What was lavoisiers greatest contribution to science?
His atomic theory. He was the one who thought that there were atoms in everything.
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?
Which has the greatest number of atoms- 45 grams of Mg 45 grams of F 45 grams of P or 45 grams of Na?
In order to figure out how many atoms are in each sample, you would take 45, multiply it by 6.02 × 1023, and divided by the atomic mass. Since two of the numbers (45 and 6.02 × 1023) will be constants in all of the samples, the number of atoms will differ in each sample due to the atomic mass. 45 × (6.02 × 1023) / atomic mass in grams = number of atoms You could punch out all the numbers to see which sample has the greatest number of atoms, but it is easier to find the atomic mass for all of them and see which one is smaller. A larger atomic mass will mean the equation will be divided by a larger number, meaning the number of atoms will be smaller. So the smallest atomic mass would yield more atoms.Atomic masses:Mg- 24.3 grams***F- 38.0 gramsP- 31.0 gramsNa- 23.0 grams***Note that fluorine is a diatomic moleculeThe sample of 45 g of sodium (Na) would contain the greatest number of atoms
What are mass of unstable atoms?
Unstable atoms are said to be radioactive
What would have the greatest mass 1 mole of iron atoms 2 moles of oxygen atoms 4 moles of carbon atoms or 1 mole of potassium atoms?
1 mole of iron atoms has the greatest mass - 55,845 g.
Why is the relative atomic mass of an element rarley a whole number?
Partly because many elements occur naturally as at least two isotopes, which have different mass numbers, and partly because may isotopes have actual masses that are different from their (always integral) mass numbers. This latter effect is most pronounced among ferrous metal atoms, which have the strongest nuclear binding energies of all atoms and consequently have less actual mass than the sum of the actual masses of all their constituent subatomic particles.
Why is the mass of an atom electrons not included in the atoms mass numbers?
Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state. The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.

Where does majority of a atoms mass come from?
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.
A dump truck a sports car and a bicycle are traveling at the same velocity's compare their kinetic energies?
the dump truck has the lowest kinetic the bike has the greatest becase of their mass
What was lavoisiers greatest contribution to science?
His atomic theory. He was the one who thought that there were atoms in everything.
Which subatomic particles account for most of an atoms mass?
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
How is nuclear binding energy related to the mass defect?
Nuclear binding energy is the energy required to hold the nucleus together. The mass defect is the difference between the mass of a nucleus and the sum of the masses of its individual protons and neutrons. The mass defect is converted into nuclear binding energy according to Einstein's famous equation, E=mc^2, where E is the energy, m is the mass defect, and c is the speed of light.
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
What is turned into energy when nuclear fusion?
Nuclear fusion is the phenomenon of binding two different atoms to produce a new atom, with a big release of energy.
What is the binding energy of a nucleus that has a mass defect of 5.81x10-29?
The mass defect represents the mass converted to binding energy
