Chapter 4: Problem 40

The total number of elements present in the 6 th period is (a) 18 (b) 31 (c) 32 (d) 17

Short Answer

Expert verified
Answer: There are 18 elements in the 6th period of the periodic table.

Step by step solution

01

Identify the period in question

In this exercise, we want to know the total number of elements present in the 6th period.
02

Recall the structure of the periodic table

The periodic table is constructed of periods and groups. Elements in each period have the same number of electron shells. The number of electron shells increases as we move down the table, and this determines the number of elements in each period.
03

Identify the number of electron shells for elements in the 6th period

Since elements in the 6th period have 6 electron shells, we can use this information to determine the number of elements in this period.
04

Understand the electron shell structure and distribution

Electrons are distributed amongst the shells in the following order: 1. The first electron shell can hold up to 2 electrons. 2. The second electron shell can hold up to 8 electrons. 3. The third electron shell can hold up to 18 electrons. 4. The fourth electron shell can hold up to 32 electrons. 5. The fifth electron shell can hold up to 32 electrons. 6. The sixth electron shell can hold up to 18 electrons. Note that, in reality, the distribution is more complex, but this simplified view suits our purpose.
05

Determine the number of elements in the 6th period

Since the 6th electron shell can hold 18 electrons, there are 18 elements in the 6th period, as each element in the same period has a unique electron configuration. Hence, the correct answer is (a) 18.
