Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
Both lithium and potassium have one valence electron
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.
A lithium atom has 3 electrons, with 2 electrons in the first energy level and 1 in the second energy level, making it stable. When it loses 1 electron to form the Li+ ion, it achieves a full valence shell (similar to a noble gas configuration) and becomes more stable. This is because the Li+ ion has a complete outer energy level, reducing its reactivity and increasing stability.
The number of valence electrons remains the same as you move across a row on the periodic table. For example, in row 2 (elements from Li to Ne), all elements have 2 valence electrons. However, the chemical reactivity of these valence electrons can change as you move across the row due to the increasing nuclear charge affecting their interactions with other atoms.
Lithium has one valence electron and tends to lose it to form a +1 ion. This results in the formation of lithium ions in compounds.
A lithium ion (Li+) has one less electron than a neutral lithium atom. This means a lithium ion has 3 electrons.

Lithium ion is Li^1+ and the number of protons is 3 and the number of electrons is 2.

Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.
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.
They do not. Helium has two electrons in its valence shell. Neon has eight, plus two more beneath the valence shell. However, since the first energy level can only hold two electrons, helium has a full valence shell, which explains why its properties are similar to those of neon.
Lithium (Li) has 1 valence electron. It is in the same 'family' as Sodium (Na) and Potassium (K)
