Many chemists and physicists during the centuries contributed to this conception.
The very intellegent person who invented the PB form of the table of elements was Isaac Newton. He invented the Table of Elements by testing all of the elements and recording the results.
Elements are discovered, they are not invented.
The Periodic Table Of Elements Was Invented iN 1869, By A Russian Chemist Named Dmitri Mendeleev.
it was invented so people could see the elements.
Different people found different elements.
It wasn't invented. It's a natural process that was discovered in heavier elements.
Yes, atoms of different elements have a different number of protons.
Different elements have different numbers of protons. The number of protons identifies the element.
Many different people invented different wrenches at widely different times.
Because different elements have different numbers of protons, which determines the atomic number.
The gaps represented the elements which were not discovered. When the elements were invented, they were placed into these gaps.
who said this atoms of different elements are different
