FAQs on JEE Main 2025-26 Mock Test Preparation: Classification of Elements and Periodicity in Properties
1. What is the periodic law and how did it lead to the development of the modern periodic table?
Periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. The modern periodic table arranges elements in order of increasing atomic number, reflecting the periodic recurrence of properties. This arrangement helps recognize trends like atomic size, ionization enthalpy, and electronegativity.
2. What are periodic properties? List some examples.
Periodic properties are characteristics of elements that recur periodically when arranged by atomic number. Key examples include atomic radius, ionization energy, electron affinity, metallic character, and electronegativity. These properties repeat in predictable patterns across periods and groups in the periodic table.
3. How does atomic radius change across a period and down a group?
As you move across a period from left to right, the atomic radius decreases due to increased nuclear charge pulling electrons closer. Down a group, the atomic radius increases because additional shells of electrons are added, outweighing the increased nuclear charge.
4. Why does ionization enthalpy generally increase across a period?
Ionization enthalpy increases across a period because the atomic size decreases and nuclear charge increases, making it harder to remove an electron from the outer shell. This means more energy is required to ionize atoms as you move left to right across a period.
5. Define electronegativity and explain its periodic trend.
Electronegativity is the ability of an atom to attract shared electrons in a chemical bond. It increases across a period due to smaller atomic radii and higher nuclear charge, and decreases down a group due to increasing atomic size and shielding effect.
6. What is the difference between Mendeleev’s periodic table and the modern periodic table?
Mendeleev’s table arranged elements by increasing atomic mass and predicted undiscovered elements, but some placement errors occurred. The modern periodic table arranges elements by atomic number, resolving these inconsistencies and providing a more accurate reflection of element properties and trends.
7. What are s, p, d, and f blocks in the periodic table?
s-block contains elements where the last electron enters an s orbital (Groups 1 & 2). p-block contains elements with last electron in a p orbital (Groups 13-18). d-block (transition elements) have the last electron entering a d orbital (Groups 3-12), and f-block elements (lanthanides and actinides) have electrons entering an f orbital.
8. How does metallic character change in the periodic table?
The metallic character decreases across a period from left to right due to increased ionization energy and increases down a group as atoms lose electrons more easily because of larger atomic radius and shielding effect.
9. What is electron affinity and how does it vary in the periodic table?
Electron affinity is the energy change when an atom gains an electron. It becomes more negative (increases) across a period due to higher nuclear attraction, but becomes less negative (decreases) down a group as atomic size increases and the added electron is farther from the nucleus.
10. Why are noble gases placed in Group 18 in the modern periodic table?
Noble gases are placed in Group 18 because they have completely filled outermost shells, making them highly stable and chemically inert. Their unique electronic configuration sets them apart from other element groups.
11. Why do elements in the same group show similar chemical properties?
Elements in the same group have the same number of valence electrons and similar electronic configurations, leading to similar chemical properties such as reactivity and valency.
12. How can you identify an element’s position in the periodic table from its electronic configuration?
The period number corresponds to the highest principal quantum number (n) in the configuration. The group number (for main group elements) can be identified from the number of valence electrons. For example, an element with configuration 2,8,7 is in Period 3, Group 17.
