Is it possible to have an element having atomic number 1.5 placed between hydrogen and helium ? |
|
Answer» No, because in the modern periodic table, elements are placed in increasing order of their atomic numbers. Atomic number is always a simple whole number as half electron or half proton cannot exist. It can be either 1 or 2.So, there can be no element with atomic number 1.5. |
