Why does sodium fluoride have a higher melting point than lithium fluoride?
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
What type of metal has the lowest atomic weight?
lithium 6.941
What is lithium's molar mass?
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
How many moles in 15 grams if lithium?
From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
How many neutrons are there in the nucleus of an atom of lithium if the atomic number is 7?
The amount of neutrons can change among elements atoms of the same type element. These are called isotopes. Lithium actually has an atomic number of 3. An atomic number means how many protons it has. The problem most likely means that it has an atomic mass of 7. If that is true, it becomes easy. Atomic mass means the total weight of the element. A proton and a neutron each weigh '1.' All you have to do is look and see that lithium has an atomic number of '3' which means that it has 3 protons. You subtract that from the mass to get an answer of 4. This means that lithium in this example has 4 neutrons.Electrons aren't counted in the mass of the element because they weigh so little. That is the same reason why a neutron (which is technically a proton and an electron together) has the same weight as a regular proton.
What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
What is lithium atomic weight?
Lithium is a metal element. Atomic mass of it is 6.941.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
Is lithium a carbohydrate protein or lipid?
lithium is an element that has a extremely low atomic weight and is a mineral.
What type of metal has the lowest atomic weight?
lithium 6.941
What element has an atomic weight of 6.941?
That would be Aluminum (26.981538).
If lithium is only 95 pure is the atomic weight bigger or smaller?
95%
What is the lightest metal element?
Lithium is the lightest metallic element. Its atomic weight is 6.491.
What is lithium's molar mass?
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
What best describes the weight average of atomic mass on an element?
The atomic weight (not mass) of a chemical element is calculated considering the percentage concentatration of natural isotopes and the atomic mass (not weight) of each isotope.
What is the molar mass for lithium chloride?
Li2CO3 Li atomic weight is 6.94 C atomic weight is 12.00 O atomic weight is 16.0 Li2 has 6.94x2=13.88 C has 12.00x1=12 O3 has 16.00x3=48 13.88 +12.00 +48.00 ----------- 73.88 is the molecular weight....
1 gram equals how many moles?
It depends on what the substance is. For the elements, the number given as the atomic weight for an element on the Periodic Table is also the number of grams/mole. For example, lithium has an atomic weight of 6.941, so one mole of lithium would be 6.941 grams of lithium. In theory you can have a mole of anything -- electrons, ions, shoes, dollar bills, cars, etc...
