li 2 Gl 3
F 8 Na 9 Mg 10
Cl 15 K 16 Ca 17
Co and Ni 22 Cu 23
Zn 25
Br 29 Rb 30 Sr 31
Pd 36 Ag 37 Cd 34
I 42
Cs 44
Ba and V 45
Pt and Ir 50 Tl 53
Pb 54

Suggest one reason why Newlands placed hydrogen in the octave shown.

what does the table look like

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
