FAQs on Period-wise Electronic Configuration

Question 1

1. What is the electronic configuration of an atom?

Accepted Answer

Ans. The electronic configuration of an atom refers to the arrangement of electrons in its various atomic orbitals. It specifies the number of electrons present in each shell and subshell of the atom.

Question 2

2. How can I determine the electronic configuration of an element?

Accepted Answer

Ans. The electronic configuration of an element can be determined by using the periodic table. Each element's electronic configuration is based on the number of electrons it possesses. The periodic table provides information about the number of electrons present in each shell and subshell.

Question 3

3. What is the significance of electronic configurations in chemistry?

Accepted Answer

Ans. Electronic configurations are significant in chemistry because they determine the chemical properties of an element. The arrangement of electrons in different orbitals affects the element's reactivity, bonding behavior, and overall chemical behavior.

Question 4

4. How does the electronic configuration change across periods in the periodic table?

Accepted Answer

Ans. The electronic configuration changes across periods in the periodic table as the number of electrons increases. Each period represents a new shell being filled with electrons. As you move from left to right across a period, the number of electrons in the outermost shell increases, leading to changes in the element's chemical properties.

Question 5

5. Can the electronic configuration of an element be predicted?

Accepted Answer

Ans. Yes, the electronic configuration of an element can be predicted based on its position in the periodic table. The periodic table follows certain trends and patterns, allowing us to determine the arrangement of electrons in an element's orbitals. However, it is important to note that exceptions and anomalies exist, especially for transition metals and some heavier elements.
