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 does an atom of lithium-7 have as an equal number?
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
How many protons will lithium have if the mass number is 8?
Lithium with a mass number of 8 will have 3 protons. The mass number represents the total number of protons and neutrons in an atom's nucleus, and since lithium has an atomic number of 3, it means it has 3 protons.
What is the atomic number of Lithium-7?
The atomic number of an element is the number of protons in its nucleus. Since lithium-7 is an isotope of lithium, it still has 3 protons in its nucleus, which means its atomic number is also 3.
