group 18, noble gases
The outermost shell of an atom is determined by the number of electrons it can hold, which is based on the atom's position in the periodic table. Atoms tend to fill their outermost shell with electrons to achieve stability, following the octet rule for main group elements. The outermost shell is also known as the valence shell and is responsible for an atom's chemical behavior.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The number of electrons in the highest energy level (outermost shell) for an element corresponds to its group number in the periodic table. For example, Group 1 elements have 1 electron in their outermost shell, Group 2 elements have 2, and Groups 13-18 have 3 to 8 electrons, respectively. Transition metals typically have 2 electrons in their outermost shell, though their electron configurations can be more complex due to d-orbitals.
As with all alkali metals, hydrogen has one electron in its outermost shell.
Bromine has four valence shell electrons. It is located in Group 17 of the periodic table, which means it has seven electrons in its outermost shell (the fourth energy level). Therefore, Bromine has four energy levels, with the outermost shell containing the valence electrons necessary for chemical bonding.
In the periodic table, group indicates the number of valence electrons in the outermost shell. E.g. Group I- the elements in that group have one valence electron in the outermost shell.
There are 2 electrons on the outermost shell of calcium.
Inert gases
no protons, one electron as it is in group I of the periodic table

Phosphorus is in group 15 (or group 5A) on the periodic table, not group 3. Group 15 elements have 5 valence electrons in their outermost shell.
Phosphorus has 5 electrons in its outermost shell. This means it belongs to group 15 of the periodic table and has a valence electron configuration of 3s^2 3p^3.
The group 3 of the periodic table include lanthanides and actinides.
Potassium has one electron on its outer shell. It belongs to group 1 of the periodic table, so it has one electron in its outermost shell.
There are 8 electrons in the outermost level of argon, which is known as the valence shell. Argon is in group 18 of the periodic table, so it has a full valence shell with 8 electrons.
