The atomic number of Lithium is 3. This method there room 3 protons, positively fee particles, in the cell core of a lithium atom. Over there are constantly the same number of electrons in an atom as the number of protons, if the atom has actually an all at once charge that 0. Thus, over there are...

The atomic variety of Lithium is 3. This way there space 3 protons, positively charged particles, in the cell core of a lithium atom. There are constantly the same number of electrons in an atom as the variety of protons, if the atom has actually an all at once charge that 0. Thus, there are three electron in a lithium atom.
When one atom loser an electron, the atom i do not care a positively fee ion. This is since now the variety of the positively fee particles, protons, above the number of electrons, therefore the net charge is positive. In the instance of lithium, if one electron is lost, the result ion has two staying electrons, and also a net charge of +1:
The net fee of three protons and two electrons is +3 + (-2) = +1.
If 2 electrons were lost, the result ion would have actually the fee +3 + (-1) = +2.
Therefore, the lithium atom needs to lose one electron to type an ion v a +1 charge.
