i guess you mean that the group 1 elements usually lose a electron in order to become stable because the outermost of the group 1 elements have only one valence electron and it is easy to lose one than to gain seven.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Elements react with other elements based on the number of electrons in their outer shell, also known as valence electrons. Elements are most stable when their outer shell is full, so they will either gain, lose, or share electrons in order to achieve a full outer shell.
Group 18 elements all have an outer shell of 8 electrons, s2 p6
Group 14 atoms have 4 p electrons in their outer shell. This group includes elements such as carbon, silicon, germanium, tin, and lead.
Number of valence electrons, that is, the number of electrons that the outer shell of an atom can hold. Ex. All halogens can have 7electrons in their outer shell. All gases have a full octet, eight electrons.
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
There are different electrons in the outer shell of each element.
Valence electrons (electrons in the outer shell)
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
There are 5, it is in group 5 on the periodic table of the elements
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
Fluorine has 7 electrons in its outer shell, while chlorine has 7 electrons in its outer shell as well. Both elements belong to Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
Elements in group VIA (6A) also called group 16.
Groups determine the number of electrons on the outer shell of an atom. When elements react, they want to complete their outer most shell. Filling the outer most shell is called the octet rule. In the cases of groups 1, 2 and 3, they want to donate, 1, 2 or 3 electrons to lose the outer most shell and form a completed outer shell.
Elements react with other elements based on the number of electrons in their outer shell, also known as valence electrons. Elements are most stable when their outer shell is full, so they will either gain, lose, or share electrons in order to achieve a full outer shell.
