Question

1. Using the periodic table and your knowledge of patterns and trends on the table, which of the following elements is the best conductor of electricity?
A. Titanium **

B. Silicon

C. Oxygen

D. Argon

2. Using the periodic table and your knowledge of patterns and trends on the table, which of the following elements is the most reactive?

A. Titanium **

B. Silicon

C. Oxygen

D. Argon

3. Using the periodic table and your knowledge of patterns and trends on the table, which of the following elements has the highest electronegativity?

A. Titanium

B. Silicon

C. Oxygen **

D. Argon

Answer 1

From the periodic table as well as the patterns and trends on the table, the correct option are:

1. the best conductor of electricity is Titanium; option A
2. the most reactive element is oxygen; option C
3. the elements that has the highest electronegativity is oxygen; option C

What is the periodic trends in the periodic table?

Periodic trends in the periodic table refers to the variation in character which is observed in the periodic table as one moves across the periodic table from left to right across a period or down a group in the periodic table.

The periodic trend observed is that reactivity of metals increase down a group and from right to left across a period.

For non-metals,  reactivity of non-metals increase from down to top in a group and from left to right across a period across a period.

Considering the given questions;

1. From the periodic table as well as the patterns and trends on the table, the best conductor of electricity is Titanium since it is the only metal in the list.

2. The most reactive element is oxygen because it is a non-metal found to the top-left of the periodic table.

3. The elements that has the highest electronegativity is oxygen because it is a non-metal found to the top-left of the periodic table.
