Why is the mass number of lithium 7?
6.941 is the average mass of lithium's isotopes. The majority of lithium (on average about 92.5%) is lithium-7 with 3 protons and 4 neutrons while about 7.5% is lithium-6 with 3 protons and 3 neutrons. A number of other isotopes exist but only in trace amounts.
In lithium atoms would all atoms be identical in terms of electrons neutrons and protons?
No. They will all have the same number of protons and electrons, but the number of neutrons will vary. This results in isotopes of lithium.
Which symbols represent atoms of the same element that are istopes?
The normal chemical symbol is used for the isotope with the addition of the atomic number (Z) at the lower left of the symbol and the atomic mass number (A) at the upper left as shown X.For example Li and Li represent two isotopes of lithium.Since all lithium isotopes have an atomic number Z=3, this number is usually omitted and the isotopes are represented by the symbols Li and Li. These are sometimes written as Lithium-6 and Lithium-7 or Li-6 and Li-7.
What is the total number of neutrons in an atom of 7 lithium 3?
The atomic number of lithium is 3, which means that there are three protons. The number of neutrons depends on the mass number of the particular lithium isotope. Mass number is the SUM of the protons and neutrons. An atomic number of 3 and a mass number of 7 means that there are three protons and four neutrons. Lithium has two stable isotopes, Li-6 and Li-7 which means that there are 3 or 4 neutrons, respectively. The atomic number of lithium is 3, which means that there are three protons.

Does the lithium have 3 protons 3 electrons and 4 neutrons?
It has 0 neutrons. The number relates to the number of nucleons in the isotope. Lithium must have 3 protons to be lithium, and 3-3 leaves 0 neutrons. ie. Carbon has 6 protons, so the isotopes Carbon-11 and Carbon-12 have 11-6 = 5 neutrons and 12-6=6 neutrons respectively. Lithium-3 is so unstable that it cannot be created, said another way, there is no bound state between 3 protons. The lightest lithium isotope is Lithium-4, which has a lifetime of about 9.1 X 10^-23 seconds, or 91 millionths of a millionth of a millionth of a second. Lithium-4 decays to Helium-3 by proton emission.
Which isotope element has 3 protons 4 neutrons and 3 electrons?
It is lithium(Li) . NB Most elements produce isotopes. Hydrogen has 3 isotopes. Carbon has 3 isotopes Chlorine has 2 isotopes. To name but a few.

6.941 is the average mass of lithium's isotopes. The majority of lithium (on average about 92.5%) is lithium-7 with 3 protons and 4 neutrons while about 7.5% is lithium-6 with 3 protons and 3 neutrons. A number of other isotopes exist but only in trace amounts.
What are the naturally occurring isotopes of lithium?
Lithium has two natural isotopes (6Li and 7Li).
Are lithium and beryllium isotopes?
no it is not
What is the most abundant isotope of Lithium?
7Li.It is one of the Primordial_elementsor, more properly, primordial isotopes, produced in Big Bang nucleosynthesis. Thus it is more abundant.
Do all lithium atoms have the same mass?
No. There are different isotopes of lithium which have different numbers of neutrons and thus different masses. There are two stable isotopes of lithium: Lithium-6 with 3 neutrons and Lithium-7 with 4 neutrons.
In lithium atoms would all atoms be identical in terms of electrons neutrons and protons?
No. They will all have the same number of protons and electrons, but the number of neutrons will vary. This results in isotopes of lithium.
What name is used to describe the different types of lithium atom?
Lithium salts, such as lithium carbonate (Eskalith)
What is different between the two isotopes of lithium?
Lithium-isotope 6 has 3 neutrons. Lithium-isotope 7 has 4.
How many ions does an lithium atom have?
AnswerLithium has 9 isotopes. 2 isotopes are stable and 7 are radioactive.Lithium has 9 isotopes. 2 isotopes are stable and 7 are radioactive.
How many neutrons are in an atom with an atomic number of 3?
The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li. If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.
How many neutrons does an atom of lithuim contain?
2 neutrons in He-4 isotope.
