what are elements with few valence electrons found on the periodic table?
318122
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). Oxygen, like all the other elements in group 16, has six valence electrons.

As you know, an element's valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.

Magnesium is element 12 and belongs to Group 2 of the Periodic Table. An element in Group 2 has two valence electrons. Also, the electron configuration of Mg is 1s² 2s²2p⁶ 3s² or [Ne]3s². Since the 3s² electrons are the outermost electrons, magnesium has two valence electrons.

The alkaline earth metals have two valence electrons. The alkaline earth metals are in the second family on the periodic table.

Potassium has one valence electron. The valence electrons are only those in the very outermost electron shell.

Atomic and physical Tennessine is expected to be a member of group 17 in the periodic table, below the five halogens; fluorine, chlorine, bromine, iodine, and astatine, each of which has seven valence electrons with a configuration of ns2np5.

Potassium, an element in Group 1 of the periodic table(alkaline metals) has 1 valence electron. Number of valence(outer shell) electrons corresponds to the element's group number and therefore it has 1 valence electron.

The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons. The valence electrons are the electrons found in the highest energy level in the s and p orbital.

Potassium, chromium, and copper are the only elements in the fourth period that have one electron in the outermost shell. Wild electron configurations also mean you have a good chance at a variety of valence numbers.

The two elements that most commonly fail to complete an octet are boron and aluminum; they both readily form compounds in which they have six valence electrons, rather than the usual eight predicted by the octet rule.

Most elements on the periodic table are metals. Visually inspecting the periodic table shows that most elements are metallic.

Atoms of elements in this group have four valence electrons.

The noble gases are the only non-transition-metal elements that have eight valence electrons in their neutral, ground state configuration, but atoms of other elements can produce a full octet -- an outer shell with eight electrons -- by gaining or losing electrons.

Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.
