How do you know if two atoms are from the same element?

Two atoms are from the same element if they have the same number of protons in their nuclei. This is the defining characteristic that determines an element's identity. For example, all carbon atoms have 6 protons, so any two atoms with 6 protons are considered to be the same element, carbon.


How is it possible for two different atoms to have the same atomic mass?

They would have to be atoms of the same element, and the same isotope of that element.


If two elements have the same number of protons but different number of neutrons can they be atoms of the same element.?

Yes. If two atoms have the same number of protons then by definition they are the same element.


What two atoms of the same element come together what do they form?

When two atoms of the same element come together, they form a molecule of that element. For example, when two oxygen atoms come together, they form a molecule of oxygen (O2).


Two atoms are isotopes of the same element which should be the same for these two atoms?

The number of protons in the nucleus is the same for both isotopes since they are of the same element. Isotopes of the same element have the same number of protons (which determines the element) but a different number of neutrons, leading to a difference in atomic mass.


Are two atoms that have the same number of protons the same element?

Yes. The number of protons defines the element.


Is The oxygen molecule made up of three atoms of the same element?

No, the oxygen molecule is made up of two atoms of the same element, oxygen.


Two Atoms of the same element when bonded form what?

Diatomic


Does molecule contain two atoms of the same element?

yes


What atoms are in a hydrogen molecule?

Molecular hydrogen has two atoms, both which are of the same element - hydrogen.


Why is the covalent between two atoms of the same element a non polar bond?

A nonpolar covalent bond between two atoms of the same element occurs when they have the same electronegativity, leading to equal sharing of electrons. This results in a symmetrical distribution of charge, making the bond nonpolar.


The mass of any two atoms of the same element is always the same?

The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
