When 2 atoms appear to have same atomic mass?
When they are of the same 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
Does H2O made of 2 atoms of the same element?
No, H2O is made of two hydrogen atoms and one oxygen atom.
If you have 2 atoms have the same number of protons but different number of neutrons what will they will have the same?
No, they will not be considered isotopes since isotopes are atoms of same element (therefore, have same number of protons). However, the types of atoms which have same atomic mass number but different no. of protons, they are called isobars. Eg:- Calcium and Argon = =
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons?
They are called Isotopes
When 2 atoms appear to have same atomic mass?
When they are of the same element.
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.
What could be different about 2 or more atoms of the same atom?
Did you mean, "What could be different about 2 or more atoms of the same element?" If you did, the answer is that they can have a different number of neutrons.
Do ions of the same element have the same number of valence electrons?
Atoms of the same element do, but some ions do not. Iron forms 2+ and 3+ ions

How common is lawrencium?
Lawrencium is an artificial element obtained at the level of 1 000 -2 000 atoms.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons?
They are called Isotopes
Where are the mass variances in 2 atoms of the same element and why do they occur?
If the chemical element has isotopes, each isotope has a specific and different atomic mass.
How many atoms are in 2 mole of potassium?
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
Is aluminium oxide an element or compound?
Aluminium oxide is a compound 'cos it's made of 2 kinds of atoms. If it has to be an element, it has to be made of same kind of atoms like graphite/diamond/H2(gas).
