Which element has four valence electrons

Any elements in Group 14, also known as the carbon group, will have four valence electrons. This group contains carbon, silicon, geranium, tin, lead, and flerovium. These elements are all in the same group precisely because of the same number of valence electrons.

A Lewis symbol consists of an elemental symbol surrounded by one dot for each of its valence electrons: Figure 5.1.1 5.1. 1 shows the Lewis symbols for the elements of the third period of the periodic table. Electron dots are typically arranged in four pairs located on the four "sides" of the atomic symbol.The valence electrons for main group elements are those with the highest n level. For example, gallium (Ga, atomic number 31) has the electron configuration [Ar]4s 2 3d 10 4p 1, which contains three valence electrons (underlined). The completely filled d orbitals count as core, not valence, electrons. Transition elements or transition metals.For groups 13 to 18, subtract 10 from the group number to get the number of valence electrons, e.g., elements from group 13 will have three valence electrons, from group 14 four valence electrons, and so on. A notable case is group 18, in which the elements (known as noble gases) have 8 valence electrons.The Group 14 elements, also known as the carbon group and the Group IV elements, is a group of elements on the periodic table.Each element has 4 valence electrons. Only carbon makes anions. Silicon and germanium are semimetals. Tin and lead are poor metals. Ununquadium, a radioactive element, is not stable enough to see its properties. All of them can form +4 oxidation state compounds.
