See the Related Questions for how to determine the number of electrons in the outermost shell of all the elements!
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
There are 2 electrons on the outermost shell of calcium.
Magnesium (Mg) has 2 valence electrons because it is in group 2 of the periodic table. Group 2 elements have 2 electrons in their outermost shell.
Both terms are acceptable due to the fact that eight electrons exist in the outermost shell of all elements in the group. Therefore, one could say that this group has 8 electrons in the outermost shell or that there are no electrons in the outermost shell - as the structure is stable! It is the perspective of a person.
For group 1 elements : lithium , sodium, potassium...etc All of them have one valence electrons , however Rubidium(Rb) have two valence electrons. Therefore, Cesium have one valence electrons. :D
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.
the same number of valence electrons (which is the same number of electrons in the atom's outermost shell)
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
group 1...is 1 valence. group 2...is 2 valence.
By the outermost shell of electrons
There are 2 electrons on the outermost shell of calcium.
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
Magnesium (Mg) has 2 valence electrons because it is in group 2 of the periodic table. Group 2 elements have 2 electrons in their outermost shell.

the elements belonging to group 1 and 2 of the Periodic Table are s-block elements. it includes elements in which the outermost subshell is s and that have 1 or 2 electrons in their outermost shell.
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.
