how many valence electrons does lithium need to be stable?

Lithium, an alkali metal with three electrons, is also an exception to the octet rule. Lithium tends to lose one electron to take on the electron configuration of the nearest noble gas, helium, leaving it with two valence electrons. There are two ways in which atoms can satisfy the octet rule.

Best Answer: K is potassium. It has 1 valence electron Cl is chlorine, it has 7 valence electrons Since an atom needs 8 valence electrons to become stable.

Two lithium (Li) atoms can bond with one oxygen (O) atom, making the formula Li2O. Oxygen likes to have two additional electrons to make it happy. Each lithium atom provides one.

The Group 4 atoms have 4 valence electrons. The Group 5 atoms have 5 valence electrons. The Group 6 atoms have 6 valence electrons. The Group 7 atoms have 7 valence electrons.

Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.

Helium has 2 electrons --- both in the first shell (so two valence electrons). Lithium has 3 electrons --- 2 in the first shell, and 1 in the second shell (so one valence electron).

An aluminum atom possesses three valence electrons.

The halogen elements have seven valence electrons in their outermost electron shell. Therefore, when these elements can receive an electron from another atom, they form very stable compounds since their outermost shell is full.

It does not possess d orbitals in its valence shell. Due to this it is not able to expand its octet. The maximum covalency of boron cannot exceed 4. Therefore, boron is unstable to form BF6 3- ion.

A: Any element in group 1 has just one valence electron. Examples include hydrogen (H), lithium (Li), and sodium (Na). Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr).

The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons. Those groups have 1 and 7 valence electrons, respectively, making them desperate to bond to something, to achieve a stable configuration of 8.

Hydrogen ( Hstart text, H, end text), lithium ( Listart text, L, i, end text), and sodium ( Nastart text, N, a, end text), as group 1 elements, have just one electron in their outermost shells. They are unstable as single atoms, but can become stable by losing or sharing their one valence electron.
