Is the atomic mass of lithium-6 or 7?
The average atomic mass of lithium is 6.
What is the atomic mass of lithium-7?
7.016004 Lithium-7 atom is the stable isotope of lithium with relative atomic mass 7.016004, 92.5 atom percent natural abundance and nuclear spin 3/2.
What are lithium-6 and lithium-7?
Lithium is best known today as an ingredient of lithium-ion batteries. Li-7 as a hydroxide is important in controlling the chemistry of PWR cooling systems. Li-7 is a key component of fluoride coolant in molten salt reactors. Li-6 is a source of tritium for nuclear fusion, through low-energy nuclear fission.
How many neutrons does Li 6 have?
3 neutrons Size of a Nucleus Lithium-6 has 3 protons (as it must if it is to be the element Lithium) but only 3 neutrons, so it has a mass number of 6.
How do u calculate atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How many neutrons does lithium-6 have?
3 neutrons Lithium-6 has 3 protons (as it must if it is to be the element Lithium) but only 3 neutrons, so it has a mass number of 6.
How many electrons does lithium-6 have?
Summary
| Element | Lithium |
|---|---|
| Number of neutrons (typical isotopes) | 6; 7 |
| Number of electrons | 3 |
| Electron configuration | (He) 2s1 |
| Oxidation states | +1 |
How do we find atomic mass?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How many electrons does Li 6 have?

| Electron configuration | (He) 2s1 |
| Oxidation states | +1 |
What is the atomic weight of lithium?
6.941 uLithium / Atomic mass
How do we calculate atomic number?
The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.
How do you find the atomic mass of lithium?

What is the average atomic mass of lithium 6 and lithium 7?
The atomic mass of lithium-6 is 6.0151 amu and the atomic mass of lithium-7 is 7.0160 amu.
How do u calculate mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
How many protons does lithium-6 have?
3 protons Lithium-6 has 3 protons (as it must if it is to be the element Lithium) but only 3 neutrons, so it has a mass number of 6.
How do I calculate mass in grams?

How do you calculate the mass of a single atom?
In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .
