2 in the first shell, 1 in the second
The neutral atom of lithium has 3 electrons.
A boron atom has fewer electrons than a lithium atom. Lithium has 3 electrons while boron has 5 electrons.
Lithium is a non metal element. There are 3 electrons in a single atom.
The boron atom has fewer electrons than the lithium atom. Lithium has 3 electrons in its neutral state, while boron has 5 electrons.
Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
one lithium atom is having three(3) electrons
Lithium is in the second period. It is an alkali metal. It has 2 rings of electrons.
Lithium is a metal element. There are 3 electrons in a single atom.
A lithium ion (Li+) has one less electron than a neutral lithium atom. This means a lithium ion has 3 electrons.
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.
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.
That depends what kind of ion it is: If its a +1 ion then it has 2 electrons. If its a +2 ion then it has 1 electron, and If its a +3 ion then it doesn't have any electrons. _________________________________________________ Usually the Lithium atom when ionized it loses its outer shell electron and hence remains with two electrons.
