Answer;
-3 electrons
Explanation;
-Lithium always has 3 protons: its atomic number is 3, and this is decided by its amount of protons (or by its nucleus' charge if you want to get more technical). Therefore, a lithium atom with neutral charge will have 3 electrons, too.
-Lithium has atomic number of 3. So a neutral lithium atom has 3 protons and 3 electrons. Two electrons in shell 1 and one electron in shell 2.
Answer:
total number of electrons required = 3
Explanation:
Lithium atom has 3 protons inside its nucleus
so the net positive charge on atom is due to these 3 protons
so in order to make it neutral we need same amount of negative charge on it so that net charge becomes zero on an atom of lithium
So we need 3 electrons on atom of nucleus as we know that
charge of proton = +e
charge of electron = -e
so we will have
[tex]Q_{proton} = +3e{/tex]
[tex]Q_{electron} = -3e[/tex]
[tex]Q_{net} = Q_{proton} + Q_{electron}[/tex]
