Lithium loses one electron when fulfilling the octet rule. A neutral atom of lithium will have the same number of electrons as protons, 3. Therefore, a lithium ion will have one less electron, 2.
A lithium ion has 2 electrons. A lithium atom has 3 electrons and changes to an ion when it loses an electron.
three: 1s2 2s1
the answer in a chemistry test is always A!
A lithium ion has three protons and 2 electrons - Li+. A neutral lithium atom has 3 electrons, but loses one to form an ionic bond with a non-metal.
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.
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 has 3 protons and 3 electrons.
3 protons and 2 electrons.
Lithium ion is Li^1+ and the number of protons is 3 and the number of electrons is 2.
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.
The lithium ion will be stripped of its electron by the flouride ion, resulting in an ionic bond, where the lithium atom will have 0 valence electrons and the fluoride ion will have 8

Lithium loses one electron to become the cation Li+.
There are 3 protons and 2 electrons present in a lithium ion.

When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.
Lithium gives one electron to another atom to form a stable mono-positive ion.
