Welcome back to BYJU’S Sunday Challenge! In this edition, we meander through the most elementary and fundamental building block of Chemistry and scoop out some tantalizing trivia. This weekend, we quiz you on the Periodic Table.
You can take a shot at the questions and field your guesses in the comments section below. Answers will be revealed on subsequent Sundays in the comment section. The fastest entries to get all questions correctly will receive a special goodie bag from BYJU’S. To see the winners of the 19th edition of the Sunday Challenge, click here.
Ready? Here are your questions:
There are two elements in the periodic table named after the Greek words for the Sun and the Moon. Which ones are they?
Which noble gas shares its name with the home planet of the superhero whose birth name is Kal-El?
The man to the left of Albert Einstein in the picture below was a Danish physicist who won the Nobel Prize in Physics in 1922 for his studies on the structure of the atom. The element with atomic number 107 and the symbol ‘Bh’ is named after him. Identify him.
Dmitri Mendeleev left a few gaps in his periodic table for elements that were yet to be discovered. One such element he called eka-boron and derived that its atomic mass would be 44. This element was later discovered and isolated in 1879 by Swedish chemist Lars Fredrik Nilson. He was unaware of Mendeleev’s prediction and named the element as a reference to the region in Northern Europe where he discovered it. How do we know the element today?
Which is the only letter of the English alphabet that cannot be found in the periodic table?
Take your guesses in the comments section below. Winners of this edition, along with the answers will be revealed next Sunday in the comments section, so keep your eyes peeled!

3.He is Neils Bohr…..Bohrium was chemical element named after him
4. Gallium…..The existence of gallium had been predicted in 1871 by Dmitri Mendeleev, the Russian chemist who published the first periodic table of the elements. Mendeleev noted a gap in his table and named the missing element “eka-aluminum” because he determined that its location was one place away from aluminum in the table.

1️⃣ Helium is derived from the Greek word heliuz ( which means SUN ) and Selenium is derived from the Greek word Selene ( which means MOON )🔹
2️⃣ Kryton is the noble gas that shares its name with the home planet of the superhero whose birth name is Kal-El🔹
3️⃣ Neil Bohr is the man left of Albert Einstein in the picture . He was a Danish physicist who won the Nobel Prize in Physics in 1922 for his studies on the structure of the atom. The element with atomic number 107 and the symbol ‘Bh’ is named after him. The Element’s Name is Bohrium 🔹
4️⃣ Scandium is the element Dmitri Mendeleev called eka-boron when he left a few gaps in his periodic table for elements that were yet to be discovered and derived that its atomic mass would be 44. This element was later discovered and isolated in 1879 by Swedish chemist Lars Fredrik Nilson. He was unaware of Mendeleev’s prediction and named the element as a reference to the region in Northern Europe where he discovered it 🔹
5️⃣ ” J ” is the only Letter of the English Alphabet that cannot be found in the periodic table . But even in Countries like Norway , Denmark etc… Uses The Word Jod ( J ) for Iodine . But According to IUPAC Iodine Symbol is ” I ” 🔹

(1)The answer of first one is helium derived from greek word hydros meaning sun whose atomic number is 2 and other is tellurium atomic number is 52 which is after antimony (51) in periodic table
(2)The answer is Krypton(36)atomic number and is followed by rubidium as per the cartoon it is home of superman and it is a fictional planet
(3)Actually, the one who is sitting near to einstein is neil bohr after whom the element named is neil bohr and one element einstenium (99) is also named after einstein followed by ferium(100)
(4) The next one is scandium and current 44 th is ruthenium
(5)As per my thinking the letter is J
