When these elements have five electrons on the outermost shell of electrons.
valence electrons are the electrons in the outermost energy level
You can determine the number of electrons in the outer energy level of an atom by looking at its group number on the periodic table. For main group elements, the group number corresponds to the number of valence electrons. For example, group 1 elements have 1 valence electron, group 2 elements have 2 valence electrons, and so on.
The outermost principal energy level is the highest energy level in an atom where electrons are located. This level determines the chemical properties of an element, as it is the location of valence electrons that participate in chemical bonding.
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
2nd energy level, the electron arrangement is 2,1 at ground state
Halogen family members, or elements in group 17, have 7 valence electrons.
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.

The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
There are different numbers of valence electrons in different elements.
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
Their valence electrons are in the same energy level.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Boron has 3 valence electrons, gold has 1 valence electron, krypton has 8 valence electrons, and calcium has 2 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom.
