The number of electrons in each lithium atom is 3.
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.
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.
All lithium atoms will have the same number of protons (3) but can have different numbers of neutrons, resulting in different isotopes of lithium. Electrons are the same for a neutral lithium atom (3 electrons), but ions of lithium can have a different number of electrons.
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.
The number of electrons in each lithium atom is 3.
Lithium has 3 electrons and the Lithium ion has 2.
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.
Lithium ion is Li^1+ and the number of protons is 3 and the number of electrons is 2.
3: The total number of electrons in any neutral atom is always the same as the atomic number of the element.
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.
All lithium atoms will have the same number of protons (3) but can have different numbers of neutrons, resulting in different isotopes of lithium. Electrons are the same for a neutral lithium atom (3 electrons), but ions of lithium can have a different number of electrons.

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.
Lithium atoms contain one unpaired electron. Two of the three total electrons in a lithium atom are paired in its lowest energy s orbital, which can contain only two.
Lithium has three protons and three electrons. The number of electrons always equals the number of protons. Lithium has two isotopes, one with three neutrons and one with four neutrons.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
