Did Mendeleev organize the elements by atomic mass or atomic number?
Mendeleev arranged elements in order of increasing mass. Later modern periodic table was discovered that contains elements arranged by atomic number.
What elements have more predictable properties main group elements or transition elements?
main group elements
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Are there about 100ndifferent elements?
There is at least 117 different elements, and more are still to be discovered.
What is the element that has more protons of any element in group 15?
The expected answer is element 115, Ununpentium, if that has been discovered. Among stable elements, the answer would be bismuth.
Are the element sin the periodic table the only elements discovered?
Yes. The elements in the Periodic Table are the only elements that have been discovered. However, we are still discovering and synthesising more elements.
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
Are there no new elements to be discovered?
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may be discovered.
Are group one or group two more reactive?
Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
What elements did Marie Curie discovered?
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
What is logical element?
A logical element refers to a fundamental component used in logic circuits and systems, typically found in digital electronics. These elements perform basic logical operations such as AND, OR, and NOT, which are essential for processing binary information. They serve as building blocks for more complex circuitry, allowing for decision-making processes in computing and automation. Overall, logical elements are crucial for implementing logical functions in various technological applications.
