Classification of Elements and Periodicity in Properties MCQ questions with answers
The first 3 of 20 questions. Unlock the series for the rest, each with a solution.
Q1. The f-block elements of the periodic table are collectively known as:
आवर्त सारणी के f-ब्लॉक तत्व सामूहिक रूप से किस नाम से जाने जाते हैं:
- A. Bridge elements / सेतु तत्व
- B. Representative elements / प्रतिनिधि तत्व
- C. Inner transition elements / आंतरिक संक्रमण तत्व
- D. Transition elements / संक्रमण तत्व
Solution
The lanthanoids and actinoids that make up the f-block are called the inner transition elements, as the differentiating electron enters the deeply buried (n−2)f subshell.
f-ब्लॉक बनाने वाले लैंथेनॉइड और ऐक्टिनॉइड को आंतरिक संक्रमण तत्व कहा जाता है, क्योंकि विभेदक इलेक्ट्रॉन गहराई में दबे (n−2)f उपकोश में प्रवेश करता है।
Q2. In the long form of the periodic table, the d-block (transition elements) consists of how many groups?
आवर्त सारणी के दीर्घ रूप में, d-ब्लॉक (संक्रमण तत्वों) में कितने समूह होते हैं?
- A. 14
- B. 10
- C. 18
- D. 8
Solution
The d-block spans groups 3 to 12, i.e. 10 groups, corresponding to the filling of the five (n−1)d orbitals.
d-ब्लॉक समूह 3 से 12 तक विस्तृत है, अर्थात् 10 समूह, जो पाँच (n−1)d कक्षकों के भरने के अनुरूप है।
Q3. Consider the following statements about the long form of the periodic table: 1. It contains 7 periods and 18 groups. 2. The sixth period contains 32 elements. 3. When complete, the seventh period also accommodates a maximum of 32 elements. Which of these statements is/are correct?
आवर्त सारणी के दीर्घ रूप के बारे में निम्नलिखित कथनों पर विचार कीजिए: 1. इसमें 7 आवर्त और 18 समूह होते हैं। 2. छठे आवर्त में 32 तत्व होते हैं। 3. पूर्ण होने पर, सातवाँ आवर्त भी अधिकतम 32 तत्वों को समाहित करता है। इनमें से कौन-सा/से कथन सही है/हैं?
- A. 1 and 2 only / केवल 1 और 2
- B. 1 and 3 only / केवल 1 और 3
- C. 1, 2 and 3 / 1, 2 और 3
- D. 2 and 3 only / केवल 2 और 3
Solution
The long form has 7 periods and 18 groups; both the sixth and the (complete) seventh periods contain 32 elements, as each involves filling of s, p, d and f subshells.
दीर्घ रूप में 7 आवर्त और 18 समूह होते हैं; छठे और (पूर्ण) सातवें दोनों आवर्तों में 32 तत्व होते हैं, क्योंकि प्रत्येक में s, p, d और f उपकोशों का भरना शामिल है।
