there is 3
Lithium has 3 electrons and the Lithium ion has 2.
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.
The number of protons and electrons is identical.
Lithium has 3 protons, which means it also has 3 electrons to balance the charge. The number of neutrons in lithium can vary, as it can have different isotopes. The most common isotope of lithium, lithium-7, has 4 neutrons.
Lithium ions have three protons in their nucleus, as lithium's atomic number is 3. In terms of elections, a neutral lithium atom also has three electrons. However, when it is ionized to form a lithium ion (Li+), it loses one electron, resulting in two electrons. Thus, a lithium ion has three protons and two electrons.
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.
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, as an element, has an atomic number of 3. This means it has 3 electrons in its neutral state.
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.
The number of protons and electrons is identical.
6Li has 3 protons, neutrons and electrons. 7Li has 3 protons, 4 neutrons and 3 electrons.
The number of electrons is equal to the number of protons which determines it's atomic number. Therefore, the element with 3 electrons is the one with 3 protons which has an atomic number of three which is Lithium (symbol - Li, amu - 6.941)
Francium and lithium have the same number of valence electrons.
