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's the difference between atomic number and atomic mass number?
Atomic number is the number of protons in a nuclide. This identifies the element. Mass number is the number of nucleons in a nuclide, a nucleon being a proton or a neutron. This, together with the atomic number, identifies which isotope of the element it is.
Determine the number of electrons in a neutral atom of lithium?
By consulting a periodic table, you can find the atomic number of lithium (which equals its proton number), as well as its average number of neutrons (represented by the mass number - simply take the proton number away from the mass number).
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)

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.
Lithium mass number?
Lithium's mass number is 6.941.
How many electrons does lithium 7 have?
A neutral lithium atom has 3 electrons, the same as the number of protons, which is the atomic number of lithium. There is no lithium ion with a charge of 7+. If you mean lithium with a mass number of 7, the number of protons is 3 and the number of neutrons is 4.
Which Atom has the greatest mass between Lithium Sulphur oxygen and sodium?
lithium
What is the mass number for lithium?
Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.
An atom that has 3 protons 4 neutrons and 3 electrons has an atomic number of?
The number of protons an atom has is equal to its atomic number. In this case, there are 3 protons, so its atomic number is 3 and this is lithium (Li), the third element on the periodic table. Atomic mass is sum of the number of protons and neutrons in the nucleus. Here, that is 3 and 4, respectively, giving our atom an atomic mass of 7. The number of electrons does not affect either the atomic number or the atomic mass, but instead determines the bonding properties of the atom and whether it has a charge. If the number of electrons is equal to the number of protons, as is the case here, the charge is neutral (0). If there are more electrons than protons, the atom will be negatively charged (5 electrons and 3 protons --> charge = -2), and if there are more protons than electrons, the atom will be positively charged (2 electrons and 3 protons --> charge = +1).
An atom of carbon-12 is about twice as heavy has twice the mass as an atom of?
lithium 6
Why is lithium more lighter than other alkali metals?
So it has the lowest atom number, the lowest mass as well
A neutral atom that has 8 protons must have?
8 electrons.
What's the difference between atomic number and atomic mass number?
Atomic number is the number of protons in a nuclide. This identifies the element. Mass number is the number of nucleons in a nuclide, a nucleon being a proton or a neutron. This, together with the atomic number, identifies which isotope of the element it is.
How many protons will lithium have if the mass number is 8?
lithium has 3 protons which would also be 3 electrons.
