Answer 1

To predict the order of increasing electronegativity without using a figure, you can use the periodic trend. Electronegativity generally increases from lower left to upper right in the periodic table.

Step-by-step explanation:

In order to predict the order of increasing electronegativity without using a figure, you can use the periodic trend. Electronegativity generally increases from lower left to upper right in the periodic table. So, in each group of elements, the order of increasing electronegativity can be determined based on their positions in the periodic table.

For example:

a. C, N, O: The order of increasing electronegativity is C < N < O.

b. S, Se, C: The order of increasing electronegativity is S < Se < C.

c. Si, Ge, Sn: The order of increasing electronegativity is Si < Ge < Sn.

d. Ti, S, Ge: The order of increasing electronegativity is Ti < S < Ge.
