A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
An atom of carbon-12 is about twice as heavy has twice the mass as an atom of?
lithium 6
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
Is the mass of an iron atom any different from the mass of a copper atom?
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
The mass of an atom aftre it under goes fission or fusion?
the mass of the atom after fusion is less than the mass of the input atoms. The mass of the fragment atoms after fission is less than the mass of the original atom.
The mass of a proton is 1.00727252 you The mass of a neutron is 1.008665 you What is the difference in the calculated and rest mass of an atom of lithium?
0.1155 u
Which Atom has the greatest mass between Lithium Sulphur oxygen and sodium?
lithium
Explain the difference between atomic number and mass number?
Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.
A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
An atom of carbon-12 is about twice as heavy has twice the mass as an atom of?
lithium 6
How much does a lithium atom weigh?
The mass of 0.100 mole of lithium is 0,6941 g. This can be calculated from this equation: m=n*M where m is mass in grams, n is amount of unit in mole and M is molar mas in gram/mole. the molar mass can be found in periodic table, for lithium it is 6,941 g/mol
What mass number is calculated by adding the numbers?
the mass number of an atom is the number of protons in an atom, plus the number of neutrons.
Why atomic mass of atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.

Is difference of mass number is calculated by electron microscope?
no, the mass spectrometer.
