Why do all atoms of an element have the same chemical prperties?
Because they are all the same type of atoms. Oxygen is an element. If you have 10 oxygen atoms, they will all behave like oxygen, since they are the same element.
Are oxygen atoms different to oxygen atoms?
No, oxygen atoms are all the same. Each oxygen atom has 8 protons in its nucleus and is chemically identical to every other oxygen atom.
Do oxygen have the same mass?
yes the are all the same
John Dalton concluded that all the atoms of a single what have the same mass?
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
Is it true that all atoms have the same mass?
It is not true !!
What's the difference between an atomic number in the mass number of an Atom?
All the atoms of a particular element have the same atomic number (number of protons). The atoms of different elements have different numbers of protons. For example, all oxygen atoms have 8 protons and all sodium atoms have 11 protons. The mass number of an atom is the total number of protons and neutrons it contains.
What do you know about all the atoms in the element oxygen?
2 atoms of oxygen joined togetherBy mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At STP, two atoms of the element bind to form dioxygen.

Does a carbon atom have the same mass as an oxygen atom?
No all oxygen atoms do not have the same mass as you can get isotypes of the same element which are still called the same except that they can have more or less neutrons than the standard model this is why the weight is refered to as an average mass
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.
Is a 16.00-g sample of oxygen atoms contains the same number of particles as a 4.003-g sample of He atoms?
Yes. 16.00g of oxygen is its molar mass, which is the mass of one mole of oxygen. 4.003g is the molar mass of helium, which is also the mass of one mole of helium. One mole of anything is 6.022 x 1023. One mole of oxygen atoms is 6.022 x 1023 atoms of oxygen and one mole of helium atoms is 6.022 x 1023 atoms of helium.
What scientific instrument was used to discover that not all atoms of neon have the same mass?
The mass spectrometer was used to discover that not all atoms of neon have the same mass. This instrument separates and measures atoms based on their mass-to-charge ratio, allowing scientists to identify isotopes of elements like neon that have different masses.
