Element has much more than 4 valence electron :

Group 15,16,17,18Part of the change metal, Lanthanides, and actinidesFurther explanation

Valence electrons are electrons provided in creating bonds and are in the outer shell of an element.

The ar of the elemental group (especially the main group) in the periodic mechanism is identified by the variety of valence electrons pour it until it is full the last covering (the outermost electron shell)

For a transition metal, the can also be in one inner shell.

Subshells for valence shell:

Main group: ns, npTransition metals: ns, (n-1) d, npLanthanides and actinides: ns, (n-2) f, (n-1) d, np

Valence electrons for the main group:

Group 1 (alkali metals): 1Group 2 (alkaline earth metals): 2Group 13 (boron group): 3Group 14 (carbon group): 4Group 15 (nitrogen group): 5Group 16 (oxygen group): 6Group 17 (halogens): 7Group 18 (noble gases): 8

Whereas for:

Lanthanides and also actinides: 3–16

Transition metals: 3–12

From the explanation over shows that the facets that have valence electrons over 4 are:

1. The key group

Group 15 (nitrogen group): 5

Group 16 (oxygen group): 6

Group 17 (halogens): 7

Group 18 (noble gases): 8

2. The part of transition metals which starts indigenous the aspect Vanadium (V) to the right3. The part of Lanthanides i m sorry starts from the Neodymium (Nd) element to the right4. The part of Actinides which starts from the Uranium (U) aspect to the right
