When these elements have five electrons on the outermost shell of electrons.
An atom is stable when its outermost orbit, or valence shell, is complete with the maximum number of electrons it can hold according to the octet rule. This typically means having eight electrons for most elements, except for hydrogen and helium which only need two electrons in their outer shell to be stable.
Elements in Groups 1 and 2 (alkali metals and alkaline earth metals) can easily lose electrons from their outermost shells. Group 13 elements like Boron, as well as Group 17 elements like Halogens, can also lose or gain electrons from their two outermost shells, though the valency may vary.
Yes, elements in the same family on the periodic table share the same number of valence electrons. Valence electrons are the outermost electrons in an atom, and they determine the element's chemical properties. Elements in the same family have similar chemical properties because they have the same number of valence electrons.
The Roman numeral at the top of a column on the periodic table indicates the number of valence electrons an element in that column has. Valence electrons are the electrons in the outermost shell of an atom and are involved in chemical bonding. Group IA elements have 1 valence electron, Group IIA elements have 2 valence electrons, and so on.
Eight electrons represent a complete (filled) outermost energy level for elements heavier than boron. This is because the outermost energy level can hold a maximum of 8 electrons according to the octet rule.

they are determined by the outermost shell of electrons
Elements in the same group have the same number of valence electrons.
Valence electrons are the electrons that account for many of the chemical and physical properties of elements. These are the electrons in the outermost energy level of an atom and are involved in chemical bonding and reactions. The number of valence electrons determines an element's reactivity and ability to form compounds.
all the electrons that are available in outermost shell
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
