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
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.
What did Dalton contribute to atomic structure?
dalton's contribution is ................................... ..........................................................................................................................................
How do you convert from grams to atoms and from mass to atoms?
1 atomgram of a chemical element has 6,02214129(27)×1023 atoms. 1 atomgram=atomic weight of a chemical element exprimed in grams.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
Can two atoms of same element ever have different atomic numbers?
The atomic number is identical for all the isotopes of the same chemical 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

What makes a compound and an element?
A chemical compound is formed from chemical elements.A chemical element is formed from atoms; atoms contain an atomic nucleus (protons and neutrons), electrons and...vacuum.
What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
How do you convert from grams to atoms and from mass to atoms?
1 atomgram of a chemical element has 6,02214129(27)×1023 atoms. 1 atomgram=atomic weight of a chemical element exprimed in grams.
What is the atomic radius of a chemical element?
The atomic radius, is the measured size of the atoms of a chemical element. Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.
What is a substance that cannot be separated or broken down into simpler substance by chemical means all atoms of an element have the same atomic number?
1. You think probable to the atoms of chemical elements. 2. Al l atoms of the same chemical element have the same atomic number.
What are atoms of an element have the same atomic number but a different atomic mass?
isotope
What major contribution did john Dalton made to the atomic theory?
Dalton's Atomic Theory 1) All matter is made of atoms. Atoms are indivisible and indestructible. 2) All atoms of a given element are identical in mass and properties 3) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
