Two different will always have different numbers of protons as the number of protons defines which element an atom is.
However, two isotopes of different elements can have the same number of neutrons.
For example the isotope carbon-13 has 6 protons and 7 neutrons while nitrogen-14 has 7 protons and 7 neutrons.

Two isotopes of the same element have the same number of what?
They have the same number of protons and different number of neutrons.
What are atoms of the same element but have different sums of protons and neutrons?
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.
Isotopes exist because atoms of the same element can have a different numbers of what?
Isotopes are different atoms of the same element with the same number of protons (proton number) but different in number of neutrons. Given that nucleon number is equal to the sum of proton and neutrons in the nucleus of an atom, isotopes have different nucleon number due to difference in number of neutrons.
What does every atom in a particular element have in common?
They all have the same number of neutrons. All atoms of a given element have a specific number of protons. That is what gives an element its elemental identity. But we know that different atoms of a given element can have different numbers of neutrons. These different atoms of the same element are the isotopes of that element. All the atoms of a given isotope of a given element will have the same number of protons and will have the same number of neutrons. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties. all isotopes of an atom have same number of proton but they have different number of neutron so they have same chemical properties and different physical properties.
What defines what an element is?
Elements are chemically defined by the number of protons present in the nucleus. The atomic number of an element is merely the number of protons that are in the nucleus. There are various isotopes of the same element, which just means the amount on neutrons has changed, however the protons remain the same.
Isotopes of the same element differ in the number of what-?
Only the neutron number is different, same proton and electron number.
Do mass of proton vary for different elements?
The number of protons is different for each element, but the mass of each individual proton is always the same.
Two isotopes of the same element have the same number of what?
They have the same number of protons and different number of neutrons.
What are atoms of the same element but have different sums of protons and neutrons?
The Proton number defines the element, so there cannot be two atoms of the same element with different proton numbers, because they will be, by definition, different elements. Neutron numbers can differ though. When one element has different neutron configurations, these are called Isotopes.
Can 2 isotopes of the same element differ in the number of neutrons?
YES. The very definition of isotopes are atoms of the same element with the same number of proton (same atomic number) but different numbers of neutrons, therefore different mass numbers.
What do all atoms of a certain element have the same number of?
Proton Number
How atoms of the same element can be different?
An element by definition refers to all atoms with the same number of protons; so any atom with 1 proton is the same element as all other atoms with one proton; which would be helium. And then, all atoms with 2 protons would be the same element; hydrogen. But the atoms that have 1 proton and the atoms that have 2 protons cannot be the same element.An ion is an element with a different amount of electrons, where if it is a positive ion it is missing an election compared to a "normal" element and if it is a negative ion it would have an extra election compared to a "normal" element.An isotope is a member of the same element but it has a different number of neutrons.
Do isotopes of an element have the same atomic number?
They have the same number of protons (and electrons) - so proton number. They have a varying number of neutrons - Mass number. Proton number and Atomic number mean the same things, so Isotopes of an element have the same atomic number.
Is a Proton of one element exactly the same as the Proton of a different element?
All protons are identical. What is different between elements is the number of protons.
Does atom of the same element have the same number of proton?
Yes that is true Every atom of a given element does have the same number of protons.
What do two different neutral Isotopes have the same elements in common?
The proton and electron number are equal for all isotopes of the same specific element.
Are atoms with the same atomic number atoms of the same element?
yes. Isotopes of an element have the same number of protons, thus electorns, thus the same chemical properties. Where isotpes differ is in the number of neutrons. Consider hydrogen, atomic number 1, atomic weight 1, 1 proton, 1 electron vs duterium, atomic number 1 atomic weight 2, 1 proton, 1 electron, 1 neutron. H2O = water D2O = heavy water
