The logical way is to be remembered that chemical properties of elements have a periodic character.
main group elements
Group 1 elements are more reactive than that of group 2 elements.
There is at least 117 different elements, and more are still to be discovered.
no there are more which have not been discovered
yes there is
Yes. The elements in the Periodic Table are the only elements that have been discovered. However, we are still discovering and synthesising more elements.
The expected answer is element 115, Ununpentium, if that has been discovered. Among stable elements, the answer would be bismuth.
The elements from the group 12 are not the most reactive chemical elements.
No. Uranium is the heaviest naturally occurring element. More elements can be prepared artificially. New isotopes of the element may 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.
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.
Not if more elements are discovered.
