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.
What atom has 3 protons and 3 neutrons?
An atom of lithium isotope 6Li has 3 electrons and 3 protons and 3 neutrons.
How many protons in lithium fluoride molecule?
lithium has 3 protons flouride has 9 protons so total of 12 protons in LiF.
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.
How many protons are in a lithium nucleus?
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science

What is the similarities between lithium 6 and lithium 7?
The number of protons and electrons is identical.
What atom has 3 protons and 3 neutrons?
An atom of lithium isotope 6Li has 3 electrons and 3 protons and 3 neutrons.
What is the relationship between elements and protons?
The number of protons in the nucleus is what defines the element. If there are 3 protons, it must be lithium. If there are 6 protons, it has to be carbon. Etc.
What is the difference between lithium 6 and lithum 7 on the periodic table?
Lithium-6 and lithium-7 are two different isotopes of lithium. All lithium atoms have 3 protons, but they may have different numbers of neutrons. Lithium-6 has 3 neutrons ans lithium-7 has 4 neutrons.
How many protons are there in atom of lithium?
Protons- 3Electrons- 3Neutrons- 4
What element has 3 protons and 3 electrons?
The only element with three protons is lithium.The isotope lithium-6, has 3 neutrons and is the rarer of the two stable isotopes of lithium.Most lithium is isotope lithium-7, containing 3 protons, 3 electrons, and 4 neutrons. It makes up about 92.5 percent of the lithium found on Earth.
How many protons does a lithium atom have?
Based on the atomic number of lithium there are three protons in a lithium atom.
How many protons do lithium-7 have?
Lithium has three protons because elements always have the same number of protons.
How many protons are there in the lithium?
All lithium atoms (ions or neutral) have 3 protons.
How many electrons and protons lithium have?
The element lithium has 3 protons and 3 electrons.
