Question

5. Elements are different because they contain different numbers of protons.

Answer 1

Answer:

True

Explanation:

The number of electrons are what determine an atom.

The number of electrons = number of protons

so the elements are different.

If the number of neutrons are different but the number of electrons and protons are same they are of the same element.

But here the number of protons are different so this is another element.
