What did Dolton discover about atoms?
This is Dalton's Atomic Theory:Dalton's Atomic Theory1) All matter is made of atoms. Atoms are indivisible and indestructible.2) All atoms of a given element are identical in mass and properties3) Compounds are formed by a combination of two or more different kinds of atoms.4) A chemical reaction is arearrangement of atoms.
What does adding s neutron to an atoms nucleus do to the atoms mass?
Increases it by one mass unit.
What is the mass in grams of 2x1012 atoms of potassium?
What is the mass, in grams, of 2 × 1012 atoms of potassium?
Why doesn't the mass change in physical and chemical changes?
Under normal circumstances it is impossible to make atoms split apart, ie so that mass cannot be lost. This is a scientific law. In a Nuclear reaction mass can be converted into energy, e=mc2. This means that mass will be lost.
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
What is the name of the scientific instrument used to find the mass of an object?
A Triple Beam Balance is used to find the mass of an object.
What is an instrument for measuring mass?
Scales - depending on the size of the mass maybe 'balance scales' or 'bathroom scales' or 'kitchen scales'. Mass is the proper scientific word for 'weight'
Did bohr discover that the atoms mass came frome neutrons and protons?
Rutherford discovered that almost entire mass of an atom is located in the nucleus, and then, the neutron was discovered by Chadwick.
What does a double pan balance measure?
mass. That scientific, or laboratory instrument, is usually called a Beam Balance.
What do you discover when determining mass and volume?
You might discover that solids have mass and they have volume.

Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
What is the most common instrument used to measure isotope?
The most common instrument used to measure isotopes is a mass spectrometer. Mass spectrometry allows scientists to accurately determine the mass and abundance of isotopes in a sample. It works by ionizing the atoms in the sample and separating them based on their mass-to-charge ratio.
Are rare earth elements useful in scientific notation?
just like any other elements if you are talking about the size or mass of one or a few atoms, then you probably want to ust scientific notation.
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Is fusion nuclear decay or nuclear synthesis?
Fusion is nuclear synthesis, combining atoms of lesser mass into atoms of greater mass. Decay is reducing the mass of larger (unstable) atoms to form atoms of lesser mass.
