Question

nane any two elements that can take or give equal number of electrons​

Answer 1

Answer:

Consider helium gas which is having 2 protons and two electrons. That is, its atomic number is 2.

Now, if you find any other atom which is having 2 prtons and two electrons, then why would you call it by any other name…. it is already named as HELIUM, isn't it?

Properties of elements depend upon their atomic numbers (modern periodic law). Therefore any two atoms which are having same number of protons and electron are having same properties. It follows that the two atoms belong to same element.

Therefore, 2 elements can never have same atomic number.Consider helium gas which is having 2 protons and two electrons. That is, its atomic number is 2.
