Question

Can atoms of two different elements have the same number of protons?

Answer 1

ANSWER :

Atoms of different elements cannot have the same number of protons .

EXPLANATION :

↪ Atomic number denotes the number of protons in an atom .

↪ The atomic number is different for all elements and hence there is a periodicity of elements in the Modern Periodic Table .

↪ The atomic number increases by one as we move across the periods from left to right .

↪ This is called periodicity or occurrence of similar properties in regular intervals .

↪ Periodicity occurs only when elements are arranged in increasing order of atomic numbers.

Answer 2

no. of protons is actually equal to the atomic number of the element.

yes,two elements can have same atomic number and are named isotopic elements.
